ISP Optics Zinc Selenide (ZnSe) Meniscus Lenses feature positive and negative meniscus designs that minimize spherical aberration. Positive meniscus lenses enable smaller spot sizes than possible with PCX lenses, making them ideal for use in CO2 laser applications for precise marking or cutting. Negative meniscus lenses are used to increase the focal length when used with additional lenses, decreasing the numerical aperture of an optical system. ISP Optics Zinc Selenide (ZnSe) Meniscus Lenses are available in standard imperial sizes either uncoated or Broadband Anti-Reflection (BBAR) coated for enhanced transmission from 8 – 12µm.
This comparison of the performance of aspheric, achromatic, and spherical PCX lenses in different situations reveals the ideal use cases for each type of lens.
