In existing Helion, Trail and Accolade series models the NETD value was sub 60mK. The new <40mK sensor, exclusively manufactured by ULIS for Pulsar puts Pulsar devices at the forefront of the market with the devices all featuring a better image in conditions where there is a low-temperature difference such as during rainfall, fog or cold mornings. These environmental conditions are the most difficult for thermal imagers and this new sensor will provide a clearer image for users.
The Helion 2 XP50 series features a 640x480 17µm thermal sensor and a F50/1.2 lens that provides a detection range of up to 1800m for a deer-sized object. The lens is interchangeable and can be replaced with an F38/1.2 lens (PUL-79054 F38 Thermal Len) allowing the device to satisfy the need to have a spotter with a wide field of view (with the 38mm lens fitted) or by switching the lens, a high magnification unit (with a 50mm lens fitted).
