Opto Diode Introduces Wide Temperature Range IR Emitter
24 to 28mW GaAlAs LED operates from -65 to 150degC
Opto Diode Corporation has introduced a wide temperature range infrared (IR) emitter designed for demanding military and industrial markets.
The GaAlAs OD-850WHT IR LED features typical optical power output ranges from 24 to 28mW, a wide emission angle, and operates at extended temperature ranges from -65 to 150degC. The emitter has peak emission of 850nm and an optical half intensity beam angle of 80 degrees. With no internal coatings, the device can operate without heat sinking and without derating to 80degC.
For military applications, the extended temperature range of the OD-850WHT allows simplified thermal design for night vision, aircraft, and vehicle light markers for covert operations.
The device's thermal improvements also suit high temperature industrial photoelectric controls used in petroleum refining, chemical processing, and power generation.
According to the company, improvements in thermal design reduces overall cost for monitoring and inspection systems for heaters and furnaces so increased productivity, reduced fuel consumption and emissions, can be achieved.
The device is available in a hermetically-sealed, standard two-lead TO-46 package. All surfaces on Opto Diode's high-temperature infrared emitter are gold-plated for added durability.
Opto Diode Corporation is an ITW company based in Camarillo, California.
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
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.
