Features
- This is an ND filter ***d for high-power lasers and for dimming light in a wide wavelength range.
- Light that does not transmit is not absorbed by the glass, so there is no need to worry about the glass getting hot and breaking.
- Since it is reflected by a metal film, it shows very gentle transmittance wavelength characteristics from ultraviolet to infrared.
- The thickness of the glass is 2 mm±0.1 mm and is constant regardless of the transmittance.
- * Since chromium film has absorption, it cannot be ***d for high-energy pulsed laser.
- * When a high-power laser is injected into the filter, the beam may focus due to the thermal lens effect.
- * Use a variable beam splitter (VBS) for high power lasers and high energy lasers.
- * The laser beam reflected by the surface of the filter is dangerous.
- * Terminate the reflected beam so as not to irradiate the worker.
- * When the laser beam enters the filter normally, the light reflected by the filter returns to the laser light source.
- * When there is such a return light, the laser oscillation becomes unstable.
- * To prevent the return light from returning to the laser source, tilt the filter slightly.
- * The 92% transmittance filter (FND-92, MFND-92) is a flat board with no coat on both sides.
- * If the reflectivity of the no-coat surface is 4% (8% on both sides), the transmittance becomes about 92%.
