Product Details

Product Model: 61-6930-54
Product Brand: SIGMAKOKI CO., LTD.

Features

  • A high quality window ***d to allow light to pass through the inside of an airtight container or the other side of a bulkhead.
  • Since the transmittance is increased according to the wavelength of the YAG laser, it can be ***d as a laser window.
  • There are two types: the parallel plane type, in which the angle of the transmitted beam does not change even if the window plate is inserted vertically in the optical path of the laser, and the wedge type, in which the interference between the front and the back side is small.
  • Since the low scattering substrate is coated with high laser resistance, it can be ***d for high energy pulsed lasers.
  • Windows for fundamental (1064 nm), double (532 nm), triple (355 nm), and quadruple (266 nm) YAG lasers are available.
  • * When the wedge type is inserted into the optical path of the laser beam, the beam is inclined by about 0.5°.
  • * Transmitted light loss is higher when using at wavelengths other than the adaptive wavelength.
  • * Transmittance may be reduced when using at a large incidence angle.
  • * Using a high energy laser with a narrow squeeze may ca*** damage.
  • * Be sure that the laser beam does not exceed the laser capacity before ***.
  • * Where the wedge board is thickest, an arrow is marked in the direction of the surface.
