Thermal Camera Lenses 4mm–45mm for Thermal Imaging Cameras
Overview
Upgrade your infrared imaging system with interchangeable thermal camera lenses designed for compatible thermal imaging cores. Available focal lengths from wide-angle to telephoto options help you select the appropriate field of view for drone imaging, industrial inspection, security surveillance, and long-range observation.
Key Features
• Multiple focal length options from 4mm to 45mm
• Designed for long-wave infrared (LWIR) thermal imaging
• Anti-reflective (AR) coating for infrared optical performance
• Precision-machined metal housing for stable optical alignment
• Interchangeable lens options for compatible thermal camera cores
• Wide-angle and longer-focal-length options for different imaging distances
• Custom mounting options may be available upon request
Available Focal Lengths
• 4mm: Wide-angle imaging for close-range monitoring and aerial mapping
• 6.8mm and 9mm: Suitable for general inspection and medium-range imaging
• 15mm and 25mm: Balanced field of view for industrial and security applications
• 35mm and 45mm: Narrower field of view for longer-range observation

Compatibility Notes
Before purchasing, confirm the lens mount interface, detector resolution, pixel pitch, optical back focal distance, and required field of view. Not every focal length is compatible with every thermal camera.
For radiometric cameras that measure temperature, replacing the lens may require recalibration to maintain measurement accuracy. Manual focusing may also be necessary, depending on the lens design.
FAQ
Q1: How do I choose the right focal length?
A: Shorter focal lengths provide a wider field of view for close-range and wide-area imaging. Longer focal lengths are generally better suited to narrower views and distant targets.
Q2: Are these lenses compatible with all thermal cameras?
A: No. Compatibility depends on the mounting interface, detector resolution, pixel pitch, optical design, and back focal distance. Please confirm these details before ordering.
Q3: Can I replace my existing thermal camera lens?
A: Replacement is possible when the new lens matches your camera's optical and mechanical requirements. Refocusing may be needed after installation.
Q4: Will changing the lens affect temperature measurement?
A: It may. Radiometric thermal cameras may require recalibration after a lens replacement to maintain accurate temperature readings.
Q5: Can I request a custom lens configuration?
A: Custom focal lengths or mounting options may be available. Contact us with your camera model and application requirements to confirm feasibility.
