Cold Mirror 25.4mm Square

CLDM-25.4S3.3

The principle of the cold mirror is reflecting the visible range light and leave the UV range light to transmit. It can separate the visible and the UV (heat) of the sunlight.
◦Low absorption with a dielectric multi-layer coating using high transmittance glass material and it can be resistant to rapid change in high temperature.
◦Using this product it is possible to select IR light only.
◦Can be used as a NIR filter by changing the angle of Incident.

Guide
  • B270® is a registered trademark of SCHOTT AG Inc.
  • Different size, wavelength and deviation ratio not mentioned on-line or in our catalog are available as custom products upon on request.
  • For a suitable filter holder, please contact our Sales Division.
Remark -
Attention
  • Do not use cold mirror with high power laser and high energy pulsed laser. We can provide dichroic filters (TFMHP) suitable for use with pulse lasers, please contact our Sales Division.
  • WEB Reference Catalog Code/W3006
  • The backside of the cold mirror is not coated with AR, please use the dielectric coating side for visible light incident. The backside may have 10% of loss of energy and the ghost image may occur.
  • The visible light is reflected, the UV (heat) is transmitted, avoid blocking the transmitted light by a reflective element which may hold the heat.
  • The reflecting light may be mixed with infrared if the incident angle is other than 45 degrees.
