Click on the pictures underneath or open the table to the proper to see Thorlabs’ full array of optics comprised of N-F2.
In laser processing purposes, it is commonly used to merge indicator gentle in the optical route. This aids improve the accuracy and effectiveness of laser processing by offering a clear sign of processing spot.
The beam combiner is used to combine the light of two wavelengths into just one optical path via transmission and reflection respectively.
ZnSe’s Excellent optical Homes, which include things like significant gentle transmission with small reduction, uniform refractive index, and low absorption of infrared gentle, enable it to be an excellent materials to be used in optical lenses of infrared thermal imagers and spectrometers.
Thanks for making contact with Thorlabs. We're getting in contact with you directly to go over the feasibility of this tailor made Answer.
The ultimate measurement of ZnSe nanocrystals by means of one particular-phase injection can be diverse via the reactivity with the Zn and Se precursors; even so, it's got a limit of
No, we don’t market shelf products. We provide customization provider according to your necessities for specific projects or makes equivalent.
, is a fabric house that characterizes the degree of transparency of a medium. The intensity transmitted by a fabric is explained because of the Beer-Lambert law:

The exponential part is called Urbach tail which implies the characteristic phenomena of absorption curve with respect to photon Vitality [46, forty seven]. By using the band tail Electrical power or Urbach Strength (Eurb) value one can estimate the dysfunction volume of the film structure. Eurb benefit could be evaluated utilizing the Urbach empirical relation [forty eight], which happens to be specified by utilize the inverses slope in the liner plot of absorption coefficient ln(
To your security, you should abide by all correct precautions, like sporting gloves when dealing with this substance and completely washing your fingers afterward. Simply click right here to down load a pdf of your MSDS for germanium.
Versions within the absorption coefficient and refractive index of bulk polycrystalline ZnSe recommend that anharmonic lattice dynamics are very important earlier mentioned 250, especially for three-phonon procedures, which include the basic TO(ensuremath Gamma ) manner.
Hall result measurements for temperatures ranging from 77 to 320 K over a series of p‐ZnSe movies grown on GaAs substrates are claimed. The ZnSe epilayers had been doped using check here a nitrogen plasma source…
