CLAREX Near Infrared (NIR) Filter
CLAREX Near Infrared Filter transmits Infra-Red rays and absorbs visible rays.
- Transmits Near Infrared (NIR) Wavelength.
- There are 5 grades of NIR filters which transmit through the ranges of 670nm to 860nm.
- Steep Transmission Curve for sensor accuracy and responsiveness
- Excellent Optical Characteristics and weather resistance.
- No birefringence or double refraction allows unimpaired signal transmission.
- Addition of Hard Coat increases surface hardness to 6-8H
- Non-Glare surface texture can also be applied
- Anti-Reflection Coating surface treatment also available specifically designed for NIR wavelengths improves transmission up to 96%
- Versatile substrate suitable for laser cutting, milling, printing, forming etc.
- High Temperature grade available for applications in demanding environments.
