D-TOP Optics

Configuration examples and characteristics of the optical system using the D-TOP

Micro Observation Interferometer

Mach-Zehnder interferometer that can be observed transmitted wavefront of the glass substrate of about 1mm.

R Measuring Interferometer

It is a device that uses an interferometer and measures the radius of curvature of the concave surface of the small curvature.

Coherent Length Measuring Machine

As a polarizing Michelson interferometer using PBS and 1/4 wave plate, we have measured the coherent length of the background light of the semiconductor laser.


TOP is configured using the catalog product primarily, but it may be requested a adapter, holder and base that are not in the catalog in order to fix a light source, special shape sample and detector.

It is the product that was reduced by one rank from the surface quality of Plano Convex Lens (SLB-P).
