All curves are shown for standard combinations of coatings and substrates, listed as tab. "Standard Components", below.
Standard values of partial reflectors (output couplers, beam splitters and beam samplers) are described and listed as "Partial Reflectors", below.
Prices for complete coating runs are listed under tab. "Coatings", below.
In combination with substrate prices, higher quantities can be calculated. Please contact LASEROPTIK for price information on special designs, other substrate sizes, customer supplied substrates. Please specify your request and add a short comment.

Partial reflectors in stock see Partial Reflectors

Example:
1 piece HR 1064 nm / 0°, N-BK7, Ř 38 x 6.35 mm, planoconcave, radius of curvature...170.– € (Euro)

PR 0° Partial reflectors and output coupler (OC)
for YAG, Alexandrite and Ruby lasers are available in the usual reflectivities.
AR coatings on the back prevent feedback to the laser cavity. With wedged substrates AR coatings can be dispensed, because the beam of the uncoated side is deflected off axis. To prevent energy losses, our wedged output couplers have AR coatings, too. see: table below
For Variable Output Couplers OC see: GOC (Gradient Output Couplers) in menu section "Variable"

BS 45° Beamsplitter
can be used for separation of a part by reflection and conversely for combining of two beams. AR coating on the second side improves transmission and prevents internally reflected ghost images due to interferences with the reflecting side.
Displacement of the transmitted beam depends on refractive index and thickness of the substrate.
Splitting ratio depends on polarization of the incident beam. Reflectivity in S polarization is always higher than for P, as can be seen in tab. below and in the curves.
The reflectivity of S- and P-components is very sensitive to the angle of incidence (AOI), whereas the ratio for unpolarized light (or randomly polarized) is nearly constant up to AOI 65° as can be seen for the 50%-BS 1064 nm, 45°.
see: table below
Angular variable Beamsplitter see: VA (Variable Attenuators) in menu section "Variable"

AR 45° = Beamsampler
are used for monitoring of the laser by splitting off a small, but achromatic part of the beam and direct it to a detector.
Depending on incident polarization, front surface reflectances from 1% to 10% can be attained with BK7 at 45° incidence.
see: table below

A spectrometer curve is supplied to all components (no additional fee).

Beamsplitters and beamsamplers are mainly in stock as round plates Ř 25 x 6.35 mm.
Most of the listed reflectivities are also available as rectangular Suprasil plates 50 x 27 x 1.5 mm
(with BS+AR € 250.–).
