The Celestron CB2000CF Lab Series microscope, is a great microscope for the money, it is well made and has all the features one could want. Features include: magnification from 40X to 2000X with 4 objective lens the highest is 100X which is also oil rated for using immersion oil at 1000X and 2000X. It uses built in LED illumination with an Abbe condenser and iris all of which, are adjustable. The stage has a spring loaded slide holder and is fully position adjustable using a single control shaft. The stage is elevated or lowered to focus using both coarse and fine focus knobs. The microscope comes with 2 sets (dual eyepiece) of eyepieces 10X with pointer and 20X. The eyepiece holder is adjustable for interpupillary distance as well diopter adjustments for each eyepiece. It also comes with immersion oil, 3 color lens for the iris, and a set of 10 prepared sample slides to view. I have not used it extensively but I have viewed several of the prepared slides using all the magnification settings, adjusted the illumination levels and condenser and iris and they all work well delivering crisp clear images. I actually had a decently clear image at 2000X but it would improve much using immersion oil. For the amount of money spent this is an excellent microscope.

Minus 3 stars, specification states Halogen Bulb, it is an LED bulb see pictures. No Spare bulb. Searched for "Generic" replacement, it seems this bulb is custom (sole source) and must replaced through Celestron. That is a deal killer for me. Did set it up, had a speck or two of dust that was easily removed, really liked it; but there is no telling how long these custom LED bulbs will be available. If this doesn't bother you, add stars. Also suggest you leave the LED bulb on for at least 14 days continously - to avoid infant mortality (search for electronics infant mortality - bathtub curve). Every thing else seemed okay (smear of glue on side panel). Really like the scope (basics performed) and packaging - was planning on building a wooden box around it. 7-5/8" x 18.5" x 11-1/4"

This is a nicely designed microscope. For someone interested in Microscope, I think it would be quite adequate.However..........my microscope was somewhat shabby in it's assembly. The optics were a bit off out of the box and this can be a huge headache to align. As you can see from the photo (cover off), the prism is so misaligned, they couldn't/didn't put the 3rd screw in.This is more of a Quality Control thing at the factory and chances are yours will most likely be OK. I suppose I could have tried to go the route of returning it, but this in itself would of being a large hassle.So since I'm still trying to align things (and yes probably not covered by warranty because of that), I can only give it a max of 2 stars.

I'm having a difficult time focusing it. Waiting for my brother to come help. Must be doing something wrong. First Microscope ever.
