Features:

Spectral characteristics: Generally, it has high reflectivity in the visible light band, with a reflectivity greater than 90%, and high transmittance in the near-infrared band, with a transmittance greater than 90%.

Incident angle characteristics: There are two common types of incident angles: 0 ° and 45 °. The spectral performance may vary at different incident angles, and the spectral characteristics of cold mirrors can usually better meet design requirements.

Environmental adaptability: able to withstand a certain range of environmental temperatures.

Application fields:

In the field of projection display: In projectors, cold mirrors can reflect visible light from the light source, allowing infrared light to pass through, helping to improve image quality and reduce thermal load in the system, protecting the optical and electronic components of the projection system.

Laser system: used to separate visible light and infrared light, reduce the thermal impact of infrared light on other components in the laser system, and improve the stability and reliability of the laser system.

Optical imaging system: In infrared imaging systems, cold mirrors can reflect visible light and only allow infrared light to pass through, avoiding interference from visible light on infrared imaging and improving imaging quality.

Spectrometer: It can be used in spectrometers to separate and screen light of different wavelengths for more accurate analysis of spectral information.

With the development of optical systems towards high power and high integration,Cold reflector mirrorThe technological iteration focuses on:

Higher damage threshold: Suitable for high-energy density scenarios such as laser processing.

Broadband spectral coverage: extended to the mid infrared and long wave infrared bands.

Miniature design: meets the needs of portable devices such as consumer electronics and AR/VR.
