Classically, visible laser detection is an application that would only be suited to silicon photodiodes. However, Laser Components UK has announced that, for designers seeking devices with greater temperature stability, its panchromatic InGaAs photodoides come up trumps.

The robust, hermetic assembly of Laser Components' fibre-coupled Avalanche PhotoDiodes (APDs) and Pulsed Laser Diodes (PLDs) make the devices effective for many applications. For example, high-power PLDs (as the laser source) and suitable low-noise InGaAs APDs are used for distributed temperature sensing applications, and Si Geiger-mode APDs are used for photon counting.

A sensor for the Correlated ColourTemperature (CCT) of light, which enables designers of portable devices such as smartphones and tablets to implement enhanced display management and brightness control, has been introduced by ams. Alongside the traditional red, green and blue (RGB) colour sensor channels, the TCS3490 features an infra-red (IR) measurement channel for the detection of the IR signature of ambient light sources.

LASER COMPONENTS has released a new iteration of the tremendously successful LCSA and LCIA avalanche photodiodes, called the A-CUBE. These highly miniaturised modules have an edge length of only 40mm and can be used for fW optical power detection with a direct RF output and high bandwidth capabilities.

Vishay Intertechnology is broadening its optoelectronics portfolio with the introduction of twoautomotive-grade, high-speed, silicon PIN photodiodes, in top-view, surface-mount packages measuring 5x4x0.9mm. Offering a large sensitive area of 7.5mm2, the VEMD5010X01 and VEMD5110X01 provide high radiant sensitivity with a reverse light current of 48µA and a very low dark current of 2nA for automotive, industrial, consumer, and medical applica...

ams has released a family of intelligent sensors that integrate six key sensing functions, including gesture detection and Mobeam barcode emulation. The TMG399x product family is suited for touchless gesture control and display management in smartphones, tablets and many other consumer electronics.

Providing a large amount of optical performance in a small amount of space, the MICROmote photoelectric sensors have been released by Balluff. Offered with a separate electronic processor, the sensors feature miniaturised LEDs, photodiodes and phototransistors. A patented manufacturing process, which has enabled high optical precision, was used to produce the sensors.

PREMA Semiconductor develops silicon photodiodes with adapted spectral sensitivities. While light with short wavelengths is absorbed by the initial microns, the penetration depth for light with longer wavelengths varies a lot. Therefore, the spectral sensitivity of photodiodes can individually be adapted by the position of the pn‑junction.

Targeting photo detection in applications such as light curtains, light barriers, metering systems, switches and rain and sun sensors, Vishay has announced two automotive-grade high-speed silicon PIN photodiodes. The VEMD6010X01 and VEMD6110X01 provide a high reverse light current of 9.5µA (three times that of previously released devices, according to Vishay) and a very low dark current of 1nA.

Atelectronica 2014,Vishay Intertechnology will be exhibiting a range of it'scapacitors, resistors, inductors, diodes, power ICs, optoelectronics and power MOSFETs. The event takes place on the 11th to 14th November 2014 at the Munich Trade Fair Centre in Munich, Germany, and the company will be in its main booth A5.142-143 and Automotive Innovation booth A6.A13-A15.
