專業Low Reflective NIR-ND Filter廠商

• Flat transmission over the wide NIR wavelength
  Colored ND glass is not available in NIR wavelength.
• Reflection on the surface is low and helpful to avoid the ghost issue
  Conventional reflective ND filter has high reflection on the surface like mirror.
• Excellent environmental durability
  MIL-specifications compliant
  Stable spectral performance even in cryogenic temperature

Neutral density (ND) filter is convenient to attenuate the light flatly, and often used for many kinds of applications such as light adjustment on the monitor.
Low reflective NIR-ND filter supplied by Asahi can achieve both flat transmission over the wide NIR wavelength and low reflection on the surface simultaneously.
We can supply this kind of promising ND filter for NIR as well as visible wavelength.
