Germanium Lens For Infrared Imaging Systems

I. Product Overview

This series of germanium lenses utilizes high-purity germanium (Ge) material as optical components, specifically designed for infrared imaging systems. Featuring excellent light transmittance (>83%~90%) in the 8-12μm wavelength band, they are compatible with infrared sensors of specifications including 640×512 and 384×288. The product line encompasses both fixed-focus and zoom models, meeting diverse application requirements in security surveillance, industrial inspection, thermal imaging equipment, and more.

II. Core Product Advantages

Outstanding optical performance with large aperture design (F/#=1.0~1.2), enhancing image clarity in low-light environments and compatibility with high-sensitivity sensors. Broad-spectrum transmittance >83% (>90% for specific models), effectively capturing infrared thermal radiation signals.

Wide field of view (FOV) range from 5.84°×4.69° (telephoto) to 93.7°×80.96° (wide-angle), covering both long-distance close-up and large-area monitoring requirements.

Strong environmental adaptability with broad operating temperature range: Most models support -40℃~+60℃, while specific variants can withstand -20℃~+80℃, suitable for extreme climates.

IP67-rated sealing provides dustproof and waterproof capabilities, ideal for outdoor or humid environments.

Optimized mechanical design: Athermalized focusing mechanism minimizes focal shift caused by temperature variations, ensuring imaging stability. Lightweight construction with minimum weight <10g (e.g., 9mm fixed-focus lens), facilitating integration into compact devices.
