I. NLIR256 Infrared Thermal Module | Compact Uncooled Core

Highly Integrated 256×192 Micro Thermal Engine for Handheld and Portable Platforms

The NLIR256 represents a major advancement in compact thermographic engineering, functioning as a highly optimized, cost-efficient infrared thermal module designed for handheld security, portable inspection equipment, and weight-sensitive smart devices. Built around our innovative 12μm Wafer-Level Packaging (WLP) VOx detector and paired with a proprietary second-generation IR ISP processor, this module delivers crisp thermal performance while strictly complying with the most rigorous SWaP-C constraints.

This 256×192 resolution infrared core yields sharp imagery with an NETD thermal sensitivity of ≤40mK (@25℃, F#1.0), which allows engineers to easily spot thermal anomalies or track targets in absolute darkness. Equipped with multi-interface output logic—including MIPI, DVP, and USB 2.0 digital video pipelines alongside analog CVBS video—the NLIR256 provides rapid, flexible integration with diverse AI platforms, making it an incredibly agile building block for modern portable vision networks.
