Click the photographs under or open up the desk to the ideal to see Thorlabs’ comprehensive array of optics created from germanium.
Click on the images beneath or open the table to the best to discover Thorlabs’ entire choice of optics made out of sapphire.
Click on the images underneath or open the table to the ideal to view Thorlabs’ complete variety of optics made from N-BK7.
Silicon (Si) lenses and Home windows are a perfect choice for applications applying wavelengths while in the in the vicinity of-IR selection and areas of the mid-IR vary. Silicon provides substantial thermal conductivity and lower density, rendering it well suited for laser mirrors. Having said that, given that silicon has a solid absorption band at nine µm, It's not necessarily well suited for use with CO2 laser transmission programs.
N-F2 is really a RoHS compliant flint glass that has been engineered to possess almost identical optical properties as F2 and delivers superb general performance from the obvious and NIR spectral ranges.
Among the most vital properties in examining the optical properties of any product is the typical Digital polarizability of ions. The electronic polarizability (
Click the pictures beneath or open up the table to the proper to see Thorlabs’ entire number of optics made out of calcite.
Thinking about your information on alpha barium borate (a-BBO) You may have a typo while in the Sellmeier equation for the standard index of refraction. The initial time period you list is 2.7471. I are actually surveying on the internet information and facts for information over the coefficients, and the main price revealed is 2.
The parallel, or amazing, axis could be the axis together which transmitted mild will endure no birefringence. It is actually parallel into the optical axis with the crystal. The perpendicular, or regular, axis is perpendicular for the optical axis.
The calculated regular grain dimensions, for investigated thin movies, ranges from14.five nm to 18 nm and its values improve with increasing movie thickness from 224 nm to 633 nm. The dislocation density and lattice pressure calculated values reveal forming good quality and superior crystallinity movies. The clear-cut Evaluation proposed by Swanepoel's tactic, zinc selenide which relies upon essentially to the extremes from the interference fringes use has actually been used to compute the refractive index as well as film thickness. It had been observed that, the Swanepoel's tactic is a good solution to estimate the refractive index and movie thickness of ZnSe slim films.

Minimal absorption coefficient:ZnSe contains a minimal absorption coefficient, meaning that it does not take in Considerably of the light that passes via it, which makes it ideal for use in substantial-power laser techniques.

After discarding the supernatant, 100 µl of DMSO was placed on Each individual perfectly to dissolve the formazan crystals. The volume of dwelling cells was proportional to your formazan developed 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:
