AmScope PA100X-IRIS Finite Plan Achromatic Darkfield Objective Lense with 100X Magnification and 160mm Tube Category_Student Microscopes/High Power (Compound) Sliding binocular head with adjustableThis is a 100X dark field objective lens for biological DIN standard microscopes. Standard bright field objective lenses present low contrast due to their high numerical apertures. This lens' built in iris provides control over the aperture, varying between 0. 31 and 1. 25. This allows for the intensity of the dark field contrast to be easily adjusted. Compatibility Optical System Finite Mechanical Tube Length 160mm Mounting Thread RMS 20. 32mm
