Structural Evaluation reveal the movies exhibited cubic most popular orientation along the plane (111) as well as the crystallinity and crystallite dimensions of movies improves linearly with movie thickness. The optical band hole ranges from two.sixty nine to two.eighty one eV and it is founded that it raises with film thickness. Based on the utilized Swanepoel's technique, it is achievable to estimate the optical parameters and normal thickness of your ZnSe slender movies of various thicknesses with bigger precision.
Zinc sulfide and zinc selenide immersion gratings for astronomical substantial-resolution spectroscopy: evaluation of interior attenuation of bulk resources inside the brief in the vicinity of-infrared location
Click on the pictures down below or open up the table to the correct to find out Thorlabs’ full choice of optics constructed from N-SF11.
Good day. I feel i found an mistake on this webpage: the error is: the y axis of the index of refraction plot doesnt appear to be appropriate.
The variety shown Here's with the transmission via a calcite substrate. Some goods use optical cement or other resources which will Restrict the transmission wavelength vary.
Every single products that leaves the factory is meticulously analyzed. We would want to provide you with many of the certificates needed by your aspect. For example:

When handling optics, 1 ought to usually wear gloves. This is very true when working with germanium, as dust from the material is harmful.
The fabric ZnSe deposited from the chemical vapor deposition (CVD) strategy is extensively used in substantial-electrical power CO2 laser methods because of its Remarkable heat resistance and low absorption coefficient.
