Product Details

Product Model: 61-6882-42
Product Brand: SIGMAKOKI CO., LTD.

Features

  • Cold mirrors reflect only visible light and transmit infrared light.
  • It can be ***d to separate light rays, such as sunlight, into visible and infrared (hot) rays.
  • Since it ***s a dielectric multilayer film with no absorption and glass with good infrared transmission, the glass will not break even if it is installed near a light source, even if a sudden temperature change occurs in the filter.
  • It can also be ***d to efficiently extract only infrared light.
  • It can also be ***d as a near-infrared filter by changing the angle of incidence.
  • * Cannot be ***d for high energy pulsed laser.
  • * High power laser mirror (TFMHP) is available for pulse laser.
  • * There is no anti-reflection film on the back.
  • * Allow visible light to enter from the dielectric multilayer film coat side.
  • * Light-of-light loss of about 10% occurs when the light is injected from the back side.
  • * Ghosting of the statue may occur.
  • * If a heat-absorbing object is placed on the back of the filter, the reflected light may be mixed with infrared light emitted from the absorber.
  • * The filter also transmits infrared rays coming from the back side, so please open the back side of the filter to let out the infrared rays.
  • Using the projector at an angle other than 45 degrees can ca*** infrared light to be mixed with the reflected light.
