CaF2 is ideal for any demanding applications where by its substantial injury threshold, reduced fluorescence, and superior homogeneity are effective. It is well known in excimer laser programs and regularly used in spectroscopy and cooled thermal imaging.

Click on the images underneath or open up the table to the proper to view Thorlabs’ complete selection of optics made from sapphire.

The index of refraction of a cloth is not just depending on the wavelength of light passing via it; It is usually dependent on the temperature, as demonstrated while in the graph to the right. This alteration in index of refraction with temperature is often known as the thermo-optic coefficient and is often created as dn/dT.

The improve in index of refraction with wavelength is known as dispersion and can be clearly seen in the graph to the correct, which exhibits the variation in n

This graph reveals the measured transmission of an AR-coated zinc selenide window at typical incidence. The shaded area denotes the AR coating range, about which Ravg < 1.0%. Performance outside of the specified selection is not confirmed and varies from ton to whole lot.

Reaction from Mike at Thorlabs: Thank your for your feed-back. You will be appropriate, the index of refraction plot for our calcite is incorrect. We now have now updated this to match what might be offered utilizing the Sellmeier equation about the web page.

An assessment is offered of several recently developed strategies for measuring low absorption losses in optical rnaterials with Exclusive emphasis on how thermocouple and photoacoustic calorimetry can be utilized to ascertain both of those bulk and surface area absorption at the same time.

Yttrium Orthovanadate (YVO4) is a optimistic uniaxial crystal that's mostly employed for polarization optics. It has a significant birefringence and a wide transparency selection that extends into your infrared, rendering it perfect for IR polarizers.

This graph demonstrates the measured transmission of an website AR-coated zinc selenide window at ordinary incidence. The shaded location denotes the AR coating array, in excess of which Ravg < 3.five%. General performance beyond the specified range is not confirmed and differs from ton to whole lot.

American Factors presents regular and custom made Proportions of zinc selenide products according to purchaser requirements. All higher purity resources are subjected to qualitative and quantitative Assessment via atomic spectroscopy, x-ray diffraction, scanning electron microscopy, and BET surface area location Examination, between other systems, to make sure the elemental composition and structural Houses of each and every products rigorously adhere to standards. Please ask for a quotation higher than to acquire pricing facts dependant on your technical specs.
