Quadrant Arrays HgCdTe
| Typical Applications: |
|
The HgCdTe detectors can be fabricated in Quadrant Arrays for scanning, tracking and positioning systems. The quadrant arrays require a common lead between the four elements in either X or Y direction. This is normally wider than the minimum separation in order to handle the bias current of all four detectors. Typical specifications are given for the 2mm to 12.5 mm region, however detectors are normally built as custom device arrays for the entire 1mm to 25mm range and can be fabricated with custom packages and using various cooling techniques.
InfraRed Associates, Inc. also has extensive experience in fabricating
arrays from 2 to 128 elements. Multi-element arrays can be fabricated in a
large variety of custom configurations including linear, staggered, offset,
cross, etc. Elements as small as 25mm x 25mm with 12mm spacing can be provided
with uniform radiometric characteristics. The arrays may vary in wavelength
response from 1mm to 25mm and can be fabricated with custom electronics to
minimize the output format.
