Broadband Dieletric Plate Half Mirror 30mm Diameter 400 - 700nm

PSMH-30C05-10W-550

We offer Half-Mirror optics designed for use in Ultraviolet, Visible and Infrared wavelengths. They can be used for both transmission and divergence of multi-wavelength lasers and white light sources. Ultra broadband half-mirrors are used for spectrometry applications.
◦PMH series have 4 types of ultra-broadband optics suitable for UV to IR applications.
◦PSMH series have 3 types of ultra-broadband optics for ranges from Visible to NIR, which are used for optical communication applications.
◦Dielectric multi-layer coated optics are an excellent choice for beam deviation applications because of its low absorption capabilities.
◦Its low polarization characteristic can also be applied in beam deviation with a linear polarization laser or a laser light.
◦Sigma Koki produces plate from optics that are light weight and maintains low dispersion with less aberration.
◦Both wedge and plate type mirrors are made to have “low ghosting and low interference effects”.

Guide
  • For customization, we can offer different sizes, wavelengths and deviation ratios.
  • WEB Reference Catalog Code/W3802 Please contact our Sales Division with your requests.
  • For guaranteed higher reflectance accuracy and higher transmittance optics, please contact us.
  • An arrow mark will be printed on the thick side of the wedge plate to indicate the surface of the mirror.
Remark -
Attention
  • When applying laser linear polarized light, the direction of polarization may affect the amount of reflectance and transmittance. For a divergence usage of 1:1 ratio, ensure the direction of polarization is set to 45 degrees or use a circular polarizer.
  • When a laser light transmits through the optics, the light path may shift by a few millimeters horizontally due to refraction and the thickness of the wedge plate.
  • The transmittance wavelength properties may be different if the incident angle is other than 45 degrees.
  • Please check the arrow mark on the side of the wedge plate that indicates the coated surface.
  • The phase difference of incident light cannot be preserved on light transmittance and reflectance; Please use a wave plate to compensate.
