GOYOJO TE Series 400×300 Thermal Imaging Monocular – 25mm F1.0

The GOYOJO TE Series 400×300 Thermal Imaging Monocular is a compact handheld infrared observation device designed for wildlife observation, property inspection, farm monitoring, outdoor exploration, search-support activities and general heat-source detection.

Featuring a 400 × 300 thermal detector with 12 μm pixel pitch and 25 mK thermal sensitivity, the TE Series delivers detailed thermal imagery by detecting differences in infrared energy rather than relying on visible light.

A 25mm F1.0 objective lens provides a listed 11.0° × 8.2° field of view, while the high-resolution 0.32-inch 800 × 600 AMOLED display presents thermal imagery with excellent contrast and clarity. The device provides a listed thermal detection distance of up to approximately 1,300 metres (1,400 yards).

The built-in rechargeable battery provides up to approximately six hours of operation, while 20W quick-charging support provides convenient charging between outdoor observation sessions. An IP67-rated enclosure adds protection for outdoor use.

400 × 300 Thermal Imaging

At the centre of the GOYOJO TE Series is a 400 × 300 thermal detector with a 12 μm pixel pitch.

The thermal detector senses infrared energy emitted by people, animals, machinery, buildings and other objects and converts temperature differences into a visible thermal image.

Unlike conventional digital cameras, thermal imaging does not require visible illumination to detect heat signatures, making the device suitable for both daytime and night-time thermal observation.

25 mK Thermal Sensitivity

The TE Series features a listed NETD thermal sensitivity of approximately 25 mK.

This high thermal sensitivity helps the detector distinguish relatively small differences in temperature, providing greater thermal separation between objects and their surroundings.

This is especially useful when observing environments with limited temperature contrast.

25mm F1.0 Objective Lens

The thermal imaging system uses a 25mm objective lens with an F1.0 aperture.

The lens configuration provides a balance between viewing area and longer-distance thermal observation, making it suitable for scanning open spaces, properties, farms and outdoor environments.

11.0° × 8.2° Field of View

The GOYOJO TE Series provides a listed field of view of approximately:

Horizontal: 11.0°
Vertical: 8.2°

This provides a practical viewing area for locating and observing thermal signatures across outdoor environments.

Up to 1,300m Thermal Detection

The TE Series provides a listed thermal detection distance of up to approximately 1,300 metres or 1,400 yards.

This specification represents thermal detection distance—the ability to detect the presence of a heat source at long distance. Detection should not be confused with recognition or positive identification distance.

800 × 600 AMOLED Display

Thermal imagery is presented through a 0.32-inch AMOLED display with 800 × 600 resolution.

AMOLED display technology provides strong contrast and deep black levels, helping temperature differences and thermal subjects remain clearly visible within the displayed image.

The 800×600 display resolution is separate from the native 400×300 thermal sensor resolution.

Up to 6 Hours Battery Runtime

The integrated rechargeable battery provides a listed operating duration of up to approximately six hours, giving the TE Series extended portable operation for outdoor observation.

20W Quick Charging

The GOYOJO TE Series supports up to 20W quick charging, reducing the time required to replenish the internal battery between observation sessions.

IP67 Environmental Protection

The device carries a listed IP67 protection rating, providing a dust-tight enclosure and resistance to temporary water immersion under defined conditions.

This protection makes the TE Series suitable for outdoor environments where exposure to dust, moisture and changing weather conditions can occur.

IP67 does not mean the device is designed for continuous underwater operation.

Suitable Applications

The GOYOJO TE Series is designed for:

• Wildlife observation
• Farm monitoring
• Property inspection
• Outdoor night-time observation
• Camping and exploration
• Search-support activities
• Electrical inspection
• Machinery monitoring
• Building heat-loss observation
• General heat-source detection

Safety & Care

Avoid pointing the thermal detector directly at the sun, welding arcs, lasers or other intense energy sources, as these can damage the thermal sensor.

Use compatible charging equipment and keep protective port covers properly closed during outdoor operation.
