CaF2 is perfect for any demanding applications where by its high damage threshold, lower fluorescence, and superior homogeneity are beneficial. It is popular in excimer laser apps and usually Utilized in spectroscopy and cooled thermal imaging.
(nu), is often a measure of the amount a cloth contracts during the perpendicular route due to stretching, or conversely, the amount of a cloth expands from the course perpendicular to the used power because of its compression. Visualize stretching a rubber band and watching the band turn out to be thinner; when you continue to extend it farther, the thinness also increases.
When dealing with optics, 1 really should usually dress in gloves. This is especially true when working with barium fluoride as It's really a hazardous product. For your personal security, remember to dress in gloves Each time dealing with BaF2 and completely clean your hands afterwards. Click here to down load a pdf in the MSDS for BaF2.
Suitability of gloves needs to be decided the two by material and good quality, the latter of which can vary by company.
The assortment shown here is for that transmission by way of a calcite substrate. Some goods use optical cement or other materials that may Restrict the transmission wavelength assortment.
Moduli that were calculated as opposed to calculated are famous within the specification desk For each and every relevant substrate.

, is a cloth property that characterizes the diploma of transparency of a medium. The intensity transmitted by way of a material is described because of the Beer-Lambert law:
Determine 4 describes the actions of B/G ratio for the two B3 and B1 constructions from the investigated pressure selection. The acquired B/G ratio for polycrystalline ZnSe are all larger than 1.seventy five, implying which the polycrystal usually complete in a ductile fashion. Figure four additional illustrates that the rise of hydrostatic strain tends to improve the ductile actions of ZnSe. The effect of strain to the ductile of B3 ZnSe is much larger than that within the ductile of B1 ZnSe.
Click on the pictures underneath or open the desk to the correct to find out Thorlabs’ comprehensive choice of optics comprised of α-BBO.

tab for transmission and reflectance plots). Zinc selenide provides a transmission band broader than silicon and germanium.
This substrate scratches conveniently and should be taken care of with treatment. When handling optics, normally don gloves. This is certainly especially true when dealing with zinc selenide, as it is a hazardous material.
