Optical Window BK7 25.4mm Diameter Anti-reflection Coated 633 - 1064nm

WBMA-25.4C03-10-IR1

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.
◦By anti-reflection coating with a dielectric multi-layer, it is reduced to less than 1% to 4% reflection loss of the glass surface.
◦Since we are using the high quality material, the image will not be distorted by the transmission of the glass, and the laser beam is not diffused.
◦When you insert an window perpendicular to the optical path of the laser, the angle of the transmitted beam will not be changed.

Guide
  • Anti-reflection coatings are also available at your specified wavelength.
  • In addition to the products described on our website and in the catalog other sizes and wedged windows are available.
Remark -
Attention
  • When using a laser which has a large diameter, there is a possibility that very little interference fringes will be observed in the luminance distribution of the transmitted light. To avoid this effect of the interference fringes, we provide wedged substrates.
  • When used at wavelengths other than the specified wavelength region, the loss of transmittance increases slightly.
  • When used in a large incident angle, there is a possibility that the transmittance decreases. Also available are anti-reflection coating to increase the transmittance at a particular angle of incidence.
