Description
ZnS Infrared Lenses | Custom IR Optical Lenses for Infrared Systems
ZnS infrared lenses are core optical elements made of high-purity zinc sulfide material. They feature excellent transmittance in mid and far infrared bands, moderate hardness and outstanding processability. Our product line covers multiple conventional lens types, and we support customized curvature, aperture and edge treatment. Matched with professional infrared anti-reflection coating, the lenses deliver stable optical performance. They are widely used in thermal imaging cameras, industrial temperature detection, defense EO/IR systems and infrared spectral instruments.
Core Advantages
- Wide transmission range from 3 μm to 14 μm, fits mainstream infrared working bands
- Good mechanical strength and scratch resistance, adapt to harsh field environments
- Easy for precision machining, achieve tight dimensional and surface tolerance
- Low optical absorption, stable imaging effect under long-term operation
- Support single/double side IR anti-reflection coating to enhance transmittance
- Complete specifications, fast delivery for standard models
Available Lens Types
- Plano-Convex ZnS Lenses: Widely used for light collimation and focusing
- Double-Convex ZnS Lenses: Ideal for high-efficiency beam focusing
- Meniscus ZnS Lenses: Applied for image correction and optical assembly
- Custom Shaped Lenses: Special curvature, aperture and irregular lenses per drawings
