Dielectric HR&PR coating

Dielectric HR&PR coating


A dielectric coating consisting of alternating layers of quarter-wave film of a higher refractive index and lower refractive index than the substrate. Such coatings can be made very specific to a reflected wavelength or, by varying the layers’ thickness or film index, spread over a wide wavelength interval including high reflection coating(HR) and partial reflective coating(PR).

Coating Type Properties and Application
High Reflection Dielectric High Reflective Coatings Provide high reflectance over a broad bandwidth, and is ideal for a tunable laser or in white light applications
Partial Reflection Narrow Band Provide 50% reflection and transmission at an angle of 45° incidence for a single wavelength. Perfect for beamsplitters application. Transmission/reflection (T/R) ratio of 20/80, or others for Beamsplitter is available upon request.
Broadband Over a wide bandwidth provides 50% reflection and transmission. LaserStates can also provide coatings with different R/T ratios at and specific angle of incident.
