Optical Constant Measuring Device OptiSpheric
The OptiSpheric is a device that can measure effective focal length (EFL), back focal length (BFL), MTF (on axis), curvature radius, eccentricity (transmission, reflection) in a single unit, especially for small diameter lenses (from Φ1 mm to Φ35 mm).
Features
- You can select a reticle ( measurement chart) and a program for each measurement, and measure automatically and easily.
- The accuracy of each measurement complies with international standards, ensuring absolute accuracy and stable repeatability.
- The optical system of the device is simple and the structure is sturdy, and it has a maintenance-free design.
