Infinity Optical System
Infinity optical system Sinowon IMS-310 Inverted Metallurgical Microscope means the light travels in parallel rays after passing through the microscope objective. A tube lens, inserted into the light path, causes the parallel rays to converge so that they come into focus at the eyepiece diaphragm.
The tube length (the reference focal length) ranges between 160 and
Infinity optical systems allow introduction of auxiliary optical components into the optical path with only a minimal effect on focus and aberration corrections.
Parfocality, in addition, can be maintained between different objectives in a matched set. Correction for any optical aberration can be accomplished through the tube lens or through the objective.
Infinity optical system provides greater system flexibility than finite systems in allowing optical components to be inserted between the objective and the tube lens thereby increasing the capabilities of the microscope system.
