GS-FPA-640×512 640×512 25μm Cooled Area‑array InGaAs Detector TE1/TE2 28-pin MDIP
1. Introduction
GS-FPA640*512 is a cooled InGaAs area-array focal-plane detector responding within 0.9-1.7 μm short-wave infrared waveband. It features 640*512 resolution with 25 μm pixel pitch and 16 mm *12.8 mm photosensitive target surface.
The sensor supports TE1 and TE2 two-grade TEC cooling configuration with low dark-current ≤0.2 pA. It achieves quantum efficiency ≥70%, fill factor＞99% and effective pixel rate＞99%, crosstalk＜1%. Dual-gain readout provides adjustable full-well-capacity for different signal intensity. Housed in 28-pin MDIP Kovar hermetic package, maximum pixel readout rate reaches 10 MHz. Suitable for solar-cell inspection, semiconductor testing, hyperspectral imaging and other scientific-grade infrared applications.
