The Laser Components detector group has introduced two new IR detectors, the IG19 and IA35.
The IG19 is a new x-InGaAs photodiode with a peak wavelength of 1.75µm, making it ideal 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 IA35S500S4i is available now. This detector has a 0.5mm chip and is designed specifically for uncooled operation and a spectral range of up to 3.5µm.
