The J22 and J23 Series detectors are high performance InGaAs detectors operating over the spectral range from 0.8µm to 2.6µm. These detectors provide fast rise time, uniformity of response, excellent sensitivity and long term reliability for a wide range of applications. For enhanced performance or temperature stability of response near the cutoff wavelength, Judson offers a variety of thermoelectrically cooled detector options.
