What detector pixel pitches and formats do your LWIR lenses support?
Our standard and custom infrared optics support LWIR, MWIR, and SWIR systems, with designs tailored to cooled and uncooled detectors. Chalcogenide LWIR lens options accommodate 8, 12, and 17 µm pixel pitches and detector resolutions including 384 × 288, 640 × 512, and 1280 × 1024. Multiple focal lengths and athermal design options help match detector dimensions, spectral response, and imaging requirements.
How does passive athermalization maintain image focus across extreme operating temperatures?
Passive athermalization balances the temperature-dependent optical properties of lens materials with the thermal expansion of mechanical components. By carefully selecting materials and optimizing lens geometry and spacing, the design compensates for focus shifts without motors, heaters, or active adjustment. This helps maintain image sharpness across the specified operating temperature range, with performance verified through thermal and optical testing.
What is the advantage of chalcogenide glass lenses?
Chalcogenide glass is well suited to high-volume precision molding, reducing per-lens processing time while improving production efficiency and consistency. Aspheric designs can also reduce lens element counts and assembly steps, helping lower overall manufacturing costs at scale.
What is your typical turnaround time for standard chalcogenide lens prototyping?
For custom optical designs (modified EFL, FOV, or mechanical interfaces), our typical prototyping cycle ranges from 7 to 8 weeks from optical drawing approval to prototype delivery. For standard Off-The-Shelf (OTS) lens options, we maintain buffer stock for rapid sampling within a few business days.
Are your infrared lenses compliant with international environmental standards?
What information do I need to provide to get a custom lens recommendation?
For an accurate optical assessment, please share your detector resolution and pixel pitch, operating wavelength range, required field of view (FOV) or effective focal length (EFL), and target f-number. Include any mounting requirements, size constraints, and operating conditions, such as temperature range, shock, and vibration.
