The Liemke Merlin-13 VOx Ceramic Thermal Imaging Monocular has set the standard for the ultra-compact thermal imaging monocular. The Merlin-13 only weighs 5.29 ounces and is currently the smallest thermal imaging lens on the market, but despite its small size, it is remarkably durable with its certified IP67 waterproofing. It features a 13mm fixed focus front lens used in conjunction with a 12µ pixel pitch that yields a detection range of 650 meters and a field of view of 24 meters at 100 meters.
