WebThe magnification obtained by an infinity-corrected objective is the ratio between the focal length of the tube Lens and the objective. The most common tube lens focal length used by Mitutoyo and most other manufacturers is 200mm. With infinity-corrected objectives you can change the tube lens focal length to create different magnification ... WebThe LIO-60X Infinity Corrected Microscope Objective Lens has a 60x magnification, 0.85 numerical aperture, and 0.3 mm working distance. It uses a standard RMS thread, 0.800-36. The lenses are anti-reflection coated for the visible spectrum. This LIO-60X objective is suitable for use with standard low power visible laser wavelengths. Specifications

WebJan 5, 2024 · If you have a DIN microscope objective (160mm tube length, not infinity corrected), then the focal length is given by the following: flange - object distance = 45 mm flange - image distance = 150 mm WebNA is commonly expressed as. NA = n × sinθa. where θa is the maximum 1/2 acceptance angle of the objective, and n is the index of refraction of the immersion medium. The limit of resolution of a microscope objective refers to its ability to distinguish two closely spaced Airy disks. Resolution (r) = λ/ (2NA) the quiet man watch

Specifications WebAug 31, 2024 · The numerical aperture does not change, so using a Nikon CFI 10x objective on a 100mm tube gives 5:1. When used this way, the Nikon CFI 10x objective will still cover an APSC-sized sensor, but the Mitutoyo will not. Both objectives cover APSC on a 135mm tube, and give 6.75:1. You don't want to go under 100mm for a tube lens as this may give ... the quiet mind cafe
