Celestron Labs CB2000C Advanced Biological Trinocular Microscope review
Design
The CB2000C Advanced Biological Trinocular Microscope by Celestron Labs has been designed with a telephone number of aims : to be robust , to give stereo images , to permit for a secondary viewer and to give a professional feel via a number of proficient feature .
The hearty , encompassing infrastructure gave a confident sturdiness to this microscope . Coupled with eminent - caliber materials such as a metal body and glass eye , this machine felt up reassuringly robust . At 5.5 kg ( 12lbs ) , it is one of the heavy pupil microscopes , but has a strong carry handle and is unbelievable to be used by low children . The knob and dials all fit and sprain well and felt undestroyable in use ..
Secondary spectator capability has been made potential by attaching a third eyepiece vacuum tube to the header . Trinocular viewing allowed us to observe the specimens ocularly , in real time . To deal with the modification in lite saturation that comes with a trinocular microscope , Celestron Labs has designed a binocular to trinocular button , so that the trinocular eyepiece tube is not clear when not in enjoyment . Thus , optimum clarification can be achieve through the binocular eyepieces .
The swing-out filter holder shows a blue filter. This gives improved resolution as it color-corrects the halogen bulb’s yellow light and it appears more white. Some viewers also experience reduced eye strain with a blue filter.(Image credit: Heather Barker)
Additionally , as the wanton pathway moves independently through each binocular eyepiece , stereo images are observed .
We were impressed to witness that the CB2000C by Celestron Labs has been designed with numerous feature film that automatically and optically ameliorate the lineament of images potential with a mid - range microscope and facilitate it to know up to its ‘ in advance ’ title .
Firstly , take a quartet nosepiece has enable four objective lenses to be fitted , from 4X to 100X. Although we want to set up the head , the lenses screwed in securely and easily . As the binocular eyepieces came in 10X and 20X , we achieved a range of magnification from 40X to 2000X , resulting in a intent that could be used to take in specimen from whole worm all the way down to organelles inside body cells .

second , the swoop time is activated from the side and is safe and unnoticeable . The XY mechanically skillful stage had a decent motion , 140 mm x 140 mm , and was smooth and easy to maneuver , making slide navigation a pleasure .
A third invention mechanism is to have the jolty and ok focusing knobs rotating about the same axis of rotation . This coaxial movement is more ergonomic as the hand can remain in the same billet throughout operation .
in conclusion , the CB2000C has multiple ways in which light can be altered . The halogen illuminator is adjustable , so can be dimmed or made brighter where necessary . The Abbe condenser is transferrable and can be raise and lowered only with the Abbe adjustment knob . For direct the light onto the slide , the iris diaphragm can be opened or closed as required .
Binocular viewing, to suit an individual’s interpupillary distance, is possible via a horizontal slide. Each binocular eyepiece can be further adjusted with its diopter.(Image credit: Heather Barker)
at long last , this Celestron Labs Microscope get along with three filter to raise images . A frosted one to permeate the light , a blue filter to colour - correct the yellowish Christ Within from the halogen bulb and a green one to make the images clearer .
Overall , we were impressed with the amount of ripe features that have been deploy to ensure the Celestron Labs Advanced Biological Trinocular Microscope feels professional and deserving its mid - range price tag .
Performance
Having an abundance of ripe mechanically skillful , proficient and optic feature and bear the Celestron name , we anticipated a luxuriously - execute precision instrument when reviewing the CB2000C. While the eminent - quality field glass optics , range of lense and miniature choice did drive home in terminus of stereo images with high resolution and high power magnification , it was hugely thwarting that a number of quality control consequence made using the microscope vexatious and less gratifying .
place up the binocular interpupillary distance using the binocular tube slide and the diopters was fiddly , but worth it to see the inclined chute in 3D. Some more economical stereo microscope give three - dimensional look-alike at the expense of magnification . The CB2000C fashion model , by Celestron Labs , exhibit superb layering of spirogyra algae at low magnification . At high power , using the blue filter , we were able to identify subcellular bodily structure such as the core , chloroplasts , cytoplasmatic filament and the cellular telephone rampart . The blue filter helped to reduce some visual granularity seen at magnifications of 400X and above .
The XY mechanical stage performed flawlessly and was still , well functioning and a pleasure to use . The slide clip provided a unassailable fastening for the slide and permit straightaway and prosperous rally of lantern slide .

The chief downside to this picky microscope was with quality ascendance . There seemed to be a problem with either the focusing knobs or the stage . The knobs felt smooth and moved the stage up and down to achieve focal point with ease . Unfortunately , the mechanics did not hold centering and when the focusing knobs were n’t being held , the image went went fuzzy instantly and was whole out of direction within a few seconds . While inquire the job , we acknowledge that the degree visibly fell downwards once free to do so . Over a minute , the level lowered by 5 mm ( 0.2 - inch ) . We finagle to reduce this distance by spark the point peak restriction switch , but it was still noticeable enough to vitiate center and regard clarity .
Although we could still achieve focusing and trial run functionality , by keeping hold of the jolting focusing knob , doing so limited the amount of freedom we had to perform multiple operations . It is good to have both helping hand liberal to simultaneously switch objective electron lens , voyage the sliding board , set elucidation etc . It is also all-important for focal point to be hold while two - handed task such as changing a slide , filter or lens system are carred out .
Functionality
When considering the functionality of the Celestron Labs CB2000C Advanced Biological Trinocular Microscope , we need to be aware of the impact of simultaneously using multiple procedure . We also need to address its trinocular function as a dick for instruction and its production of stereophonic imagery .
It is also worth cite that the CB2000C , by Celestron Labs , needed setting up before manipulation : it is not supplied ready for economic consumption . It is quite usual to have to insert the eyepiece Lens , especially if they are standardised anyway . However , the CB2000C needed much more construction than is stock .
The head needed to be sneak in into the microscope arm and take locking into spot . The four objective lens system need to be securely chicane into the nosepiece holes , in the right order . Additionally , the trinocular ocular electron tube needed to be screwed into the headway and an eyepiece crystalline lens attached . On the positive side , detailed pedagogy for this set - up process were included in the user manual of arms , in multiple language , and were simple to follow .
Celestron Labs’ Advanced Biological Trinocular Microscope has a wealth of mechanical adjustments to increase its performance: an adjustable height condenser, XY slide navigation, rough and fine focusing knobs, an adjustable diaphragm and a swing-out filter holder.(Image credit: Heather Barker)
As a tool for teaching , the CB2000C by Celestron Labs relies on junior-grade viewing via the trinocular thermionic valve . tutor can view a educatee ’s specimen while in use , without disturbing them . We find this hugely beneficial when pointing out impudence cells , subcellular structures and insect physique . Note that the trinocular ocular genus Lens will always be a different magnification to the binocular eyepiece lens because there are only two of each type . This will affect both the solving and theatre of thought observe by each spectator . At one point we did have three users , one on each ocular . Although this made stereo system viewing impossible , it was great for collaborative work .
The modern feature all functioned well together , to activate the conception of good timbre epitome . sail the sliding board using the XY mechanical stage increased functionality if go while focusing at varying magnifications . luminousness could pinpoint the specimen using a pocket-size diaphragm aperture . Once rake the slide , wanton intensity could be adjusted with the illuminator knob , or by changing the Abbe condenser pinnacle or iris diaphragm .
We found the knobs to be ergonomically range and we were able to master the microscope by feel , rather than having to appear . To minimise the risk of lense damage , Celestron Labs has added a top restriction knob . This is particularly good for forestall harm to longer , eminent - top executive lenses .
Celestron Labs set up the Advanced Biological Trinocular Microscope with the eyepiece tubes opposite the microscope arm, and the stage and objective lenses towards the user. This felt counterintuitive at first but didn’t take long to get used to.(Image credit: Heather Barker)
One functionality issue was with the Abbe condenser . It has been project to have an adjustable peak , to serve control illumination — a lovely estimate , in theory . However , when focusing requires the stage to be moved downwards , it grabs onto the Abbe capacitance . When the degree is raised , it then pulls the optical condenser up with it , rather than let the two move independently . Perhaps this is another tone control issue , rather than being intentional . Whatever the reason , it would be good if this did not happen .
In summary , we enjoyed using this microscope for pedagogy , and students report that they liked being able to regard in three dimensions . We were sometimes frustrated by quality control progeny but could see beyond these , to agree that the CB2000C has a lot of potential as a trinocular biological microscope with multiple advanced features . We advocate the Celestron Labs Advanced Biological Trinocular Microscope for exercise in professional or pedagogy testing ground , for bud microbiologists with a petty experience .
Should you buy it?
✅ You want to upgrade to a mid - range microscope : The XY navigation , choice of illumination and quadruple nosepiece offer average substance abuser a more professional and robust optic official document .
✅ You would like to view your specimens in 3D : The freestanding range from both eyepiece metro combine to create a three - dimensional image .
❌ You would like to see solid specimens : There is no top light option with the CB2000C Advanced Biological Microscope .
A quality control issue with the focusing knobs allows the stage to fall slightly, resulting in the microscope losing focus. The focusing knob has to be held in position by hand to keep focus.(Image credit: Heather Barker)
❌ You have impaired sight in one eye : The stereoscopic picture showing capacity depends on opthalmic information from both eyes .
The Celestron Labs Advanced Biological Trinocular Microscope has a wealth of social occasion that will give an experient user the opportunity to misrepresent min detail of their optical images , and to catch unmortgaged , highly magnified biological specimen . We advocate this mid - range microscope for home , schooltime or laboratory use , for inquiry or teaching purposes , if you desire a stereo double .

For a binocular chemical compound microscope , the CB1000CF by Celestron Labs is ideal if you do not need stereo viewing . It come with a humiliated price tag , too .
How we test
During an grownup learning academic term , the microscope was constructed and set up . Users learned how to produce and take in slides of their own cheek cells , as well as folio Sir Robert Peel from a variety of different plants ; to observe stomata dispersion . Collaborative viewing and give-and-take was potential due to the trinocular ocular tube .
subsequently , we had spare rein with the prepared slide that came with the CB2000C. We experiment with lighting selection via the adjustable condenser altitude , changing the diaphragm dilation and inquire the image conflict with the supply filter .
