VI-1010 Visible VideoMTF® Image Analyzer
This VideoMTF® image analyzer uses a high sensitivity CCD camera to acquire the image formed by visible to near-infrared optical systems. The main body includes an integral tube lens for image relay from infinite conjugate microscope objectives. A reflex finder with flip mirror facilitates image alignment.

Optikos offers VideoMTF® image analyzers based on several different types of sensors. If a specific test requires a different camera than those listed, it is likely that we can integrate a customer-specified analog or digital camera for use with a VideoMTF® system.
Visible Microscope Objectives
All Optikos microscope objectives for image analyzers are plan apochromats with chromatic aberration corrected over a broader range than standard achromats. A high quality relay optic magnifies the image of the optical system under test to increase the range of spatial frequency measured. High N.A. objectives capture the entire output of fast optics or systems working at large off-axis angles. Other special purpose objectives can be supplied upon request.
