22.5–105 mm LWIR Camera Module: Buyer’s Guide to Specifications and OEM Integration

A 22.5–105 mm LWIR camera module is a long-wave infrared imaging assembly intended for applications that need thermal imaging at different viewing distances or fields of view. Before requesting a quotation, confirm whether the range describes interchangeable fixed-focus lens options or a continuous zoom lens; these designs have different integration and control requirements. Then match the optics, detector, image output, mechanical envelope, and environmental needs to your system. This guide provides a practical framework for evaluating specifications and discussing OEM integration with a supplier such as Hope-Wish.

Key Takeaways

• Clarify what “22.5–105 mm” means for the offered configuration, including whether the lens is fixed, interchangeable, or continuously zooming.
• Evaluate the complete imaging chain: focal length, detector resolution, pixel pitch, thermal sensitivity, frame rate, image processing, and interfaces.
• Share your application, installation constraints, and acceptance criteria with suppliers before comparing prices or lead times.
• Request configuration-specific documentation and confirm OEM responsibilities, sample evaluation, and production terms in writing.

Who This Guide Is For

This guide is for OEM engineers, system integrators, security product buyers, and project teams sourcing thermal imaging equipment. It is particularly relevant when a design calls for a longer-range viewing option or needs to fit an LWIR module into an existing camera, enclosure, or monitoring platform. Buyers at the early specification stage can use it to prepare an RFQ, while teams comparing suppliers can use it as a checklist. The right choice depends on the use case and configuration rather than focal length alone.

Understanding a 22.5–105 mm LWIR Module

What the focal length range tells you

LWIR refers to long-wave infrared imaging; many thermal camera systems are designed to detect radiation in an approximately 8–14 µm wavelength band, although the exact spectral response depends on the detector and optical design. A lens’s focal length affects its field of view: a longer focal length generally produces a narrower view of the scene, which can help when the target is distant or occupies a small portion of the image. It does not, by itself, establish detection range or guarantee that a target can be identified. Those outcomes also depend on the detector, target size and temperature contrast, atmospheric conditions, and image processing.

The notation “22.5–105 mm” should be confirmed with the supplier rather than assumed to describe a continuous zoom. It may refer to a zoom range, a choice of fixed focal lengths, or a project-specific optical configuration. Ask for the available focal-length options, corresponding fields of view, focus method, and any zoom-control requirements. A field-of-view table for the exact detector and lens combination is more useful than a focal-length number in isolation.

Specifications to Compare

Optics, detector, and image performance

Start with the detector resolution and pixel pitch, then assess them alongside the lens and the target size at the intended distance. Resolution is stated in pixels, while pixel pitch is commonly stated in micrometres (µm); neither figure alone describes the full system’s practical performance. Request the field of view for each proposed lens configuration and confirm whether focus is manual, motorized, or fixed. If your application requires temperature measurement, ask separately about measurement functions, calibration conditions, and stated accuracy rather than assuming that every thermal imaging module is a radiometric camera.

Thermal sensitivity, often specified as NETD in millikelvins (mK), can help compare a module’s ability to distinguish small temperature differences under defined test conditions. Ask the supplier for the measurement conditions and the value applicable to the quoted configuration. Also confirm frame rate in hertz (Hz), image formats, and available processing functions, since these affect how the output fits your system. Treat performance figures as comparable only when the methods and operating conditions are sufficiently clear.

Electrical, mechanical, and environmental fit

Check the module’s power input, consumption, startup behavior, connector pinout, and available control signals against your host platform. Request a mechanical drawing that identifies the mounting points, dimensions, optical axis, and required clearance around the lens. Confirm operating and storage temperature limits, vibration or shock requirements, and any enclosure or ingress-protection expectations for your finished product. These limits should come from the configuration’s documentation; do not infer them from the module’s intended application.

For integration, identify the video or data interface, command protocol, software development resources, and any host-side processing requirements. Clarify whether the module supports the image output format and control workflow your system uses. If your product requires a particular supply voltage or operating temperature, put the exact values and tolerances in the RFQ; for example, a project might specify a 12 V input or an operating range from −20 °C to +60 °C, but these are buyer requirements to verify, not assumed module specifications. Early agreement on these details can prevent redesign after sample evaluation.

Match the Configuration to the Application

For perimeter monitoring or long-distance observation, a narrower field of view may help place more pixels across a distant target, but it also reduces scene coverage. For situational awareness, a wider view can capture more context, although small targets may occupy fewer pixels. A multi-position installation may benefit from a choice of focal lengths, while a system that needs to change framing during operation may require a genuine zoom design and compatible control functions. Ask the supplier to assess the target dimensions, viewing distance, scene width, and required image detail together.

Include operational conditions in this assessment. Fog, rain, dust, background temperature, and obstructions can affect what a thermal camera can observe, and a longer focal length does not remove those constraints. If the module will be installed behind a protective window, confirm that the window material and optical design are suitable for the intended LWIR band. Test the assembled system in representative conditions where practical, rather than relying only on a standalone module demonstration.

A Practical Selection Framework

1. Define the task. Describe what the system must observe, the target’s approximate size, the viewing distance, and whether the goal is detection, recognition, or temperature measurement.
2. Set optical requirements. Specify scene coverage and target detail, then request field-of-view information for each proposed 22.5–105 mm configuration.
3. Confirm detector and output needs. State required resolution, frame rate, image format, processing, and any radiometric functions.
4. Document integration constraints. Provide the available space, mounting method, input power, interface, environmental range, and host-system details.
5. Agree on evaluation criteria. Define what sample testing must demonstrate, which documents are required, and how configuration changes will be handled before production.

Pricing, MOQ, and Lead Time

Pricing for an LWIR module depends on the confirmed optical and detector configuration, requested interfaces, customization, and order quantity. A quote should identify the exact configuration and distinguish standard items from engineering or OEM work. Minimum order quantity (MOQ) and lead time can vary by configuration, component availability, and project requirements, so request current terms directly rather than relying on general estimates. For a fair comparison, ask each supplier to quote the same specification and state whether sample costs, tooling, and integration support are included.

Supplier Evaluation Checklist

• Can the supplier explain whether 22.5–105 mm is a zoom range or a set of lens options?
• Will the quotation include a configuration-specific datasheet, mechanical drawing, interface details, and field-of-view information?
• Can the supplier clarify detector, sensitivity, frame-rate, power, and environmental specifications for the exact offered module?
• Are sample evaluation, customization scope, MOQ, lead time, warranty terms, and production change control clearly described?
• Can the supplier identify what your team must provide for integration, such as host requirements, connectors, software needs, or test criteria?

Be cautious when a supplier provides headline figures without explaining their configuration or measurement conditions. Also avoid comparing price before confirming that the competing offers use equivalent optics, detector performance, interfaces, and support scope. Written answers reduce uncertainty for engineering, procurement, and production teams. If any requirement is not yet fixed, mark it as open in the RFQ and ask the supplier to identify the available options and trade-offs.
