Thanks for achieving out to Thorlabs, we're hunting into this concept and I might be in touch with you to Permit you know how the dialogue progresses.
Knoop hardness (HK) is often a evaluate of a material's mechanical hardness and is particularly most commonly presented for brittle products. Knoop hardness is tested by pressing a pyramidal diamond-formed indenter into a cloth sample and examining the resulting indentation in the material.

Documents relevant to the goods that you have purchased in past times happen to be gathered during the Document Library on your usefulness.
It can be deposited as a skinny movie by chemical vapour deposition tactics together with MOVPE and vacuum evaporation. References[edit]
The structural and elastic Attributes of ZnSe for both B3 and B1 buildings beneath different pressures are investigated by way of the primary-rules aircraft-wave pseudopotential method based on density purposeful concept (DFT). From the same old issue of equal enthalpies, the period changeover of ZnSe from B3 to B1 happens at the force of 14.eighty five GPa. According to the received elastic constants, the stress dependence of the majority modulus, shear modulus and Youthful’s modulus of ZnSe are calculated and talked about intimately.
Inside the petrochemical field, infrared thermal imaging technology may be used to detect temperature variations in pipelines and containers, so as to detect and deal with potential complications in time.
ZnSe is a comparatively smooth substance which has a Knoop Hardness of 120 which is at risk of scratches and is not suggested to be used in harsh environments.
When managing optics, a person should really always wear gloves. This really is very true when dealing with zinc selenide, as It's really a dangerous product.
High thermal steadiness:ZnSe is highly thermally steady, more info making it suitable for use in superior temperature environments, like These encountered in industrial procedures or scientific experiments.

Popular applications consist of infrared and FTIR spectrophotometry. KBr is comfortable and hygroscopic, so optical factors should be protected from extra moisture including substantial humidity environments.
The THz band is located amongst microwaves and optics to the electromagnetic spectrum. This locale influences the combination of microwave and optical systems Utilized in the THz band.
