The IR series uncooled infrared modules are advanced thermal imaging solutions developed by CHENGDU NEWTRON TECHNOLOGY CO., LTD. Designed with self-developed 12µm WLP-packaged high-refresh-rate detectors and 2nd-generation infrared ISP chips, these modules deliver exceptional performance across a range of demanding applications.

With resolutions of 640×512, 384×288, and 256×192, the IR series supports a wide operating temperature of -40°C to +85°C and a temperature measurement range of -20°C to +550°C. Their compact size, lightweight design, and low power consumption make them ideal for SWaP (Size, Weight, Power/Price) applications.

Key Features

  • High refresh rate across all series

  • Standard non-uniformity correction algorithm

  • High-quality imaging with sharp detail

  • Cost-effective and power-efficient

Application Scenarios

  • Drone Search: Electro-optical pods

  • Portable Devices: Handheld outdoor equipment, helmet-mounted night vision

  • Security & Fire Inspection: Industrial monitoring, perimeter scanning, inspection robots, fire warning systems, firefighting helmets

  • Smart Integration: Assisted driving, smart home appliances

Product Selection Guide

Lens Parameters

Note1: Detection, recognition, and identification distances are estimated based on the Johnson criteria, with a pedestrian (1.8×0.5×0.3m) as the target.

Note2: Weight refers to the lens only. Total weight includes the lens, module body, connector cable, and optional USB components.

Note3: FOV data is provided in Section 2.1

Note4: Depth of field refers to the maximum clarity range under fixed focus (e.g., glued or screw-fixed), not the adjustable focus range (typically 0.3m to ∞).
