Overview

Overview

The CRYO-640-500Z is an integrated cooled MWIR zoom module: a 640×512 / 15 μm MCT focal plane with an integrated Stirling cooler sits behind 30–500 mm F/5.5 continuous-zoom optics covering 18.2° × 14.6° → 1.0° × 0.8° (±5%). Cooling buys what no uncooled core can: NETD ≤0.3 K @ 12 cy/mrad (NFOV) and full-frame video over HD-SDI + PAL. The module carries the field-proven function set — auto and manual focus with per-step focus memory, movable crosshair with position memory, white/black hot polarity, 8 palettes, ×2/×4 e-zoom, defocus and background NUC, image enhancement and power-on / periodic BIT — controlled over CAN 2.0 + RS-422 from a 28 VDC platform rail. Operating range -40℃ ~ +60℃.
