Guide TU650LS Thermal Scope with LRF

The Guide TU650LS Thermal Scope with LRF is a high-resolution, long-range thermal optic designed for users who need detailed imaging, extended detection capability and integrated distance measurement in one rugged platform.

Featuring a 640×512 12μm thermal sensor with 15mK NETD thermal sensitivity, the TU650LS delivers detailed thermal imagery and strong target definition across challenging conditions. Its 50mm objective lens provides a detection range of up to 2600 metres, while the integrated 1200m in-lens laser rangefinder delivers fast, accurate distance readings directly through the scope.

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

A large 1.03-inch 2560×2560 AMOLED display, 3.7×–29.6× magnification, up to 14 hours of battery operation, Wi-Fi connectivity and IP68 protection complete a powerful long-range thermal optic designed for demanding field use.

Includes quick-release scope mount.

ApexVision S1 Image Processing

The TU650LS features Guide's ApexVision S1 image processing architecture, developed to enhance thermal image clarity, definition and overall viewing performance.

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

This is particularly valuable during longer-range observation, where maintaining definition around distant heat signatures and surrounding terrain becomes increasingly important.

High-Resolution 640×512 12μm Thermal Sensor

At the heart of the Guide TU650LS 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 TU650LS is capable of detecting 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 TU650LS features a 50mm objective lens, giving it strong performance for extended-range thermal observation.

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

This makes the TU650LS particularly well suited to users who prioritise observation across large properties, open terrain and other environments where longer-distance thermal detection is important.

3.7×–29.6× Magnification

The Guide TU650LS provides 3.7× base magnification, giving users a detailed initial view for medium- and longer-range observation.

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

The combination of high sensor resolution and extended magnification makes the TU650LS a particularly capable option for observing subjects at distance.

Integrated 1200m In-Lens Laser Rangefinder

A key feature of the TU650LS is its 1200m laser rangefinder integrated directly into the objective lens assembly.

Positioning the LRF close to the optical axis helps minimise parallax between the ranging system and the viewed image while maintaining a streamlined overall design.

The integrated rangefinder allows users to locate a thermal signature and obtain distance information through the same device, eliminating the need to switch to a separate handheld rangefinder.

1.03" 2560×2560 AMOLED Display

The Guide TU650LS features a large 1.03-inch AMOLED display with 2560×2560 resolution, providing a highly detailed and immersive viewing experience.

The high-resolution display complements the 640×512 thermal detector and ApexVision image processing system, helping present fine thermal detail clearly during extended observation.

Available thermal palettes include 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.

Hyper-Light Image Processing

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

The processing system is designed to provide a clearer, more defined image when environmental conditions make thermal contrast more difficult to distinguish.

Shutterless 3.0 Technology

The TU650LS 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.

Dual-Battery System

The TU650LS uses a multi-battery configuration consisting of two built-in 18650 batteries and one external replaceable 18650 battery.

Together, the system provides up to 14 hours of operating time, making the scope suitable for extended field sessions.

The external battery can be replaced when required, while USB-C charging and USB 2.0 connectivity provide convenient access to power and data functions.

Video, Audio & Wi-Fi Connectivity

The Guide TU650LS supports video and audio recording, allowing thermal observations to be captured directly through the scope.

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

IP68 Weather Protection

With an IP68 protection rating, the TU650LS is designed for use in demanding outdoor environments where exposure to dust, water and changing weather conditions may occur.

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

Quick-Release Scope Mount Included

The Guide TU650LS includes a quick-release scope mount, providing a convenient mounting solution straight out of the box.

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