Guide TU650S Thermal Scope

The Guide TU650S Thermal Scope is a high-resolution, long-range thermal optic designed for users who demand detailed imaging, extended detection capability and reliable performance in challenging field conditions.

Featuring a 640×512 12μm thermal sensor with 15mK NETD thermal sensitivity, the TU650S delivers detailed thermal imagery with strong target definition. Its 50mm objective lens provides a detection range of up to 2600 metres, while a broad 3.7×–29.6× magnification range provides the flexibility to observe and examine distant heat signatures.

Guide's next-generation ApexVision S1 image processing architecture and Hyper-Light algorithm enhance image clarity, contrast and fine detail, while Shutterless 3.0 technology provides smooth thermal viewing with minimal interruption.

A large 1.03-inch 2560×2560 AMOLED display provides an exceptionally detailed viewing experience, while up to 14 hours of battery operation, Wi-Fi connectivity, recording functionality and an IP68 protection rating make the TU650S a highly capable long-range thermal platform.

Includes quick-release scope mount.

ApexVision S1 Image Processing

The TU650S features Guide's ApexVision S1 image processing architecture, designed to enhance thermal image clarity, definition and overall viewing performance.

Advanced processing works alongside the high-resolution 640×512 detector to improve image contrast, reduce unwanted noise and preserve finer thermal detail.

At longer observation distances, this combination helps maintain greater definition around detected heat signatures and surrounding terrain.

High-Resolution 640×512 12μm Thermal Sensor

At the heart of the Guide TU650S is a 640×512 thermal detector with a 12μm pixel pitch.

The high-resolution sensor provides increased detail across the thermal image, helping users distinguish subjects and environmental features with greater definition.

Combined with 15mK NETD thermal sensitivity, the sensor can detect subtle temperature differences within a scene, helping maintain useful image quality in challenging weather and low thermal-contrast conditions.

A 50Hz frame rate provides smooth imagery while scanning or observing moving subjects.

50mm Lens & 2600m Detection Range

The TU650S features a powerful 50mm objective lens, providing enhanced performance for longer-distance thermal observation.

Paired with the 640×512 detector, the optical system provides a stated detection range of up to 2600 metres.

The longer focal length and high-resolution sensor make the TU650S particularly suited to users who prioritise detection and observation across large properties and open terrain.

3.7×–29.6× Magnification

The Guide TU650S provides 3.7× base magnification, delivering a detailed initial view suited to medium- and longer-distance observation.

Magnification extends up to 29.6×, providing substantial flexibility when closer examination of distant thermal signatures is required.

The high-resolution 640×512 detector helps retain greater usable image detail as digital magnification is increased.

Long-Range Field of View

The TU650S provides a field of view of approximately 8.8° × 7.0°, or 15 × 12 metres at 100 metres.

This provides a useful balance between longer-range magnification and maintaining enough surrounding terrain within the image for scanning and observation.

Hyper-Light Image Processing

Guide's Hyper-Light algorithm works alongside ApexVision S1 to enhance image contrast, reduce noise and improve finer thermal details.

This processing is designed to produce a clearer and more defined thermal image, particularly in environments where thermal contrast is reduced.

Shutterless 3.0 Technology

The TU650S incorporates Guide Shutterless 3.0 technology, designed to minimise image freezing and audible clicking associated with conventional thermal calibration cycles.

This provides smoother, more continuous thermal viewing during normal operation.

A shutter module is retained for startup calibration and operation under extreme temperature conditions to help maintain optimal image quality.

Large 2560×2560 AMOLED Display

One of the standout features of the Guide TU650S is its large 1.03-inch AMOLED display with 2560×2560 resolution.

The high-resolution display provides a detailed and immersive viewing experience that complements the 640×512 thermal detector and ApexVision image processing system.

The larger display is particularly beneficial during extended observation and when examining finer details at higher magnification.

Multiple thermal palettes are available, including White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot and Sepia.

A -5 to +5 diopter adjustment allows the viewing system to be fine-tuned for individual users.

Ergonomic Focus & Zoom Controls

The TU650S features an ergonomic control arrangement designed around intuitive access to focus, zoom and commonly used functions.

The focus wheel, zoom control and button layout allow adjustments to be made quickly while maintaining a comfortable operating position.

Up to 14 Hours Battery Runtime

The Guide TU650S offers an impressive up to 14 hours of operating time, making it well suited to extended field sessions.

Its power system consists of two built-in 18650 batteries plus one external 18650 battery, providing substantial operating capacity.

The scope also supports USB-C charging and USB 2.0 connectivity, providing convenient access to external power and data transfer.

Video, Audio & Wi-Fi Connectivity

The Guide TU650S supports video and audio recording, allowing thermal observations to be captured directly through the device.

Built-in Wi-Fi functionality provides wireless connectivity with compatible external devices for supported viewing, sharing and device functions.

IP68 Weather Protection

The TU650S carries an IP68 protection rating, providing strong protection against dust and water exposure during demanding outdoor use.

Its specified operating temperature range of -20°C to 50°C provides versatility across a broad range of environmental conditions.

Quick-Release Scope Mount Included

The Guide TU650S includes a quick-release scope mount, providing a mounting solution straight out of the box.

Quick-release mount scope tube torque: less than 2.5N·m / 22.13 in-lb.
