The Beginner’s Guide To Laser Beam Quality And M2 Measurement

A pure Gaussian beam with a TEM00 profile and a bell-shaped curve that spreads on infinitely is never achieved. This guide introduces the concept of laser beam quality measurement with the M2 parameter, which quantifies the laser beam quality and how to measure M2 for a real laser.

Drone-Based Daylight Electroluminescence Imaging Of PV Modules Using SWIR Cameras

Electroluminescence (EL) imaging of photovoltaic (PV) solar panels provides high accuracy in detecting defects and faults. Further, the EL technique is used extensively due to a high level of detail and direct relationship to injected carrier density.

Advantages Of Multiple Band Pass Filters In Telecommunications Applications

Multi band filters help optimize price-performance balance while also conserving space, simplifying design, and improving (or offering equivalent) performance versus single-band filters.

PSD (Position Sensing Detector) Characteristics

Silicon photodetectors are commonly used for light power measurements but may also be utilized as optical position sensors. They are commonly referred to as position sensing detectors or simply PSDs. This white paper discusses the different types of PSDs and their functions in different applications.

What Is InGaAs?

InGaAs is an alloy of gallium arsenide and indium arsenide and is a III-V compound semiconductor. Creating this material is a complicated process, so why go through all the trouble? This article discusses InGaAs in detail and offers benefits for using this technology for SWIR and other imaging applications.

Optical Micromirrors Reveal The Secrets Of Cell Membranes

Progress in understanding the lipid bilayer — a two-molecule thick oily barrier that protects all living cells — has been dramatic over the past 100 years. But puzzles remain to be solved, such as how these membrane proteins navigate the oily lipid bilayer to go about their work.
