Precision Velocity Measurement: Canon Non-Contact Displacement Sensor

Non-contact sensing is invaluable in applications where measurements may be rendered unacceptably imprecise by slippage and poor speed management, or equipment or products may be damaged by contact.

IR Detectors For Thermographic Imaging

Thermographic imaging is accomplished with a camera that converts infrared radiation (IR) into a visual image that depicts temperature variations across an object or scene. This article is part 2 of a handbook by FLIR that discusses the use of IR detectors in thermographic imaging.

360° Laser Without Rotating Parts

The FLEXPOINT Radial laser module from LASER COMPONENTS can be used to precisely measure the inside of a pipe and detect irregularities as small as 50 µm. The fine, ring-shaped beam has a homogeneity of 80% and achieves an output power of 50 mW at a wavelength of 660 nm.

Photoluminescence Inspection Of Photovoltaics With SWIR Imaging

Contactless machine-vision inspection using photoluminescence (PL) imaging with shortwave infrared (SWIR) cameras can help solar cell producers improve both efficiency and quality of their photovoltaic products. Inspection of silicon bulk ingots, sliced wafers, processed layers, and complete photovoltaic cells is possible with SWIR imaging.

Industry Insights
Measuring Laser Power With The IS Series

Gentec-EO’s new IS power detectors combine the speed of photodetectors with the attenuation of integrating spheres. Combining these two technologies with Gentec-EO’s own recipe for a high damage-threshold absorber offers many advantages.

High-Sensitivity APD Optical Receiver

The Model 7511A is a high gain, low noise optical receiver employing an avalanche photodiode (APD) with a bandwidth of 35 MHz and high dynamic range capable of driving a 50 Ω load with fast saturation recovery. This note discusses the performance, function, and physical constraints of each pin.

What Are Beamsplitters?

Beamsplitters are optical components used to split incident light at a designated ratio into two separate beams. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction: cube or plate.

Two-Color Sandwich Detectors

OSI Optoelectronics offers three types of dual sandwich detectors. One is the silicon-silicon sandwich, in which one silicon photodiode is placed on top of the other. The photons of shorter wavelengths are absorbed in the top silicon and the photons of longer wavelengths penetrate deeper and are absorbed by the bottom photodiode.

High-Resolution, High-Sensitivity Digital VIS-SWIR Camera: Owl 1280

The Owl 1280 from Raptor Photonics offers visible extension from 0.6 µm to 1.7 µm to enable high-sensitivity imaging using a 1280 x 1024 InGaAs sensor. The 10-µm x 10-µm pixel pitch enables the highest resolution imaging. It will offer less than 50 electrons readout noise (rms) and, with a high intra-scene dynamic range of 69 dB, this enables simultaneous capture of bright and dark portions of a scene.
