Interferometer & TS

Horizontal Interferometer

  1. Customizable:  According to the need to change different light source band or others.
  2. Strong practicality: The interferometers are suitable for small, medium and large optical processing companies and are very easy to operate.

As an optical processing company, we have a better understanding of the use and actual functions of interferometers.

Based on our optical vertical integration capability, we have developed our own brand of interferometer family.

The interferometers are suitable for small, medium and large optical processing companies and are very easy to operate.

Of course, we can also customize interferometers according to special requirements.

Vertical Interferometer

  1. High efficiency: It can be used in the industrial mass production for quick speed detection.
  2. Non-contact inspection method: to avoid surface damage.

PHASE SHIFT is applicable to optical machining site, which is easy to operate and has high test efficiency. The non-contact inspection method can be used to check the surface shape and radius of optical parts, as to avoid surface damage and there is no need to make test samples.

Transmission Spheres

MTS lens is a kind of precision lens with high quality that is specially used in the interferometer measurement for the surface shape of the optical part and the wave front of the optical system.  The reference lens is made with fused silica.  The precision of the reference lens can reach λ/20 or even higher.
