Zinc Selenide Aspheric Lenses — GLH7AL Series
CVD laser-grade ZnSe aspheric lenses; select GLH7AL1 for the 4 μm design wavelength or GLH7AL2 for 10.6 μm.
Use the GLH7AL1 and GLH7AL2 branches to reach the corresponding aspheric-lens models. After choosing the design wavelength, compare focal length, diameter and thickness; retain the specified surface orientation when matching an existing optical layout.
Choosing Zinc Selenide Aspheric Lenses — GLH7AL Series
- Choose the 4 μm or 10.6 μm design branch required by the application.
- Check the listed aperture and focal geometry against beam size and the required working space.
- Provide the original drawing or prescription for a replacement, and state laser power and pulse conditions if they require confirmation.
Use the optical-parameter guide to distinguish focal, aperture and surface specifications.
