Ophir will be displaying the BeamSquared, an M2 laser beam propagation system designed to help users optimise laser performance. A robust, portable device, BeamSquared automatically measures the propagation characteristics of CW and pulsed lasers in less than a minute. It can optionally measure wavelengths above 1.8µm in manual mode, including CO2 and terahertz. BeamSquared is designed for continuous use applications, from scientific research to rapid prototyping, fabrication and machining.

FluxGage - A Photometric Test System for LED Luminaires Based on Solar Panels

This article is brought to you by: 

We present a novel photometric test system for LED luminaires. The new photometric system called 'FluxGage' uses solar panels to detect and measure light. By placing a diffuser and a black pinhole array over a solar panel we achieve a detection surface that is also an absorber. This enables the system to be the same size as the DUT (Device Under Test), as opposed to an integrating sphere, which is at least 3 times larger than the DUT. Simulations and experimental results show that this system can measure total flux with an uncertainty of 4.3%.

Ophir RM9-Thz radiometer

MKS Instruments has announced the Ophir RM9-Thz radiometer, a low noise, high sensitivity sensor for measuring low power levels of 50nW to 100mW from short pulse or CW lasers in the 0.7 to 10THz wavelength range

BeamWatch is the only non-contact beam monitoring system for high power YAG, fibre, and diode lasers used in industrial material processing applications

How is laser Power/Energy measurement affected by incidence angle?

This article is brought to you by: 

Modern laser applications demand ever-increasing accuracy in the measurement and control of the laser beam. Various types of sensors and instruments are in use today, the choice depending on the type of measurement needed. However, even given the correct choice of equipment, there are measurement conditions that can seriously affect the accuracy of the readings obtained if not correctly taken into account.
