UV enhanced silicon avalance photodiode
The SUR series of siliconavalance photodiodes from LASER COMPONENTs are based on a reach through structure with high sensitivity in the DUV/UV wavelength range. Many applications particularly in the medical and biomedical fields require highly sensitive detectors at these short wavelengths for fluorescence measurements.
Wearable technology trends in the healthcare sector
Analog Devices’ Jan-Hein Broeders, Healthcare Business Development Manager for Europe, discusseshealthcare sector trends and how recent developments in technology continue to further benefit our health and improve our lives.
Wearable multi-sensor reference design with Bluetooth 5
This reference design from Texas Instruments enables a wearable, optimised saturation of peripheral capillary oxygen (SpO2) and multi-sensor, multi-wavelength optical heart rate monitor (HRM). It uses AFE4420 device, which is a single-chip, bio-sensing front end for photoplethysmography (PPG) measurements.
Long-range automotive imaging and detection at CES 2020
ON Semiconductor will have its latest LiDAR technology front-and-centre among the company’s automotive solutions at CES 2020. Recognised as a leading provider of detectors for LiDAR, the company will demonstrate the industry’s first, high-resolution, wide field-of-view (FoV) Single Photon avalanche diode (SPAD) array family designed for short-, mid- and long-range LiDAR applications.
High gain and low noise large area avalanche photodiodes
Avalanche photodiodes (APDs) are very sensitive semiconductors that exploit the photoelectric effect to convert light to electricity and are the semiconductor analogue of photomultipliers. Their spectral response depends upon the substrate used, for example, silicon detects in the ~150-1100nm region, whilst InGaAs extends to 1.7um.
IR sensors calculate colour temperature
Vishay Intertechnology has broadened its optoelectronics portfolio with RGBC-IR sensors for applications such as automatic white balancing and colour cast correction in digital cameras; automatic LCD backlight adjustment; and active monitoring of LED colour output for IoT and smart lighting.
15-bit encoder chip debuts at SPS in Nuremberg
With the new iC-RZ Series encoder chips from iC-Haus, safety encoders can be made even simpler and more compact. This is made possible by the innovative single-chip design as an optical twin encoder with a redundant safety channel.
Image sensor designed for SWIR range with record pixel density
Imec presents a new thin-film monolithic image sensor that captures light in the near-infrared (NIR) and short-wavelength infrared (SWIR). Based on a monolithic approach, the process promises an order of magnitude gain in fabrication throughput and cost compared to processing today’s conventional IR imagers, while at the same time enabling multi-megapixel resolution.
SWIR sensing capabilities expanded with InGaAs PIN photodiodes
Marktech Optoelectronics has announced the global market introduction of the Models MTPD1346D-200 and MTPD1346D-300, two large active area InGaAs PIN photodiodes, expressly designed for expanded infrared instrumentation and monitoring capabilities.
Avalanche photodiodes accelerated by internal electric field
In conventional PIN photodiodes, incoming photons create electron-hole pairs, also called charge carriers, which supply a measurable photocurrent. Avalanche photodiodes, APDs, differ from PIN detectors in that the charge carriers set free by the incoming light are accelerated by the internal electric field creating an avalanche of electron-hole pairs through impact ionisation.
