Optical sensors are electronic components designed to detect and convert incident light rays into electrical signals. These components are useful for measuring the intensity of incident light and converting it into a form readable by an integrated measuring device, depending on the sensor type. This article outlines the principles of operation of optical sensors, optical sensor types, considerations for optical sensor selection, and key applications.
Pyreos, the world’s first supplier of integrated digital SMD pyroelectric sensor subsystems for gas, flame, plus materials analysis applications, and supplier of the world’s smallest SMD pyroelectric detector, announces that it has expanded its refrigerant gas detection range and is now supplying extended-wavelength variants of its ultra-low power, low cost ezPyroTM digital SMD sensors optimized for the latest refrigerant gasses.
Pyreos has chalked up a significant design win with Safe Zone Technologies Inc which supplies gunfire detection systems for indoor spaces.In this application ezPyro infrared detectors are used for high-speed muzzle-flash detection and analysis. The Pyreos sensor is integrated into a very small networked multi-sensor solution which is easily installed within public buildings such as retail stores, schools, and offices. Pyreos began shipping ezPyro sensor subsystems in volume to Safe Zone in late 2019. The design-in cycle lasted just four months and benefitted from Pyreos’ extensive range of reference boards, APIs, engineering application support, and comprehensive design information. ezPyro’s analysis speed, low cost and small form factor were all key factors in Safe Zone’s selection.
Pyreos has announced the appointment of two new distributors to increase its commercial presence in Asia. Pyreos sales to its established Asian distribution network grew by 50% in 2020 and make up around a third of revenues. The company aims to build on this success by joining forces with I&C Micro Systems to access more markets in South Korea, and Pidtek to extend its coverage of China.
Chips 4 Light extends its UV LED Portfolio and offers a highly effective UV LED in 265 nm for sterilization and disinfection applications. This UV LED developed by Stanley Electric Co., Ltd, proofs in a first scientific study in collaboration with Yamaguchi University in Japan to minimize the germ formation also for viruses such as the Corona SARS CoV-2. Generally, is the emission in this wavelength spectrum suitable for all kinds of surface, air and water disinfection. Further test and studies will be succeeded.
Premstaetten, Austria (February 11, 2021) — ams (SIX: AMS), a leading worldwide supplier of high-performance sensor solutions, today launches the 4LS series, adding new faster and higher resolution line scan image sensors to its broad family of sensors for machine-vision applications. Use of cameras equipped with 4LS sensors will help operators of the latest smart factories to maintain the highest standards of quality control while increasing the volume of production output.

Columbia Research Laboratories has introduced a new sensor designed to accurately measure strain on curved mounting surfaces. Series DT3747 sensors are customized to measure circumferential strain around the diameter of the surface to which it is mounted. Featuring the accuracy, ruggedness, and ease of installation found in Columbia’s flight-qualified Series DTD284, DT3747 models are available to compensate materials commonly used in aircraft structural fabrication. Similar devices have been utilized to monitor rocket motor expansion. They can also be used in many industrial and military applications involving pipe expansion measurements, explosive body applications, aircraft surface load, and engine monitoring of all types.
Premstaetten, Austria (December 2, 2020) — ams (SIX: AMS), a leading worldwide supplier of high performance sensor solutions, today announced the launch of the AS6221, the world’s most accurate digital temperature sensor.The AS6221 achieves measurement accuracy of ±0.09°C, over a temperature range from 20°C to 42°C, making it ideal for the measurement of human body or skin temperature. No competing digital temperature sensor on the market today can achieve accuracy better than ±0.10°C. The digital temperature sensor AS6221 is housed in a WLCSP package with a footprint of just 1.5mm x 1mm, and draws 6µA at an output data rate of 4Hz. Stand-by current is just 0.1µA.
Premstaetten, Austria (October 20, 2020) — ams (SIX: AMS), a leading worldwide supplier of high performance sensor solutions, takes smartphone optical sensor miniaturization to a new level with the introduction of the TMD2712, the world’s smallest integrated ambient light sensor (ALS) and proximity sensor module in a miniature 1mm x 2mm footprint.

Teledyne e2v’s CCD image sensor is headed to Mars on NASA’s Perseverance Rover. Its mission? To investigate rock samples on the red planet for past signs of life.
Premstaetten, Austria (29 July 2020) — ams (SIX: AMS), a leading worldwide supplier of high performance sensor solutions, reports record revenues for the second quarter, up 13% year-on-year and at the mid-point of the expectation range, with strong adjusted operating profitability at the top end of the expectation range. This growth was driven by demand in ams’ consumer business, even with the ongoing Covid-19 pandemic and its macro-economic and end market impact which resulted in muted automotive and industrial demand. Despite these factors ams expects a very good third quarter with revenues of USD 530-570 million and continued strong profitability resulting in an adjusted operating (EBIT) margin of 21-24%.
I, like most people these days, do a lot of things differently since social distancing came into being during the coronavirus pandemic. I wonder which tech-based ones will stick. Some are really good ideas borne out of necessity; others can go the way of Covid-19, when it’s finally off the radar.
