Optics and Optical Coatings

Optical coating consists of a combination of thin layers. These produce interfering effects that are used to improve the transmission or reflection characteristics of a system. The behavior of an optical coating depends on the number of lambda/4 layers, the thickness of the individual layers, and the differences between the refractive indexes of the individual layers. The most common coatings for precision optics are antireflection coatings (AR), highly reflective coatings (HR), beam splitter coatings, and filter coatings.



Hybrid Cube Half Mirrors

OSE-HBCH

Low polarization cube half mirrors can be used for broadband visible and infrared light. The hybrid coating is a special combination of metallic and dielectric multilayers resulting in a low polarizing and broadband coating.
Chromium Cube Half Mirrors

OSE-CSCH

Chromium cube half mirrors consist of two rectangular prisms. One of them is coated with chromium on the hypotenuse surface.
Dielectric Cube Half Mirrors

OSE-CSMH

Dielectric cube half mirrors consist of two right-angled prisms. One of them is coated with a dielectric multilayer partial reflection layer on the hypotenuse surface.
Laser Line Plate Half Mirrors

OSE-PSMH-LL

Laser line plate mirrors are plate beamsplitters optically coated on the front side of optical parallels or wedge-shaped substrates with a dielectric multilayer coating.

Broadband Dielectric Half Mirrors

OSE-PSMH

These half mirrors have 3 types of ultra-wideband optics for ranges from visibile to NIR, which are used for optical communication applications.
Thin Plate Beamsplitter

OSE-MPSMH

These thin beam splitters can be inserted into an optical light path without beam shift or chromatic dispersion for any light transmission application.
Chromium Plate Half Mirrors

OSE-PSCH

Chrome plate half mirrors are plate beamsplitters coated with chrome on the front side of optical parallels or wedge-shaped substrates.
