CaF2 is ideal for any demanding programs where by its substantial damage threshold, small fluorescence, and substantial homogeneity are advantageous. It truly is preferred in excimer laser purposes and commonly Employed in spectroscopy and cooled thermal imaging.
Single crystal ZnSe is offered, but just isn't frequent but has actually been described as owning lessen absorption and therefore more practical for CO2 optics.
Click on the photographs down below or open up the desk to the right to see Thorlabs’ complete selection of optics made from N-BK7.
Great mechanical Houses:ZnSe has good mechanical Houses, for instance significant hardness and toughness, making it well suited for use in applications where the Home windows can be topic to substantial pressure or effects.
N-F2 can be a RoHS compliant flint glass that's been engineered to acquire practically similar optical Homes as F2 and delivers exceptional general performance within the noticeable and NIR spectral ranges.
The place A and B are Cauchy's consistent they usually depend upon the sort of skinny movie materials. These constants ended up established from n vs . λ
The presence of a sound window at the more info entrance aperture of the air-borne FLIR can degrade the sign-to-noise ratio on account of (a) the reduction in target signal-brought on by the absorption of…
Additionally, the refractive index from the substrate (in this article glass) which calculated by the next expression:
Zerodur® is really a glass ceramic with an extremely small coefficient of thermal growth (CTE). This material is generated by Schott, and it is used to manufacture mirrors for demanding programs that are delicate to thermally-induced drift. Chemically, it is actually an inorganic, non-porous lithium aluminum silicon oxide glass ceramic that consists of evenly distributed nanoscale crystals inside of a glass section.
Large thermal steadiness:ZnSe is highly thermally stable, which makes it suited to use in higher temperature environments, like Those people encountered in industrial processes or scientific experiments.
