Features
High-resolution thermal sensor for clear target identification
Featuring a 640px thermal sensor with <15 mK NETD sensitivity, the ThermTec Cyclops 635L 3.0 delivers exceptionally detailed thermal images. This high sensitivity allows it to pick up fine temperature differences, making it easier to distinguish animals from background clutter. Hunters and outdoor professionals benefit from more reliable target identification in dense bush, fog, or complete darkness.
35 mm objective lens and 2.6x optical magnification for versatile range
The 35 mm objective lens combined with 2.6x optical magnification offers an excellent balance between field of view and reach. With a maximum detection range of up to 1,800 metres, users can scan wide areas while still being able to pick up distant heat signatures. This makes the Cyclops 635L 3.0 ideal for medium to long-range spotting across open paddocks, hillsides, or large properties.
High-resolution AMOLED display for comfortable viewing
A 1600 x 1200 AMOLED display provides sharp, high-contrast visuals that make thermal details easier to interpret. The crisp image reduces eye strain during long observation sessions and helps users quickly recognise animals, people, or equipment. Combined with a 20 mm eye relief and 8 mm exit pupil, the viewing experience remains comfortable and immersive.
Integrated laser range finder for precise distance measurement
The built-in laser range finder adds accurate distance readings to the thermal image, giving shooters and spotters critical information for decision-making. Knowing the exact range to a target helps with ballistic calculations, holdover estimation, and safe shot placement. This integration streamlines the workflow in the field, eliminating the need to carry a separate rangefinder.
Lightweight mid-size design powered by 18650 battery
Weighing just 435 g and built in a mid-size form factor, the Cyclops 635L 3.0 is easy to carry on long outings and simple to operate one-handed. Its ergonomic housing and intuitive control layout suit use in cold, dark, or fast-paced situations. Powered by a widely available 18650 battery, it offers practical, field-ready power management without relying on proprietary battery systems.
