Overview

Overview

A lightweight dual-spectrum EO/IR module pairing a 640×512, 12 μm LWIR channel with a 2560×1920 monochrome visible/NIR channel — independent 25 Hz digital outputs for system-level fusion, shared RS422 control, and a ≤70 g dual-board envelope for compact payloads.

Key Features

Key Features

Engineering profile

  • Two independent optical envelopes — the LWIR module at ≤35×35×32.2 mm and the visible module at ≤41×23×5.5 mm — let lens pairing, alignment, and downstream fusion processing be configured for the host system; both channels output simultaneously at 25 Hz under a shared RS422 link.

Key capabilities

  • Thermal channel: 640×512, 12 μm, 8–14 μm, NETD ≤60 mK
  • Visible channel: 2560×1920, 2.5 μm, monochrome visible/NIR
  • Output: independent visible and LWIR digital video — visible 8-bit; LWIR simultaneous 8-bit + 14-bit
  • Control: RS422, 115200 bps; lens options 25/40/65 mm (LWIR) and 25/40 mm (visible)

Image processing and control

  • Thermal channel supports image enhancement, polarity switching, gain/brightness control, electronic zoom, automatic/manual non-uniformity correction (shutter correction disable), OSD blanking, self-test, and version reporting.
  • Visible channel supports automatic brightness/gain/exposure, manual brightness and contrast, image enhancement, haze penetration, strong-light suppression, electronic zoom, overlays, and status reporting.

Dual-spectrum fusion

  • Independent digital outputs for both channels give host systems full flexibility for pixel-level fusion, picture-in-picture, or side-by-side display without re-encoding.
  • Genlock-aligned 25 Hz frame timing on both channels simplifies temporal registration for fusion algorithms.
  • Shared RS422 control bus allows synchronized parameter updates across thermal and visible pipelines with a single command interface.

Mechanical integration

  1. The LWIR drawing shows a 35 × 35 mm envelope, 31.5 ± 0.1 mm mounting-hole spacing and four M2 holes, 4 mm deep.
  2. The visible/NIR drawing shows a 41 × 23 mm board, 25 ± 0.1 mm and 19 ± 0.1 mm mounting dimensions, four Ø1.8 mm holes and a 5.5 mm profile.
  3. Use the detailed drawings for mounting geometry and the specification table for the overall envelope. Confirm the controlled 2D drawing, tolerances, connector clearance and lens envelope before final mechanical design.

Specifications reflect the supplied technical document. Lens, connector, mechanical, and environmental options may be finalized for the target program.
