Trinocular head with 360° rotation Magnification range from 40x to 2000x Four achromatic DIN objectives: 4x, 10x, 40x, 100x (immersion) Coaxial coarse and fine focus controls 1.25 N.A. Abbe condenser with iris diaphragm 140mm x 140mm mechanical stage Includes 10 prepared slides and imaging adapter Description FAQ Specifications In the Box Warranty Celestron Labs CB2000C Compound Microscope The Celestron Labs CB2000C Compound Microscope delivers a powerful magnification range from 40x to 2000x through its four DIN achromatic objectives and included 10x and 20x eyepieces. Its trinocular head rotates a full 360° for comfortable sharing, while the 1.25 N.A. Abbe condenser and iris diaphragm provide precise control over specimen illumination. The large 140mm x 140mm mechanical stage and coaxial focus knobs allow for exact positioning, and the included 10 prepared slides ensure you can begin detailed observations immediately. 40x to 2000x Magnification with 4 DIN Objectives The CB2000C's optical system is built around a quadruple rotating nosepiece holding four achromatic DIN-standard objectives: 4x, 10x, 40x, and a 100x oil immersion lens. Combined with the two included eyepieces (10x and 20x), you get a massive magnification range from 40x for locating specimens up to 2000x for resolving fine cellular structures. The achromatic objectives are designed to correct for color fringing, ensuring clearer, more accurate views. Professional Illumination: 1.25 N.A. Abbe Condenser & Iris Control Proper illumination is critical for high-magnification viewing, and the CB2000C excels with its advanced lighting controls. The height-adjustable 1.25 N.A. Abbe condenser focuses the lower LED light onto the specimen for maximum resolution, especially with the 100x objective. The integrated iris diaphragm allows you to precisely control the beam's diameter, adjusting brightness and contrast to reveal subtle details in your slides. Precision Control: 140mm x 140mm Mechanical Stage & Coaxial Focus Finding and tracking a subject at high power requires smooth, repeatable movements. The CB2000C features a large 140mm x 140mm all-metal mechanical stage with dual-axis control knobs for precise slide manipulation. The coaxial coarse and fine focus dials let you quickly achieve initial focus and then make minute adjustments with 0.2mm of travel per rotation, preventing you from overshooting the focal plane when examining bacteria or other microorganisms. Imaging-Ready Trinocular Head with 360° Rotation The key feature of the CB2000C is its trinocular head, which includes a dedicated port for attaching a microscope camera using the included adapter tube. This allows you to capture images and videos of your discoveries without sacrificing the binocular viewing eyepieces. The entire head rotates 360°, making it easy to share the view with others in a lab or classroom setting without moving the entire microscope. What is the purpose of the 100x immersion objective on the CB2000C? The 100x objective is designed for the highest magnification levels (1000x with the 10x eyepiece, 2000x with the 20x). It requires a drop of the included immersion oil between the lens and the slide cover. This oil prevents light from bending away from the objective, dramatically increasing the resolution and brightness needed to see extremely small specimens like bacteria or cell organelles. How do I power the Celestron Labs CB2000C microscope? The CB2000C is powered by the included universal AC adapter, which supports 100-240V input. It comes with four interchangeable plugs (types A, C, G, and I) to ensure compatibility with power outlets in most regions. The microscope does not have an option for battery power. Can I adjust the lighting on the CB2000C? Yes, you have multiple levels of control. The lower LED illuminator has a brightness adjustment dial. For more advanced control, you can raise or lower the 1.25 N.A. Abbe condenser to focus the light and adjust the iris diaphragm to change the contrast and depth of field. The kit also includes three color filters (blue, green, white opaque) to further enhance visibility for specific specimens. Is the Celestron CB2000C ready to use out of the box? Absolutely. The microscope comes with 10 professionally prepared slides, including specimens like a lily anther, small intestine, and Aspergillus. This allows you to start making observations and exploring the full magnification range as soon as you set it up. How does the trinocular head benefit me? The trinocular head provides a third port specifically for mounting a camera, using the included adapter. This means you can have a camera attached and ready to capture images or video at any time, without needing to remove one of the viewing eyepieces. It's ideal for documentation, teaching, or sharing your findings with a larger audience. What does the mechanical stage on the CB2000C do? The 140mm x 140mm mechanical stage holds your slide securely. It has two knobs that allow you to move the slide smoothly left-to-right and forward-to-back. This is essential for systematically scanning a slide or precisely centering a specimen in the field of view, especially at high magnifications like 400x or 1000x.
