High Absorbance Scanning with the PerkinElmer LAMBDA 850+ UV/Vis and LAMBDA 1050+ UV/Vis/NIR Spectrophotometers
This application note describes the procedure for high absorbance scanning with the reference grade PerkinElmer LAMBDA™ 850+ UV/Vis and LAMBDA 1050+ UV/Vis/NIR double monochromator spectrophotometers.
Measuring Absorptance and Refractive Index of Thin Films with UV/Vis/NIR
An optical coating consists of a combination of thin film layers that create interference effects used to enhance transmission or reflection properties for an optical system. In this paper we will show how the absorptance, refractive index, and film...
Health and Sanitization through UV Lighting
With increased awareness and necessity for rapid disinfection methods due to the current coronavirus pandemic, ultraviolet disinfection has become a viable method to achieve it. Determining the amount of UV energy the light source emits onto the...
Beam Profiling: A Brief Review of Best Practices
Currently, lasers that vary widely in light wavelengths and beam powers are available for many scientific, industrial, and medical applications. This article reviews the components that comprise a laser beam profiler, and describes the methods of...
Gas Purging Keeps UV Spectrophotometers Healthy
Measuring in the far-UV (FUV) 120-220 nm presents unique challenges. The high energy that makes UV light interesting can cause photochemical formation of organic films on optical surfaces. These films cause increasing, wavelength-dependent loss of...
Optical Components for SWIR Imaging
Precision Glass & Optics discusses the challenges of designing optical coatings for shortwave infrared (SWIR) imaging. Also discussed are the many advantages that SWIR imaging devices provide.
10 Steps to Choosing the Right Optical Coating
There are some critical steps you should consider when selecting an optical thin-film coating to maximize your optical systems’ performance. Small changes in requirements can often have a significant impact when evaluating performance and cost....
UVSCALE Visualizes UV light amount distribution by color density
One side of the base film has a UV light sensitive layer, with the opposite side having a white-colored layer. The light sensitive layer changes color according to the amount of UV light it receives, so the amount of light distributed on the exposed...
