Product Variants of Optical Filter Glass
NIR Cut Filters
CHARACTERISTICS
Different glass compositions are used for NIR cut filters in order to optimize the properties for the respective application. SCHOTT filters cover any size requirement from a few micrometers to several millimeters in thickness. These filters are optimized for their optical properties and the different operating conditions. Our filters are suitable for optical thin film coatings providing additional properties. The internal quality is so high that the filters can even be placed directly in front of the sensor in imaging systems.
- Available with a variety of different edge positions and color gradations.
- The high optical quality enables distortion free optical images without stray light.
- Continuous melting technology and mass production provide low manufacturing tolerances, high homogeneity and ensure exceptional reproducibility.
- Steep transition from the transmission range to the blocking range.
- Optimized glass types for difficult environmental conditions.
Neutral Density Filters
CHARACTERISTICS
In the visible, these glasses are perfectly gray, but their homogeneous properties can also be used in the infrared range to uniformly reduce radiation intensity. SCHOTT's NG glass family comprises filter glasses of various grades of attenuation based on a robust silicate base glass. Thus, these filters can be used in almost all areas where light needs to be uniformly attenuated.
YOUR ADVANTAGES
- Special dimensions and oversized formats are available upon request.
- The high optical quality enables distortion free optical images without stray light.
- Continuous melting technology and mass production provide low manufacturing tolerances, high homogeneity and ensure exceptional reproducibility.
- Color-neutral absorption due to low wavelength dependence.
Protective Windows for LiDAR
CHARACTERISTICS
SCHOTT glass windows provide reliable protection to the LiDAR system’s sensitive electronics and optics. At the same time our materials are compliant with automotive regulations. The applied AR coatings enhance transmission, withstand harsh environments and the reflection color can be easily customized.
YOUR ADVANTAGES
- High transmission for the laser wavelength of the LiDAR.
- High mechanical strength.
- Optimized AR for large incident angles and customized reflection color.
- Available in black or clear visual appearance.
- Cadmium free glasses.
- Color-neutral absorption due to low wavelength dependence.
Cerium- and Samarium-doped Filter Glass
CHARACTERISTICS
By absorbing the Nd laser light, these filters reduce amplified spontaneous emissions and eliminate parasitic oscillation, thereby increasing the efficiency and power of the laser.
YOUR ADVANTAGES
- Standardized filter glass types in consistently high quality
- Specific customer developments possible.
- Customized designs are feasible.
Inquiry Glasses
Several melting technologies are available, from Labscale to full industry production, with the availability of special property measurements.
