Vishay Semiconductors has created an interesting reflectance proximity detector (VCNL4000) that includes an infrared (IR) LED and a photodetector. A second sensor in the same package measures ambient ...

Marktech’s new 2.6µm InGaAs photodiode detectors in a hermetic TO metal can packages, One of Several New InGaAs PIN Photodiode Innovations Launching in 2023. The spectral responsivity of Marktech's ...

Mid-infrared spectroscopy is one of the main techniques for chemical sensing. Molecules can be identified through their unique pattern of absorption lines, which give rise to the ‘fingerprint region’ ...

Rosemont, Ill. — TT electronics OPTEK Technology unveils a high-sensitivity infrared (IR) detector capable of fast response times. The OP570 series silicon phototransistor is housed in a miniature ...

Ever wonder how to calculate revolutions per minute using a microcontroller? This project shows you how by purposing an IR emitter and detector and a computer fan. As the fan blades spin they disrupt ...

To measure how fast something spins, most of us will reach for a tachometer without thinking much about how it works. Tachometers are often found in cars to measure engine RPM, but handheld units can ...

Vishay Intertechnology, Inc. today broadened its optoelectronics portfolio with the release of a new 850 nm infrared emitter featuring a parabolic lens for a very narrow ± 3° angle of half intensity.

Key Features: High output emitter, 0.04Watts/cm2 Fast pulse rates, up to 180Hz with 50% modulation depth Easy to apply with integrated electronics in 14 pin IC Lower overall system costs Compact with ...
