The characterization of optical components using the Cary Deep UV spectrophotometer and 'VW' specular reflectance accessory
This document details the characterization of optical components using the Cary Deep UV spectrophotometer and the 'VW' specular reflectance accessory. Measurements were conducted in an inert atmosphere within a nitrogen-purged glovebox over a wavelength range of 140 to 250 nm.
The study demonstrates the instrument's ability to acquire high-quality UV spectra down to 140 nm without vacuum systems. It compares the reflectance properties of three magnesium fluoride coated optical components, highlighting differences attributable to various coating methods.
| Wavelength range | 140 to 250 nm |
|---|---|
| Oxygen limit | less than 1 ppm |
| Grating specification | Dual 1200 line/mm |
The samples were characterized over the wavelength range 140 to 250 nm.
Measurements are made in an inert atmosphere using a nitrogen-purged glovebox.
The 'VW' specular reflectance accessory is used to acquire and compare spectra.
