Aspheric Lenses

Our top-grade custom IR Aspheric Lenses are engineered as upgraded alternatives to traditional spherical infrared lenses, a top pick for global manufacturers of thermal imagers, automotive night vision and LiDAR infrared devices. Crafted from high-purity Germanium, Silicon, ZnS and ZnSe infrared crystals, our IR aspheric optics cover full SWIR, MWIR, LWIR infrared spectrum to satisfy high-standard infrared optical projects across automotive, security, aerospace and precision industrial inspection sectors.

A single IR aspheric lens completely eliminates spherical aberration, replacing cumbersome multi-lens spherical combinations. It effectively miniaturizes your end products, reduces raw material costs and improves your finished equipment’s market competitiveness. We adopt ultra-precision single-point diamond turning process to achieve ultra-low surface roughness and tight dimensional tolerance, guaranteeing stable optical performance under extreme high/low temperature, vibration and humid outdoor working environments.

Customizable broadband IR AR coating, scratch-resistant DLC hard coating and spectrum-targeted anti-reflection films are available to maximize infrared transmittance and boost lens durability against scratch, moisture and oxidation. We support full customization based on your optical drawings for focal length, diameter and curvature, flexible small MOQ for prototype testing and stable mass-volume delivery for bulk orders.

Widely adopted in vehicle thermal night vision, industrial temperature measuring cameras, perimeter security infrared detectors and aerospace infrared sensing equipment, our high-performance IR aspheric lenses are trusted by worldwide optical designers and equipment manufacturers.
