Uncoated CVD ZnSe Plano-Convex Lens (D: 12.7mm, EFL: 20mm, 10.6μm)

This precision plano-convex lens is manufactured from high-purity Chemical Vapor Deposition Zinc Selenide (CVD ZnSe), optimized specifically for 10.6 μm thermal imaging and CO2 laser systems. Featuring a focal length of 20.00 mm and a compact 12.70 mm outer diameter, this uncoated element offers ultra-low bulk absorption, high mechanical stability, and exceptional transmission in the long-wave infrared (LWIR) spectrum. As a versatile component in ZnSe optics, it serves as an ideal solution for primary beam focusing and optical collimation.

Technical Specifications

Primary Applications

Due to its precise optical figure and physical durability, this component is routinely integrated into high-demand mid-wave and long-wave infrared equipment, including:

• CO2 Laser Processing Systems: Ideal focusing optics for small-footprint CO2 laser engravers, markers, and precision cutting machines utilizing CO2 laser lenses.

• Thermal Imaging & Detectors: Signal gathering and light collimation in LWIR sensing arrays and radiometric inspection devices.

• Optical Prototyping & R&D: Uncoated substrates allow custom post-coating or immediate integration into experimental test benches.

Customization & Engineering Support

While iroptical maintains an extensive in-stock selection of standard components for rapid deployment, we specialize in high-level manufacturing flexibility. Our optics facility supports OEM modifications, including specialized anti-reflective (AR) coatings (such as 8-12 μm broad-band AR or dual-band coatings), custom edge dimensions, alternative radii, and tight-tolerance housings. Every production batch undergoes rigorous interferometric and spectrophotometric quality assurance to guarantee consistent performance.

Technical Inquiries & Ordering

Balancing stringent optical tolerances, predictable lead times, and custom prototype requirements can be challenging. Whether you require immediate off-the-shelf dispatch or modified custom infrared optics tailored to your optical design software specifications, our engineering team is ready to assist.
