By now, most thermal users are familiar with the sensor resolution of a device e.g. 640x480, and also the pixel pitch e.g. 17µm. The improvement of these new Series 2 devices concentrates on a key specification of thermal sensor technology – the NETD value.
The NETD (Noise Equivalent of Temperature Differential), expressed in millikelvins (mK) is one of the most important parameters for thermal sensors as it describes their sensitivity. The lower the NETD value, the higher the sensitivity.
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).
