TriOptics MTF station – Full optical characteristics, such as MTF measurement, F#, NA

MTF

MTF2

This optical bench measure the Pupil Size, F#, Focal Length, Resolution, Front and Back Working Distance.

Optical Bench

This instrument measure the optical axis for assembly or a single lens element. It also can measure focal length of the lens elements.

Optical Axis

Zygo Verifire Interferometer – measure the assembly wavefront, lens element curvature and surface accuracy.
