Opto Diodes' AlGaAs 850nm LED Boosts Optical Output

A new gallium aluminium arsenide night vision device may improve illumination tasks

Suited for night vision illumination tasks, Opto Diodes', OD-669-850 infrared LED illuminator produces uniform optical beam and has optical output from 800 to 1,250 mW (typ) and a peak emission wavelength of 850nm.

Spectral bandwidth at 50 percent is typically 40nm, and half-intensity beam angle is 120°. All surfaces on standard 2-lead, TO-66 electrically-isolated packagense are gold plate. Operating and storage ranges are - 40 to +100°C.

Opto Diode, a division of ITW, and a member of the ITW Photonics Group, has launched the OD-669-850 high-power AlGaAs infrared IRLED illuminator. 

Ideal for night vision illumination tasks, the infrared illuminator features ultra-high optical output, from 800 (minimum) to1250 mW (typical) and a peak emission wavelength of 850nm.

Opto Diode’s new device provides a uniform optical beam. The spectral bandwidth at 50 percent is typically 40 nm, and the half-intensity beam angle is 120 degrees. All surfaces on the standard 2-lead, TO-66 electrically-isolated package are gold plate.

The OD-669-850 IRLED illuminator’s operating and storage temperatures range from - 40 degrees C to +100 degrees C with a maximum junction temperature of 100 degrees C. 

Power dissipation (under absolute maximum ratings at 25 degrees C) is 6 W, with a continuous forward current of 370 mA, a peak forward current of 1A and reverse voltage at 5 V. The lead soldering temperature (at 1/16 in. from case for 10 seconds) is 2600C.

Opto Diode Corporation, is a member of the ITW Photonics Group and delivers standard and custom photodetectors, and reliable, high quality, standard and custom infrared and visible LEDs.

The company, with the recent acquisition of International Radiation Detectors, also designs and manufactures semiconductor radiation devices that detect photons in the UV range, X-rays, and other high energy particles. The domestic U. S. manufacturing plant includes a wafer fab and ensures delivery of volume quantities at competitive prices with short lead times. 

Opto Diodes works in a variety of industries, including test & measurement, biotechnology, medical, entertainment, military and defence, industrial, aerospace, automotive and R&D sectors.

The ITW Photonics Group was created to bring together and build on the technical expertise of three individual companies that specialise in photonics technology and span a spectrum of wavelengths.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
