Optical Parallel BK7 20x20mm λ

OPB-20S05-1-5

Optical Parallels are precision substrates polished on both sides with excellent surface quality and surface flatness. These substrates can be used with thin film coatings to make custom windows and beamsplitters.
◦The Optical Parallels are available in BK7 for visible and infrared wavelength range.
◦The high accuracy of the substrate parallels does not change the angle of the transmitted beam when you insert it parallel to the substrate perpendicular to the optical path of the laser.
◦The high surface precision substrate can also be used instead of a Newton test plate.

  • We also offer the fabrication of the substrates with coating per your specific specifications, contact our Sales Division with your request.
Remark -
Attention
  • Transmissions losses due to reflection off the front and rear surfaces of the Parallel flat substrate can be minimized by coating the surfaces. Consult our Sales Division for anti-reflection coatings suitable for your application.
  • A data sheet for accuracy guarantee of the surface flatness is not included with the product. If you need a guarantee sheet of the flatness data, Please contact our Sales Division for a quotation.
