ZnSe CO2 Laser Focus Lenses For Laser Cutting Machine Meniscus Lenses
Zinc Selenide (ZnSe) Meniscus Lenses are designed for focusing or collimation applications in the mid-wave and longwave infrared spectrum. Manufactured by II-VI, these lenses feature Infrared ZnSe material with <0.0005cm-1 bulk absorption at 10.6µm and are available uncoated or with a variety of broadband anti-reflection coating options. The 8-12µm coating is ideal for use with CO2 lasers and thermal camera applications, whereas the dual band 3-12µm coating is ideal for hyperspectral applications. Zinc Selenide Meniscus Lenses feature an irregularity of <λ/20 at 10.6µm, 40-20 surface quality, and <50Å surface roughness. Three diameter options are available, with effective focal lengths ranging from 12.7mm to 250mm.
