Thermal imaging monocular optics military grade


The SPI WASP represents the line of the most technologically advanced thermal imaging monoculars currently existing on the market. Based on US advanced high sensitivity LWIR Microbolometer engine and made of high-grade aircraft aluminum alloy the unit guarantees durability and outstanding performance even to the most sophisticated users. This uncooled, long-wave infrared, magnified thermal imaging camera by SPI is designed for fulfilling of both day and night missions irrespective of the environment and weather factors, while a wide variety of objective lenses (25 mm, 50 mm, and 75 mm) enables the operator to use the device as both a compact, pocket-sized thermal imaging monocular, or as a long-range observation tool. The WASP thermal imaging monocular can be easily connected to extended battery pack to increase operational time. Optional WiFi module for live video streaming and recording is also available.
