Compact thermal imaging for Handheld Observation

A thermal imaging monocular is designed to provide infrared observation in a compact handheld form. Unlike larger electro-optical platforms, a monocular focuses on portability and ease of operation.

The Ferolix FX Series is specifically designed as a lightweight handheld infrared monocular. Its configuration includes an uncooled microbolometer, multiple detector resolutions, optional laser ranging and integrated digital functions.

Sensor Resolution

FX2, FX3 and FX6 are associated with 256×192, 384×288 and 640×512 detector configurations respectively.

For distributors, these models provide a foundation for different product positioning.

A compact product portfolio can therefore include multiple thermal resolutions while maintaining a similar handheld product concept.

Lens Configuration

Lens selection is another important consideration.

The FX Series specifies lens options including 15mm, 19mm, 25mm and 35mm depending on configuration.

Different focal lengths provide different fields of view and image scales. Buyers should therefore specify the intended application before deciding on a lens.

Display and Image Modes

The FX Series uses a 0.39-inch 1024×768 color OLED monocular display.

It also supports multiple image patterns including Black Hot, White Hot, Rainbow, Iron and Medical.

Digital zoom is available at 1×, 2×, 3× and 4×.

These functions can be important when designing a consumer-facing or professional handheld product because they provide users with different ways to interpret thermal scenes.

Laser Ranging

An optional LRF function is available, with a stated maximum range of 1km for the relevant configuration. This can turn a basic thermal monocular into a combined observation and distance-measurement device.

For distributors, integrated ranging can create a clear product differentiation point.

Recording and WiFi

The FX Series supports snapshot and video recording as well as WiFi.

These functions make it possible to capture observations and transfer images or video through the supported wireless system.

For modern product development, recording and connectivity are increasingly relevant because users often expect digital data functions in addition to optical observation.

Environmental Design

The FX Series is specified with IP66 encapsulation, an operating temperature range of -20°C to +55°C and a weight of no more than 400g including battery.

The compact dimensions are specified at no more than 180mm × 75mm × 55mm.

These specifications are particularly relevant to distributors who need to define product positioning for outdoor markets.

Questions for OEM Buyers

Before sourcing a thermal monocular, a B2B buyer should define:

• Detector resolution

• Lens focal length

• NETD

• Display type

• Digital zoom

• LRF requirement

• WiFi requirement

• Recording

• Battery configuration

• IP rating

• Operating temperature

• Product weight

• Branding and packaging requirements

Conclusion

Thermal imaging monoculars are compact platforms that can combine infrared imaging with digital functions such as ranging, WiFi and recording.

The Ferolix FX Series provides multiple detector and lens configurations, giving distributors and OEM buyers several options when developing a thermal observation product line.
