Guide TB1260LS Thermal Clip-On

The Guide TB1260LS Thermal Clip-On combines ultra-high-resolution thermal imaging, integrated laser rangefinding and extended detection performance in a powerful clip-on platform designed for use with compatible daytime optics.

Featuring an impressive 1280×1024 12μm thermal sensor with 15mK NETD thermal sensitivity, the TB1260LS delivers exceptional thermal detail and strong target definition across demanding conditions. Its 60mm objective lens provides a detection range of up to 3200 metres, while the integrated 1200m in-lens laser rangefinder delivers fast and accurate distance measurement directly through the device.

Guide's ApexVision S1 image processing architecture, Hyper-Light enhancement and G-Zero shutterless technology work together to improve clarity, contrast and image smoothness across changing environments.

With a 0.5-inch 1600×1200 AMOLED display, 1× clip-on configuration, dual replaceable 18650 battery system, Wi-Fi connectivity, recording functionality and IP68 protection, the TB1260LS delivers premium thermal performance in a versatile clip-on format.

ApexVision S1 Image Processing

The TB1260LS is powered by Guide's ApexVision S1 image processing architecture, developed to maximise image clarity, detail and overall thermal performance.

Advanced processing works alongside the ultra-high-resolution detector to improve image definition, enhance contrast and reduce unwanted thermal noise.

This is particularly valuable at longer distances, where retaining fine detail around heat signatures and surrounding terrain becomes increasingly important.

Ultra-High-Resolution 1280×1024 Thermal Sensor

At the heart of the Guide TB1260LS is a 1280×1024 thermal detector with a 12μm pixel pitch.

With more than 1.3 million thermal pixels, the sensor provides substantially more image detail than lower-resolution thermal detectors, helping users distinguish finer features across the thermal scene.

Combined with 15mK NETD thermal sensitivity, the detector can recognise subtle temperature differences, helping maintain useful image quality in challenging weather and low thermal-contrast environments.

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

60mm Lens & 3200m Detection Range

The TB1260LS features a 60mm objective lens, designed to deliver strong longer-range thermal performance.

Paired with the 1280×1024 thermal detector, the optical system provides a stated detection range of up to 3200 metres.

This makes the TB1260LS particularly suited to users who require high-resolution thermal observation across large properties and open terrain while maintaining the benefits of a clip-on configuration.

Integrated 1200m In-Lens Laser Rangefinder

The TB1260LS incorporates a 1200m laser rangefinder integrated directly into the objective lens assembly.

Positioning the LRF close to the optical axis helps reduce parallax between the ranging system and viewed image while keeping the overall device design streamlined.

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× Clip-On Configuration

The Guide TB1260LS uses a 1× optical configuration, allowing it to add thermal imaging capability to a compatible daytime optic without introducing significant magnification of its own.

This helps preserve the familiar viewing characteristics, reticle and controls of the host optic while adding ultra-high-resolution thermal imaging and integrated ranging.

Optimised for Compatible Day Optics

The TB 2.0 platform is designed to integrate with compatible daytime optics while maintaining precise alignment.

Fine zeroing adjustment of approximately 1.22cm at 100 metres allows accurate setup with the host optic.

This configuration enables users to retain their existing day optic while adding thermal capability in front of the optical system.

G-Zero Shutterless Technology

The TB1260LS features Guide G-Zero shutterless technology, designed to eliminate the regular image freezing associated with conventional shutter-based calibration.

This provides smoother and more continuous thermal viewing while also reducing calibration noise during operation.

Hyper-Light Image Processing

Guide's Hyper-Light algorithm works alongside ApexVision S1 and the high-sensitivity detector to enhance image clarity, contrast and finer thermal detail.

The processing system helps reduce image noise and improve definition, particularly during longer-range observation or when thermal contrast across the scene is relatively low.

1600×1200 AMOLED Display

The Guide TB1260LS features a 0.5-inch AMOLED display with 1600×1200 resolution, providing a detailed presentation of the high-resolution thermal image.

Available thermal palettes include White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot and Sepia, allowing the image presentation to be adapted to different conditions and viewing preferences.

Wide Field of View

Despite its substantial 60mm objective lens and long detection range, the TB1260LS provides a field of view of approximately 14.6° × 11.0°, or 25 × 19 metres at 100 metres.

This broad viewing area complements the ultra-high-resolution sensor, providing strong situational awareness while scanning larger areas.

Dual Replaceable 18650 Battery System

The TB1260LS is powered by two replaceable 18650 batteries, providing up to 6 hours of operating time.

The replaceable battery configuration allows compatible spare batteries to be carried for extended field sessions.

The device also supports USB-C external power and USB 2.0 connectivity, providing additional flexibility when a suitable power source is available.

Video, Audio & Wi-Fi Connectivity

The Guide TB1260LS supports video and audio recording, allowing thermal observations to be captured directly through the device.

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

IP68 Weather Protection

With an IP68 protection rating, the TB1260LS is designed for 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 reliable operation across a broad range of climates and field conditions.
