J22 and J23 Detector Operating Notes (0.8 to 2.6 µm)
General
The J22 and J23 series 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.
Device Options
Judson’s standard InGaAs detectors,
the J22 series, offers high reliability
and performance in the spectral
range from 0.8 µm to 1.7µm. In
addition, the J23 series extended
InGaAs detectors are available in
four cutoff options at 1.9µm, 2.2µm,
2.4µm and 2.6µm. Figure 1 shows the
typical response for the J22 and J23
series at room temperature operation.
Package Options
The J22 and J23 series are available
in standard TO packages, ceramic
sub-mounts, and bare die. We also
offer different window materials,
lenses or optical filter options. Please
refer to pages 6 and 7 for package
drawing examples.
For more demanding applications,
Judson’s team of engineers will
provide custom design services.
