Novel Thin-Film Coating Design Separates/Combines Polarization In One Optic

Bedford, NH – With a newly designed thin-film polarizing coating, LASER COMPONENTS offers a single optical component that simultaneously separates the polarizations of three wavelengths. It not only separates the three different wavelengths but can also be used to distinguish between lasers of the same wavelength.

Manufactured and designed according to customer specifications, this optic combines linearly polarized laser beams from several sources of differing wavelengths and separates the unpolarized beams into polarized light simultaneously.

The trichroid thin-film polarizer was designed for an angle of incidence of 45 degrees and exhibits excellent reflection properties for red (640 nm), green (520 nm) and blue (450 nm) light for s-polarization, while p-polarized energy is transmitted with high efficiency. “This three-in-one coating design requires compact and extremely accurate coating layers with very demanding physical thickness tolerances, states Huyen Vu, sales director. Our state-of-the-art Ion Beam Sputtering (IBS) coating technology enables exactly that”. If you are in the market for a high performance, high quality thin-film polarizer that provides demanding specifications and optimum technology, look no further than LASER COMPONENTS.
