Pulsar's thermal lenses allow are a series of quick and interchangeable lenses that are compatible with the Helion 2 series of thermal imaging monoculars. These lenses will modify the magnification, field of view and detection range of your monocular. They are easily attached via a waterproof bayonet mounting. Please note that lenses should only be interchanged in clean spaces and away from areas of wind to prevent dust and dirt covering the thermal sensor.
