Detail Information
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

四、专属 FAQ
Q1: What are ZnS infrared lenses used for?
A: ZnS infrared lenses are mainly used to focus and collimate infrared light. They are essential parts for thermal imaging, temperature detection, defense optoelectronic equipment and spectral analysis instruments.
Q2: What types of ZnS lenses do you supply?
A: We provide plano-convex, double-convex, meniscus lenses and other standard types. We also produce non-standard custom lenses based on your design drawings.
Q3: Can you add anti-reflection coating on ZnS lenses?
A: Yes. We offer single-side and double-side infrared AR coatings, which can effectively reduce light reflection and improve overall optical efficiency.
Q4: How about the durability of ZnS lenses?
A: ZnS has proper hardness and mechanical stability. It works reliably in normal indoor and outdoor environments, and is resistant to daily abrasion.
Q5: Can you make ZnS lenses with special focal length?
A: Absolutely. We can customize focal length, curvature and dimensions to match your optical system design.
