Using 1064 nm Dispersive Raman Systems For Analysis Of Petroleum Products
6/18/2019
Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for petroleum and petroleum-based products due to their high levels of high level of photoluminescence that can overwhelm Raman signals in all visible wavelengths. This issue is now resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

Measuring Laser Power With A Pyroelectric Detector – The Basics of Energy Detectors
7/9/2020
If you are involved with pulsed lasers at any level in research, product development, final test, process control, field service or laser safety, it is important to accurately measure the energy of your laser(s). In this technical paper, you will learn about the parameters that needed to consider when selecting and using a pyroelectric detector, and about the typical steps for making good energy measurements.

What Is Heat Absorbing Float Glass?
11/21/2019
Heat Absorbing Float Glass (HAFG) is designed with the capability to typically absorb 40% of the infrared (IR) light and about 25% or more of the visible light that passes through it.

Advanced Plasma Deposition Improves Ultra Narrowband Optical Filters
6/18/2020
Narrowband filters are a critical technology for a variety of applications such as lidar (light detection and ranging), laser cleanup, chemical and gas sensing, instrumentation, and astronomy. Creating multicavity filters is a challenge for deposition process control systems. It invariably introduces undesirable ripple, resulting in signal loss in the pass band, the spectral range over which the filter has high transmittance. Alluxa uses a computer-controlled variation on the turning point method of thickness control for each individual layer, where the filter is constantly measured and variations in thickness compensated for, taking into account thickness errors associated with multiple layers.

When Failure Is Not An Option
6/11/2020
The manufacture of Intelligence, Surveillance, & Reconnaissance (ISR) optics requires a rigorous analysis of the capabilities and methods of an optical component design/manufacturing partner. Not all design/manufacturing partners are the same, and it is important that integrators elect to work in a collaborative way with companies that have the expertise, pedigree and capabilities to scale up production of components in an accurate and repeatable way.

Bus Bars And Optics
11/21/2019
A bus bar is a strip of conductive material applied to the surface of a conductively coated glass, most commonly ITO (indium tin oxide) or IMITO (index matched ITO) coatings. Abrisa applies bus bars either by thin film deposition of chrome-nickel-gold or by screen printing.
