PC-LN2-19-1x1-VFP-NW-50

Product catalog summary

Introduction
This document is a preliminary datasheet for the PC-LN2-19-1x1-VFP-NW-50, a HgCdTe photoconductive infrared detector optimized for operation at 77 K, provided by VIGO Photonics S.A.

Features

Active element material is optimized for operation at 77 K.
Specially designed flatpack package without a window for easy self-assembly in LN2 metal dewars.
Optional assembly in LN2 metal dewars (Kadel KR163-FSMA2, Kadel KR-323) by VIGO Photonics upon request.
Optional assembly of a temperature sensor.
Active area dimension of 0.25 mm × 0.25 mm available upon request.
Other acceptance angle values available upon request.

Applications

FTIR spectroscopy.

Series Configuration
The detector is configured for LN2 cooling at 77 K, with no temperature sensor, a 1x1 mm active area, no optical immersion, a flatpack package, and a 50-degree acceptance angle.

Specifications

Peak wavelength: 16.0 µm
Cut-off wavelength: ≥20.0 µm
Detectivity: 1.0×10¹⁰ cm·Hz^1/2/W
Voltage responsivity: 170 V/W
Resistance: 25 Ω
Bias current: 15 mA

Mechanical Layout and Signal Output
Includes LN2-VFP(2p), PC detector technical drawing.

Absolute Maximum Ratings

Ambient operating temperature: -20 to 30 °C (operation above 30°C may increase LN2 consumption).
Storage temperature: -20 to 50 °C.
Storage humidity: 10 to 90% (no dew condensation).
Maximum incident optical power density: 100 W/cm² for CW or pulses >1 µs, 1 MW/cm² for pulses <1 µs.
Maximum bias current: 25 mA.

Exceeding these ratings may cause permanent damage and affect device reliability.
