◦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”.
