It is also known as a flat-field focusing mirror or linear lens. As opposed to common focusing lenses that concentrate the focal location on 1 place, the scanning lens disperses the laser beam to multiple details over the scanning area or workpiece, creating a uniform concentrated spot of the laser beam in the whole marking airplane.
Click on the photographs beneath or open the desk to the best to discover Thorlabs’ comprehensive choice of optics produced from ZnSe.
The CO2 laser beam expander is also called a partial reflector, which might mirror a Portion of the entire laser Vitality again towards the resonator, and let the other Component of the Strength transmit and output for processing.
Great mechanical Homes:ZnSe has excellent mechanical Qualities, for example large hardness and toughness, rendering it ideal for use in purposes in which the Home windows could be issue to higher stress or effects.
By furnishing your facts and clicking ‘Subscribe’, you choose-in to receiving periodic e mail promoting communications from Coherent Corp. and realize that your individual info will probably be processed in accordance with our Privateness Policy and that our Conditions use.
Based on the Fantastic house of ZnSe product itself and our fantastic production abilities of ZnSe lenses and windows as well as our better precision of technical specs and reliable high quality.
Bulk and floor absorption coefficients of zinc selenide are already measured by 10.6-microm laser calorimetry and show a monotonic raise with temperature that is definitely reliable in its normal sort Along with the predictions of multiphonon concept, but with systematic deviations.
Looking at your info on alpha barium borate (a-BBO) You could have a typo within the Sellmeier equation for the everyday index of refraction. The 1st phrase you list is two.7471. I have already been surveying on-line information and facts for data around the coefficients, and the first worth shown is 2.
The first difference involving graphene-dependent batteries and reliable-state batteries lies within the composition of either electrode. Even though the cathode is often altered, carbon allotropes can also be here used in fabricating anodes.

Limited transmission outside of the infrared spectrum:ZnSe just isn't as clear during the visible spectrum, making it considerably less well suited for use in optical systems in which seen gentle transmission is necessary.
We also supply laser windows, which have AR coatings centered all-around generally utilised laser wavelengths, and Brewster Home windows, which are created to remove P-polarized mirrored gentle.
tab for transmission and reflectance plots). Zinc selenide includes a transmission band broader than silicon and germanium.
Hall effect measurements for temperatures starting from 77 to 320 K on a number of p‐ZnSe movies developed on GaAs substrates are described. The ZnSe epilayers have been doped using a nitrogen plasma resource…
