LASER COMPONENTS Offers Reasonably Priced InGaAs Photodiodes with Superior Performance

LASER COMPONENTS designs and manufactures InGaAs photodiodes in house in Tempe, Arizona. The detectors include InGaAs and extended InGaAs photodiodes with the following spectral ranges:


IG17 series (500-1700nm)
IG22 series (500-2200nm)
IG26 series (500-2600nm)

Active area sizes are from 0.25mm to 3mm with standards of 0.25mm, 1mm, 2mm and 3mm. There is also a special size of 1.3mm in diameter; this unique size is small enough to be packaged into a TO-46 can, with 5.3mm base diameter, one could then drop this in-place of a 1mm InGaAs and get approximately 70% more signal, depending on your spot size of course! The D(star) detectivity is considerably better and QE is 15% higher, when compared side-by-side to equivalents to those from other key manufacturers currently on the market. Isn’t it great when you can upgrade a system by simply “dropping in” a superior pin-for-pin replacement; extending the life-span of your system without the need for a costly whole re-design, and to address those customers who demand higher performance levels - performance can often hinge on one component alone!

The prices are competitive and often lower than many currently available InGaAs photodiodes on the market!

Other key features include, lower temperature coefficient, package options including peltier cooled, ceramic mounted, SMD.

Main applications include: spectroscopy, laser monitoring, non-contact temperature measurement, tunable diode laser spectroscopy (TDLS), spectrophotometry, sorting applications and flame regulation.
