低反射率红外衰减片ASAHI SPECTRA

Low Reflective NIR-ND Filter

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.
