Feature:
1. Clearer: This lens is coated with high light transmittance, with high refractive index, and the image is brighter
2. Automatic Rebound: Spring protection device, can automatically rebound when touches the cover glass during observation to protect the lens from crushing the specimen
3. Brass Material: Made for brass material, fine workmanship, and fall prevention, exquisite and durable, chrome plated accuracy material for the shell
4. Wide Application: The screw interface size is the international standard RMS size, which can be used by most professional biological microscopes on the market
5. Basic Specifications: This lens has a magnification of 20X, common rail distance of 195mm, and parfocal distance of 45mm
How to Use:
Can be used after connecting with the microscope.
In order to facilitate observation, recommended to start observation at low magnification, more difficult to adjust at high magnification than at low magnification. According to the characteristics of the observed specimen, not all slices are suitable for observation under high magnification.
