The Teledyne FLIR Merlin NIR is a high-performance InGaAs infrared camera designed for near-infrared imaging across 0.9 – 1.7 µm. It delivers 320 × 256 pixel imagery at 60 Hz with thermoelectric stabilization and exceptional operability exceeding 99.9%. The camera operates in both radiometric and non-radiometric configurations, with factory-calibrated models providing temperature measurement accuracy of ±2° or ±2%. Variable integration time (1 µs to 16.5 ms) and dual gain modes enable a total dynamic range of 69 dB—four orders of magnitude above single-mode operation. Solid-state InGaAs detectors withstand laser damage thresholds greater than 1 W/cm² with no image retention at intensities exceeding 10 W/cm².
