Superior transparency in the infrared spectrum: ZnSe is very clear while in the 3-twelve micron vary, which makes it ideal for use in laser beam delivery units and thermal imaging units.

One example is, if the temperature of a pipeline or container alterations abnormally, infrared thermal imaging know-how can help the staff members speedily obtain the situation and get corresponding measures to repair service it.

The index of refraction of a material is not merely dependent on the wavelength of light passing via it; It is additionally depending on the temperature, as shown in the graph to the best. This modification in index of refraction with temperature is also called the thermo-optic coefficient and is often published as dn/dT.

Hi there. I do think i found an error on this webpage: the mistake is: the y axis of the index of refraction plot doesnt appear to be right.

Thorlabs gives molded plastic, molded glass, and precision-polished aspherical lenses. Detailed beneath are the various substrates Utilized in Thorlabs' aspheric lenses. Simply click here to view Thorlabs' entire line of aspheric lenses.

Zinc Selenide (ZnSe) is ideal to be used in high electricity Co2 laser systems due to superior resistance to thermal shock, reduced absorption coefficient and lower dispersion.

Bulk and surface area absorption coefficients of zinc selenide are actually calculated by ten.6-microm laser calorimetry and exhibit a monotonic boost with temperature which is reliable in its general variety Together with the predictions of multiphonon idea, but with systematic deviations.

All the data introduced With this manuscript can be extracted be finding permission as per journal guidelines and copyrights.

Thorlabs offers a wide variety of optical substrates that are ideal for use in several purposes. The graph to the correct compares the transmission ranges of several of the commonest substrates we offer.

Small absorption:ZnSe features a lower absorption coefficient, which implies that it doesn't take up much of The sunshine more info that passes by way of it. This is important for high-ability laser programs, where the windows require to remain clear even underneath large-depth laser light-weight.

Because the thermo-optic coefficient may differ both with temperature variety and wavelength, a typical temperature variety and check wavelength are selected when reporting this specification for a cloth.

tab above. When you've got questions about a substrate not described on this website page, be sure to Get hold of Tech Assist.
