High-Quality Achromatic Microscope Objective Lens - 20.2mm Interface, High Light Transmittance for Biology Lab & Research | Perfect for Cell Observation & Scientific Studies

Feature:1. Clearer Image: This lens is coated with high light transmittance, with high refractive index, and the image is brighter2. Automatic Rebound: Spring protection device, automatically rebound when touches the cover glass during observation to protect lens to avoid crushing specimen3. Brass Material: Made for brass material, fine workmanship, corrosion and fall prevention, exquisite and durable, plated accuracy material for shell4. Wide Application: Screw interface size is the international standard RMS size, can be used by most professional biological microscopes on the market5. Basic Specifications: This lens has magnification of 100X, common rail distance of 195mm, and parfocal distance of 45mmHow 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.Specification:Item Type: Achromatic ObjectiveModel: 100/1.25Material: BrassUse: Microscope AccessoriesInterface Size: Approx. 20.2mm / 0.80in (International Standard RMS Size)Magnification: 100XNumerical Aperture: Approx. 1.25mmCover Glass Applicable Thickness: Approx. 0.17mm / 0.007inMicroscope Applicable Mechanical Tube Length: Approx. 160mm / 6.30inWorking Distance: Approx. 0.13mm / 0.005inCommon Rail Distance: Approx. 195mm / 7.68inParfocal Distance: Approx. 45mm / 1.77inImpregnation Medium: Cedar Oil (OIL)Spring: Yes
