HM-G620-LENS - 2X Telephoto Interchangeable Lens for G Series Thermal Imaging Cameras

The HIKMICRO HM-G620-LENS is a professional-grade, interchangeable 2X telephoto optical accessory designed to significantly narrow the field of view (FOV) and increase the magnification on HIKMICRO G-series (G40, G60) and Gx1-series (G41, G41H, G61, G61H) handheld thermal imaging cameras. Featuring a 50 mm focal length and a fast F1.3 aperture, this precision-engineered Germanium lens narrows the camera's perspective to a concentrated 12.3° × 9.3° on 640-resolution models and 9.3° × 7.0° on 480-resolution models. By concentrating the pixels onto a smaller area, it delivers an outstanding spatial resolution (IFOV) of 0.34 mrad, enabling crisp, highly detailed thermal tracking of tiny components from long distances with a minimum focusing distance of 1 to 2 meters. Weighing approximately 308 grams, it maintains strict thermal accuracy within ±3 °C or ±3% across extreme field conditions, ensuring exact temperature evaluation on hard-to-reach assets.
