Ultra Broadband Dieletric Plate Half Mirror 25.4mm 400 - 2000nm

PMH-25.4C03-10-4/20

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.

Details

◦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.
