LASER COMPONENTS' Detector Group has announced the introduction of two IR detectors, the IG19 and IA35. The IG19 is an x-InGaAs photodiode with a peak wavelength of 1.75µm, making it suitable for applications that cannot be met spectrally with a regular InGaAs photodiode. The IG19X1000S4i with a 1mm chip diameter in a TO-46 housing is the standard product.

The IA35 is a heterostructure photodiode on an InAs substrate with a relatively wide peak at 2.8µm. The curve of the spectral response can be seen in the image below. The IA35S500S4i is available now. This detector with a 0.5mm chip is designed specifically for uncooled operation and a spectral range of up to 3.5µm (20% cut-off).
