· It is an ND filter used when attenuating high power lasers and wide wavelength range light.
· Non-transmissive light is not absorbed by the glass, so there are no concerns about glass damage due to high temperatures.
· Metal film reflection enables very gradual transmittance wavelength characteristics for ultraviolet rays through infrared.
· Thickness of the glass is 2 mm ±0.1 mm, uniform regardless of the transmittance.
· * Chromium film is absorbent and cannot be used for high energy pulse lasers.
· * Beams may be condensed due to heat lens effects when the high-power laser enters the filter.
· * Use variable beam splitter (VBS) with high power laser and high energy laser.
· * The laser beam reflected on the filter surface is dangerous.
· * Terminate reflective beams to avoid exposing workers to irradiation.
· * If the laser beam vertically enters the filter, the light reflected by the filter will return to the laser light source.
· * Laser oscillation will become unstable with this kind of optical feedback.
· * Slightly incline the filter for use so that optical feedback will not return to the laser source.
· * Filters with 92% transmittance rate (model FND-92, MFND-92) are planar substrates non-coated on both surfaces.
· * Transmittance will be approximately 92% due to reflectance loss of 4% (8% on both surfaces) on the non-coated surface.
