Overview

Overview

The CRYO-640-300Z is an integrated cooled MWIR zoom module: a 640×512 / 15 μm MCT focal plane with an integrated Stirling cooler sits behind 15–300 mm F/4.0 continuous-zoom optics covering 35.5° × 28.7° → 1.83° × 1.47° (±5%). Cooling buys what no uncooled core can: NETD ≤40 mK and full-frame video over HD-SDI (720p25) + CameraLink Base (100 Hz). 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 RS-422 (115200 bps) from a 28 VDC platform rail. Operating range -40℃ ~ +60℃. Inside is the M06 cooled module platform: an RS058 Stirling cryocooler with detector-level NETD of 16 mK (F/2) / 18 mK (F4) at 23 ℃, running DRC wide dynamic, 2D/3D denoising and EE edge-enhancement algorithms.
