Window High Power Anti-reflected Coated 266nm 25.4mm Diameter

WSQNAHP-25.4C03-10-266

main product photo
These optical windows have high-quality and may be used when light is passed through the opposite side of the partition or in the vacuum chamber. Since the windows have anti-reflection coatings the transmittance is increased so they can be used as a window for laser irradiation windows and the observation of the sample.
◦When you insert an window perpendicular to the optical path of the laser, the angle of the transmitted beam is not changed.
◦Since the high laser threshold coating is applied on the low scattering substrate, it can be used for the high-energy pulsed laser.

Standard Coatings Available No
Guide
  • We also offer AR coatings in accordance to your wavelength selection.
  • Product sizes and wedges which are not mentioned on our website or in this catalog are available, please ask our Sales Division.
Remark -
Attention
  • When wedge type windows are inserted into the optical path of the laser beam, the beam tilt of about 0.5° is expected.
  • When used at a wavelength other than the designed wavelength, the loss of transmitted light will be higher.
  • When used at a large incident angle, the transmittance may decrease. We can provide AR coatings with highest transmission at a specific angle of incidence upon request.
  • When using a high-energy laser with thin diameter, there is a possibility that damage may occur. Before using, make sure that the laser beam does not exceed the laser damage threshold.
  • Wedged substrates are marked with an arrow toward the direction of front surface at the thickest point.
