Thermal Observation with a 35 mm F1.0 Lens
The ThermTec Cyclops 335 SE is a handheld thermal imaging monocular for observation, night hunting, rescue operations, hiking and travel. Its 35 mm F1.0 objective lens works with a 384 x 288 thermal sensor to provide a focused combination of thermal detail, reach and portable one-handed operation.
The device starts within three seconds and uses quiet button controls with an intuitive interface, helping you move from carrying to observation without a complicated setup.
384 x 288 Thermal Imaging System
The uncooled microbolometer has a 384 x 288 resolution, 12 micrometre pixel pitch, 20 mK NETD at 300 K and an 8-14 micrometre spectral range. A 50 Hz frame rate supports smooth viewing when scanning or following movement.
Six colour palettes and Forest, Target and Outline image modes let you adapt the presentation to the scene. Automatic or manual calibration, Picture-in-Picture and heat tracking provide additional control over how thermal information is displayed.
Magnification and AI-Assisted Distance Measurement
The 35 mm F1.0 lens provides 3.3x magnification, supported by 1-4x continuous digital zoom. The field of view is 7.5 x 5.6 degrees, equivalent to 13.2 x 9.9 m at 100 m.
The supplied manual lists a detection range of up to 1,800 m for a 1.8 m human target in its comparison chart. Built-in AI-assisted distance measurement is designed to estimate distance to observed objects without adding a separate ranging unit.
AMOLED Viewing, Recording and App Control
A 0.39-inch AMOLED display with a 1024 x 768 resolution presents the thermal image through a 40 mm eye relief and 6 mm exit pupil. Dioptre adjustment of plus or minus 5 D helps users tune the eyepiece to their vision.
The Cyclops 335 SE supports photo and video recording, on-device playback and OSD recording. Real-time notifications and hotspot connectivity provide access to app-based remote control. Multiple interface languages are supported.
16-Hour Power and Field-Ready Construction
The internal rechargeable lithium-ion battery uses two 18650 cells and provides up to 16 hours of operation. The battery is not user replaceable. The Type-C connection supports battery charging and data transfer using the supplied USB cable.
The 522 g body measures 196.4 x 63.8 x 64.1 mm and carries an IP67 protection rating. Its stated operating temperature range is -20°C to +50°C.
