Product Overview
ZnSe Plano-Convex Lens with 25.4mm Diameter and 500mm Focal Length
The iroptical 25.4mm ZnSe plano-convex lens is precision-engineered for high-power CO2 laser focusing and long-wavelength infrared (LWIR) thermal imaging applications. Manufactured from premium zinc selenide substrate, this optical component features low bulk absorption and exceptional wavefront performance across the 7 to 12 micron spectral range. With a 500mm focal length, it serves as an ideal solution for minimal spot size focusing and precise beam collimation.

Industrial Applications
Our high-precision zinc selenide lenses are designed to meet the rigorous performance standards of advanced industrial and scientific systems, including:
Laser Processing: Functions as a premium CO2 laser lens for precision laser engraving, cutting, and marking systems operating at 10.6 microns.
Thermal Imaging & LWIR Metrology: Deployed in long-wave infrared cameras and spectroscopic instruments to collect and focus thermal radiation with maximum transmission.
Beam Collimation: Utilized within complex infrared optics assemblies to expand, parallel, or guide infrared laser beams while eliminating aberrations.
Custom Optics and World-Class Precision
Beyond our standard catalog components, iroptical provides extensive manufacturing capabilities for customized optical designs. We offer flexible tailoring of diameters, focal lengths, centration tolerances, and custom anti-reflective coatings to fit your proprietary system configurations. Every custom znse lens undergoes strict metrology control to ensure it complies with your exact technical drawings and international quality standards.
Overcome Lead Time Delays: Secure Your Order
For R&D engineers and purchasing managers, unexpected supply chain bottlenecks and long lead times for custom optics can severely disrupt project timelines. Additionally, low-grade coatings often lead to premature thermal degradation under high laser power. To mitigate these risks, iroptical maintains an extensive in-stock selection of standard ZnSe components for rapid delivery. Whether you require immediate prototyping or high-volume custom production with guaranteed quality, our team delivers reliable lead times.
