Main features:
The easy-to-use and durable frameless stage is driven by steel wire, so there are no longer protruding supports, thus avoiding accidental injuries or finger collisions caused by the supports. Its wear-resistant and unsupported design ensures the continuous and smooth movement of the stage. Component safety - to avoid losses caused by student misoperation. As the eyepiece, objective lens, and condenser lens are fixed to the microscope body before leaving the factory, there will be no detachment or separation of components during transportation and daily use.
The highly precise mechanical processing of the extremely smooth four hole rotating objective lens turntable ensures smoothness and durability during use. The objective lens turntable is equipped with a rubber ring that conforms to ergonomic principles and is easy to convert.
The mechanical stage focusing limit prevents accidental occurrence, and the focusing position can be locked, making it easier to refocus after replacing the sample. When the upper limit of the stage is locked, accidental contact between the objective lens and the carrier can be avoided, thereby preventing damage to the object and objective lens.
Main applications:
The Olympus UIS2 infinity correction optical system further improves optical quality, excellent image resolution, higher reliability and robustness, and outstanding image quality. As a standard configuration, the flat field objective lens can provide superior image flatness among similar microscopes. The CX21 microscope adopts the same UIS2 optical system as Olympus advanced microscopes. And for the first time, the flat field achromatic objective lens has been used as a standard configuration in teaching grade microscopes, providing high contrast and clear images with a clear range up to the edge of the field of view. The 6V20W high brightness halogen lamp of CX21 microscope provides clear and stable illumination with bright and uniform illumination. Its built-in non spherical condenser lens can provide bright and uniform illumination for images throughout the entire field of view. The Abbe condenser with optimized contrast is marked with a value corresponding to the magnification of the objective lens on the aperture stop of the Abbe condenser, which facilitates obtaining high-resolution and high contrast images.
Supplementary explanation for industry applications:
It is used for observing and studying biological slices, biological cells, bacteria, live tissue culture, fluid precipitation, etc. It can also observe other transparent or semi transparent objects as well as powders, small particles, and other objects. The left figure shows the inverted type of production, which is also an essential inspection equipment for food factories and drinking water plants to obtain QS and HACCP certifications.
