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.
The D31 and LT31 series of DLaTGS or thin LTO detectors are high-end single channel devices operating in voltage mode with an integrated JFET. Features for these devices include wide spectral coverage from UV to LWIR, a modular design, and device options for low and high speeds.

Precision positioning and motion control has vaulted forward in broadly beneficial ways. For example, submicron-resolution linear encoders now are affordably integrated into mechanisms as large as gantries and as small as matchbook-sized nanopositioners. New motor concepts abound, ranging from the familiar DC servo, stepper, and linear motors to include novel technologies like high-speed, ultra-stable resonant piezomotors and diminutive stick-slip stages with nanoscale positionability.

Atomic force microscopes (AFMs) are versatile tools for characterizing surfaces down to the sub-nanometer scale. Researchers can build their own AFMs for as little as $30,000 using off-the-shelf components such as nanopositioning stages. White Paper | By John McCauley, Ophir Photonics
Additive manufacturing allows for more customized parts using more specialized materials, and will eventually create a more localized, rapid, and agile distribution network. This white paper discusses important laser performance characteristics, how to measure them, and how to keep the laser in spec.

Operating in a climate-controlled lab or on the Martian surface, back-illuminated sCMOS detectors provide high sensitivity, high dynamic range, and low noise, even in low-light conditions. Application Note | By Yoni Groisman, Karol Sanilevitch, Roei Yiftah, Dr. Simon Rankel, Ophir Photonics
Wide, divergent beams place specific requirements on a measurement system. The apertures of conventional beam profilers are too small to collect the entire spot of large or divergent light sources, while diverging beams cannot be accurately measured with regular detectors.
