Infrared Emitting Diodes
Light Emitting Diodes (LEDs) are solid-state P-N junction devices that emit light when forward biased. An IRED is an Infrared Emitting Diode, a term specifically applied to PerkinElmer IR Emitters. Unlike incandescent lamps, which emit light over a very broad range of wavelengths, LEDs emit light over such a narrow bandwidth that they appear to be emitting a single “color”. Their small size, long operating lifetimes, low power consumption, compatibility with solid-state drive circuitry, and relatively low cost make LEDs the preferred light source in many applications.

A new range of broadband IR LEDs is now distributed by Scitec Instruments. Typical emission bandwidth is 0.5 mm and power levels at 10s to 100s of microwatts depending on duty cycle etc. The devices now offered are superior to the prior ones because:
They are packaged in a 'screw package' that allows easy heat sinking and thus higher drive power and higher optical power output

Infrared LED (IRED)
An exceptional technology base positions Opnext as a frontrunner in the industrial field. Opnext provides a high performance line-up of Infrared Light Emitting Diodes (Infrared LED) based on a wealth of tried and tested technologies, such as high 40mW output and collimated optical output.
Infrared LED
High output is achieved through the use of the unique domed-chip formation technology, and an excellent beam shape is provided by precision lens (package) design technology.
There is a selection of suitable products for use as the encoder light source in NC machine tools and robots, and the light source for ophthalmoscopes and position detection equipment.
