Signal-To-Noise Ratio vs Calibration Uncertainty vs Repeatability In Laser Power And Energy Measurement

It is common to search for the measurement solution with the lowest uncertainty of measurement for laser processes involved in demanding applications such as medical device manufacturing or aerospace parts manufacturing, where traceability is key to a production line. Calibration uncertainty of a laser power meter or energy meter may not be the only specification needed checked. Repeatability, linearity and noise equivalent power or energy are other specifications that must be checked out as well. Let’s make it simple! This article will help you select the right detector for your laser measurement needs and quickly.

Photonic Array Device Assembly

PI’s Fast Multichannel Photonic Alignment (FMPA) technology was introduced in 2016.  It quickly amassed prestigious honors like the R&D 100 Award and the Lightwave Innovations Award for its revolutionary ability to perform multiple alignment processes in parallel.

The Application Of WDM Channel Skip Filters

Channel skip filters enable precision band splitting in telecommunications options, offering improved performance over edge pass filters at a cost adaptable to any project budget.

Phantom Goes To MIT: A Series Of Case Studies

High-speed photography is alive and well at the Massachusetts Institute of Technology (MIT) Edgerton Center. The Center makes high-speed imaging equipment available to students to help further their education in science and engineering.

High Speed, Digital SWIR Camera: Owl 320 HS

The Owl 320 HS from Raptor Photonics offers the fastest frame rates available in the Owl camera line-up (up to 349 Hz in full frame resolution), perfect for high speed VIS-SWIR applications within the 0.4 µm – 1.7 µm range. With Region of Interest (ROI) control, faster frame rates in the kHz region are achievable by setting smaller ROIs.

Pyroelectric DLaTGS Detectors

Laser Components offer pyroelectric detectors designed to create an electric signal due to temperature changes in the chip. Deuterated Lanthanum α Alanine doped TriGlycine Sulphate (DLaTGS) detectors specifically exhibit the most effective pyroelectric effect known. Although there are many other possible uses, the major application for these detectors is FTIR spectroscopy.

High Resolution, Ultra-Sensitive Digital EMCCD Camera: Hawk 252

The Hawk 252 is a cooled HD ultra-sensitive digital EMCCD camera offering back-illuminated EMCCD technology for enabling ultimate sensitivity imaging (< 50μlux). The camera features high QE of greater than 95% at 600 nm, and GEN III image intensifier performance and enhanced blue response from 180 nm for low light UV with visible detection.

IR Lightweight Zoom Lenses: 680389, 680314, 680386

Ophir's family of LightIR lenses are compact yet offer high-performing features. While optimized for stabilized payloads, the 680389, 680314, and 680386 products are also suitable for a wide range of applications.
