HM-G630-LENS - 3.3X Telephoto Interchangeable Lens for G Series Thermal Imaging Cameras

The HIKMICRO HM-G630-LENS is an ultra-long-range, interchangeable 3.3X telephoto optical accessory designed to provide maximum magnification and tight pixel concentration on HIKMICRO G-series (G40, G60) and Gx1-series (G41, G41H, G61, G61H) handheld thermal imaging cameras. Featuring an advanced 80 mm focal length and a fast F1.3 aperture, this precision-engineered Germanium lens narrows the camera's perspective to a highly focused 7.5° × 5.7° on 640-resolution models and 5.6° × 4.2° on 480-resolution models. By focusing the sensor onto an incredibly narrow area, it delivers an exceptional spatial resolution (IFOV) of 0.21 mrad, allowing technicians to clearly isolate and measure tiny temperature anomalies from extreme distances with a minimum focusing distance of 3 meters. Weighing 465 grams, it maintains an industry-standard thermal measurement accuracy within ±3 °C or ±3% across extreme field temperatures ranging from -20°C to 50°C.
