x-InGaAs and InAs Photodiodes - Now Expanded to MIR

LASER COMPONENTS Detector Group has announced two new IR detectors, the IG19 and IA35.

IG19: the IG19 is a new x-InGaAs photodiode with a peak wavelength of 1.75 µm, making it ideal for applications that cannot be met spectrally with a regular InGaAs photodiode. The IG19X1000S4i with a 1 mm chip diameter in a TO-46 housing is the standard product.

IA35: the IA35 is a heterostructure photodiode on an InAs substrate with a relatively wide peak at 2.8 µm. The curve of the spectral response can be seen in the image shown.

The IA35S500S4i is available now. This detector with a 0.5 mm chip is designed specifically for uncooled operation and a spectral range of up to 3.5 µm (20% cut-off).
