Anti-reflective coating is a surface optical coating that increases transmittance by reducing light reflection, resulting in clearer imaging of optical systems and stronger energy transmission at operating wavelengths. In complex optical systems, it can improve contrast by reducing scattered light in the system.

Dual Wavelength Anti-Reflective Coating

Dual wavelength anti-reflective coating is used for two wavelengths that are far apart. These optical devices are used for propagating visible laser calibration light and near-infrared light, or for propagating reference wavelength and tuning wavelength light.

Broadband Anti- Reflective Coating

When light passes through an uncoated BK7 glass substrate, approximately 4% of the light energy is reflected, and only 92% of the incident light energy can be obtained. If the system contains many optical components, the anti-reflective coating becomes particularly important.
