Click the pictures down below or open the table to the appropriate to view Thorlabs’ comprehensive selection of optics made from germanium.
(nu), is really a evaluate of just how much a material contracts while in the perpendicular direction because of stretching, or conversely, the amount of a material expands while in the direction perpendicular to the utilized drive due to its compression. Imagine stretching a rubber band and observing the band grow to be thinner; as you proceed to extend it farther, the thinness also raises.
To be able to receive the bulk modulus B and shear modulus G, the Hill model is applied, which normally takes the arithmetic ordinary in the Voigt40 and Reuss models41. For cubic technique, Hill shear modulus G and bulk modulus B are taken in the form of42:
Great mechanical Attributes:ZnSe has great mechanical Houses, such as high hardness and toughness, rendering it suited to use in applications where by the windows can be subject matter to large anxiety or influence.
We established incredibly minimal MOQ for personalisation initiatives. But naturally, cost is going to be quoted according to the quantity to cover our generation Price.
Moduli which were calculated rather then calculated are observed while in the specification table for every applicable substrate.
