Biological Table-Top Microscopes
Always on the lookout for good, quality microscopes, we have found another option. Carson Optical has provided an affordable line of durable, well-built microscopes for use at the elementary and high school levels. Both have a sleek gunmetal gray finish on a cast metal construction, 10X widefield eyepiece, 360° rotatable eyepiece, instruction manual, and LED illumination with dimmer switches. One feature not included on this series is the built-in pointer. Some folks will appreciate this because they feel it gets in the way of their viewing, others will miss it because they feel it pinpoints the specimen being viewed.
The 40X-400X microscope (great for elementary students) has two sources of LED lighting, top and bottom. The bottom light allows you to view slides and other transparent objects, and the top light allows you to view solid or opaque objects - you can see Lincoln on the back of a penny, sitting inside the Lincoln Memorial! Students can view objects on a 90mm² at 40, 100, and 400 magnifications. Other features include spring mounted stage clips, a .65 fixed condenser, and a 6-hole disc diaphragm that offers 5 filter colors and one clear hole for varied viewing. There is no fine focus knob (coarse focus only), the knob turns a bit stiffly, and it doesn't have a slip clutch. This model can be operated by an AC 110V-240V adaptor or by 2 AA batteries; the lights do burn brighter when the microscope is plugged in.
The 100X-1000X is a bit different from our other microscopes at this level. It offers only 3 levels of magnification - 100X, 400X, and 1000X (for oil immersion). Most microscopes at this level offer a 40X magnification, but this company has chosen to leave off the lower magnification. This model offers a 115mm x 125mm mechanical stage, movable 1.25 Abbe condenser, iris diaphragm, filter holder, and separate coarse and fine focus adjustments with slip clutch. The set includes a dust cover, extra fuse, blue filter disc, and operates on AC only. Note that the immersion oil is not included but can be purchased separately, #43994.
Carson Optical has been in the business of quality optics for over 20 years, and the expansion into microscopes is a good one. They offer affordable options for your educational needs. ~ Donna
