Infrared glass

Ruisen optics can manufacture all kind of optical glass, optical filter, near infrared glass, transmission ultraviolet black glass, neutral grey glass, green glass, yellow glass, band pass optical filter etc. optical filter.
Application of optical element Optical element widely applies in many universities, research development, military, medical instrument and finance etc.
Optical filter is the kind of optical instrument which is used to choose the necessary radiation wave band! The classifications of optical filter are as follows:
1. Colorful optical filter. There are various kinds of colors for flat glass or bright film. The largest scale of radiation can be over 100 kilometers. It is widely used in the broad-band photometry instruments and phototropic visions.

2. Film optical filter. It can be divided into film absorbing optical filter and film interfering optical filter. If you are interested in the above any kind of optical filter, please be kindly connect with us! We will provide you a reasonable price.
