Package Options
TE-Cooled Devices: Large-area detectors are available
mounted on a 1-stage or 2-stage thermoelectric (TE) cooler.
Cooling increases shunt resistance (see Figure 2) thereby
reducing noise for increased sensitivity. Typical detector
temperature is -10°C with a 1-stage TE cooler or -35°C
using a 2-stage cooler. A TE-cooler option can be specified
by adding the extension -TC (1-stage cooler) or -DTC (2stage cooler) to the standard part number (see ordering
guide). More information is available from the "TC-Series
Cooled Photodiodes" datasheet from PerkinElmer
Optoelectronics Canada.

Detector and Pre-Amplifier: Large-area InGaAs detectors are
also available integrated with a preamplifier and TE-cooler. The
HTE-series features large-area InGaAs detectors with a high
gain hybrid transimpedence amplifier mounted on a 2-stage TE
cooler. TE-cooling maximizes sensitivity and stabilizes op-amp
offset and output characteristics. This provides an easy-to-use
high sensitivity detector platform optimized for good temperature
stability over a wide operating temperature range. More
information is available from the HTE-series datasheet. The
standard HTE-2642 incorporates a C30642E chip.
