Higher transparency: ZnSe features a higher transparency within the infrared spectrum, particularly in The three-twelve micron variety, making it perfect for use in laser beam shipping techniques and thermal imaging techniques.
You may choose-out of selling e-mail despatched by us at any time by clicking the unsubscribe url in almost any promoting electronic mail you get.
ZnSe is applied broadly for IR elements, windows and lenses, and for spectroscopic ATR prisms. Zinc Selenide is one of the components of choice for CO2 laser optics working at 10.six microns.
Click on the images beneath or open up the desk to the ideal to find out Thorlabs’ comprehensive selection of optics made from silicon.
Also called the V-quantity, the Abbe amount can be an optical home that quantifies a fabric's dispersion, or variation in refractive index with regard to wavelength. It is described with the equation
Each and every product that leaves the manufacturing facility is diligently tested. We wish to provide you with each of the certificates expected by your aspect. Such as:
One of the most widespread utilizes for selenium is in glass output the red tint that it lends to glass neutralizes environmentally friendly or yellow tints from impurities while in the glass resources. Selenium was found out and initially isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin from the identify Selenium arises from the Greek phrase "Selênê," indicating moon.
Safety Details Sheet In line with Regulation (EC) No. 1907/2006 (Get to). The above mentioned details is thought being suitable but won't purport being all inclusive and shall be utilized only like a guide. The knowledge With this document is based to the existing state of our knowledge and is also relevant for the product or service regarding appropriate basic safety safeguards.
Zerodur® is a glass ceramic with an especially small coefficient of thermal expansion (CTE). This content is manufactured by Schott, and is used to manufacture mirrors for demanding applications which are sensitive to thermally-induced drift. Chemically, it's an inorganic, non-porous lithium aluminum silicon oxide glass ceramic that includes evenly distributed nanoscale crystals inside a glass stage.

ZnSe Home windows may also be Employed in thermal imaging methods, in which They may be used to transmit the IR light emitted by objects and develop an image. They're also Utilized in spectroscopy read more techniques, where by These are made use of to gather and analyze light-weight from molecular vibrations.
The elastic anisotropy can be described the universal elastic anisotropy index AU and that is developed by Ostoja–Starzewski44 for crystal with any symmetry. The AU could be published as follows:
Distinct interest is paid on the impact of impurities and intrinsic defects to the optical functionality of ZnSe.
Soon after discarding the supernatant, a hundred µl of DMSO was placed on each very well to dissolve the formazan crystals. The volume of residing cells was proportional for the formazan generated in DMSO, which was quantified at 490 nm utilizing a microplate reader (ELISA MAT2000, DRG Instruments, Marburg, Germany). Mobile viability was resolute as percentages as follows:
