LASEROPTIK stocks substrates for coatings in the wavelength range from 120 nm to 50 µm. Only the highest grade materials are used in the production of the components.
Nevertheless most optics are custom made at unique requirements and drawings. So please feel free to send your individual specifications.
All substrates are manufactured at high quality specifications in order to keep critical optical properties as scattering, absorption or beam deviation at a minimum. Besides flatness and roughness, the surface imperfections are another critical parameter.
Listed on the following pages LASEROPTIK stocks a selection of UV- and IR-transmitting substrates for fast delivery. A brief characterization of the substrates is given for every type.
Most orders of our customers can be met with FS-UV and FS-IR. For these we offer a large number of plane and curved substrates.
In our standard sizes we can offer Fluorides as MgF2 and CaF2. For CaF2 we offer four different qualities (VUV-grade for 157 nm, UV-grade for 193 nm or 248 nm and VIS-IR quality).
For applications with an absorption free range up to 4 µm, Sapphire or undoped YAG is recommended. Both materials are very hard and withstand temperatures up to 1.000 °C as well as high pressure.
ZnSe is a standard material for use from 500 nm up to 22 µm, because of its broad transmission range, its low absorption and scatter.
For each stock substrate material and for the most common wavelengths we list the
Material refractive indices.
Most orders of our customers can be met with FS-UV and FS-IR. For these we offer a large number of different substrate types:
Wedged, large wedges, elliptical
Zero lenses, cavity lenses
Cylindrical lenses, prisms
Premium and super-polished substrates
Plane parallels, etalons
In our standard sizes we also can offer
MgF2, CaF2, ZnSe, Sapphire, YAG
For CaF2 four different qualities are available: VUV-grade for 157 nm, UV-grade for 193 nm or 248 nm and VIS-IR quality.
