FL4.4mm F1.0 LWIR Wide-angle Ge Lens For 800x600-17um

Infrared Fish Lens Description:

Focal Length 4.4mm F1.0 Infrared Wide-angle Lens For 640x480-17um Detector

8-14um Long Wave Infrared Fish Lens For Monitor Camera and Thermal Imaging Monitoring and Observation Equipment.

Uncooled Focal Plane Arrays (FPA) with a wavelength of 8-14μm now offer pixel pitches of 12 microns or less. To achieve high-resolution FPAs with VGA, XGA, and SXGA (1280x1024) resolutions, new lens designs are necessary to provide the required fields of view. The challenge for Infrared Optical Designers is to create lenses that can work with the same pixel pitch as the wavelength of the light being imaged. The lens specifications will need to consider the resolution required by the system.

With years of experience, our team of Rising infrared optics designers can meet the latest requirements for various security and surveillance LWIR applications. We offer long-range lenses that support the most advanced LWIR detectors, including up to 300mm continuous zoom LWIR lenses (up to 400mm LWIR recommended reflective types), and other infrared lenses that are perfectly suited for the 12μm SXGA (1280X1024) format.

This lens can produce the clearest image when used with 12μm SXGA (1280X1024)/HD LWIR detectors.

What causes unclear autofocus in infrared optics lenses?

There are multiple factors that can contribute to unclear autofocus in customized infrared optics lenses. To troubleshoot the issue, consider the following possibilities:

1. A large moving target in the lens screen during focusing (taking up more than 1/3 of the picture) can be readjusted for clearer focus.

2. Prolonged use of the lens can cause wear and tear on transmission parts like gears and CAM, resulting in unclear focus. Adjusting module or control board parameters can help restore clarity.

3. Hardware malfunctions, such as a faulty potentiometer, may require replacement of the affected hardware.

What leads to the failure of the lens control board or module to link up with the computer? 

There are several causes, but here are the top ones that you can resolve:

1. Attempt switching the USB port since it may not match the data cable.

2. Swap the data cable as it may not function with your computer or was wrongly chosen.

3. Inspect the wiring of the module or control board, as it may be unsteady.

4. If none of the above work, the problem could be with the hardware, so replace it.
