Compound microscope with 40x to 800x magnification Includes two eyepieces (10x and 20x) and three objectives (4x, 10x, 40x) Dual upper and lower adjustable LED illuminators Powered by universal AC adapter or 3 included AA batteries All-metal construction with an 88mm x 88mm stage Comes with 10 prepared biological slides for immediate use Description FAQ Specifications In the Box Downloads Warranty Celestron Labs CM800 Compound Microscope The Celestron Labs CM800 Compound Microscope provides a complete biological viewing toolkit with six magnification levels from 40x up to 800x. Its combination of two wide-field eyepieces (10x and 20x) and three achromatic objectives (4x, 10x, and 40x) delivers clear images for students, hobbyists, and lab technicians. Powered by either a universal AC adapter or three AA batteries, the CM800 is ready for use in the classroom, at home, or out in the field, with an 88mm x 88mm stage to hold your specimens. 6 Magnification Levels from 40x to 800x The CM800 offers six distinct levels of magnification for detailed biological study. By pairing the included 10x and 20x eyepieces with the three objectives on the rotating nosepiece, you can achieve magnifications of 40x, 80x, 100x, 200x, 400x, and 800x. The all-metal, refractive objectives are achromatic to minimize color fringing and produce more natural-looking images. Dual Upper & Lower LED Illumination This microscope features two independently adjustable LED illuminators, allowing you to view both translucent and opaque specimens. Use the lower illuminator for traditional slides, with a rotating disc diaphragm offering six aperture sizes to control contrast. For solid, opaque objects like insects, coins, or plant leaves, the upper illuminator provides direct, cool-to-the-touch lighting for surface inspection. All-Metal Frame with AC and 3-AA Battery Power Built on a strong, all-metal chassis, the CM800 is a stable platform for viewing. Its key advantage is its dual power system. Use the included universal AC adapter with four international plug types for continuous power in a lab or classroom. For portability and fieldwork, insert the three included AA batteries for hours of use away from any outlet. 10 Prepared Slides for Instant Discovery The Celestron CM800 comes ready for exploration right out of the box. A set of 10 professionally prepared slides provides a diverse range of biological samples to examine at every magnification level. This curated collection guarantees exciting and educational viewing from the moment you set up the microscope. Included Specimens: Wall of stomach, Testis, Aspergillus, Small intestine, Lily anther, Hydrilla verticillata leaf, Spirogyra, and more. What magnifications can I achieve with the Celestron Labs CM800? The CM800 provides six magnification powers: 40x, 80x, 100x, 200x, 400x, and 800x. These are achieved by combining the two included eyepieces (10x and 20x) with the three objective lenses (4x, 10x, and 40x). Can I view solid objects like coins or insects with the CM800? Yes. The CM800 features both upper and lower LED illuminators. The upper illuminator is specifically designed to light the surface of opaque, solid objects, making it suitable for viewing details on items like coins, stamps, insects, or plant leaves. Is the Celestron CM800 microscope portable for field use? Absolutely. The microscope can be powered by three AA batteries (included), making it fully portable for use outdoors, in the field, or anywhere an AC outlet is not available. It also includes a universal AC adapter for standard indoor use. What kinds of specimens can I see with the 10 included slides? The 10 prepared slides offer a great introduction to microscopy with a variety of samples. You can explore plant structures like a Lily anther and Spirogyra, fungi such as Aspergillus, and animal tissues including sections of the small intestine and testis. Does the CM800 have a fine focus control? No, the Celestron Labs CM800 features a coarse focus only mechanism. The rack and pinion system is designed for simplicity and is effective for navigating through the magnification range, but it does not have a separate fine-adjustment knob for micro-focusing at the highest powers. What is the purpose of the rotating disc below the CM800's stage? That is the stage diaphragm. It is a simple disc with six different aperture sizes. By rotating it, you can control the amount of light from the lower illuminator that passes through your specimen, which allows you to adjust the image contrast for better viewing.
