Celestron Labs CB1000CF Compound Microscope

It was sold as new.... but it used, with fine grain beach sand found on componets inside the packaging.

Estuvo muy bien el envio en tiempo y forma y el producto llegó en perfectas condiciones y funciona muy bien.

For an inexpensive scope, this one checks all the marks. It has 4 objectives incuding an oil one. The highest power objs have spring loading to protect the lens. It has an aperture wheel with focusing mechanism to control the Fstop and focus of the light entering the slide, as well as a brightness adjustment on the LED source itself. The LED light is bright, not too blue, and doesn't get as hot as a regular bulb. The eyepiece objectives allow independent diopter adjustment so each eye can see clearly with or without glasses, and while there was some dust present, it's not overly distracting. I wish however that they came with rubber cups for eye relief, and dust covers for the lense tops (they do have covers for the end caps) The stage has smooth gearing for moving the slide around in 2 planes, and the slides clip in easily with a spring mounted slide grip, which I greatly prefer to the old school clips that held a slide down on the ends. Changing slides can be done in seconds with one hand. The focusing mechanism is another area I wish they had done differently. There are 2 different focusing knobs for coarse/fine and the fine adjustment focus kind of rides on the coarse adjustment and has limited travel. So you can only adjust fine focus so far before you have to re-center the focus knob, then use coarse focus again. This has you hunting back and forth often and makes focusing a chore. This is made worse by the lenses not being parafocal out of the box. Thus you will be racking focus a LOT as you change objectives and use the scope.
