Product Description

Overview

ZnSe half-ball lenses provide compact infrared coupling in assemblies where a shorter profile is required than a full ball lens. The hemispherical geometry can help reduce package height while supporting fiber coupling, detector coupling, and compact IR optical paths.

Where Half-Ball Lenses Fit

Half-ball lenses are useful for small optical modules that need efficient coupling and simple mechanical integration. Typical use cases include infrared fiber coupling, laser-to-detector coupling, compact sensing systems, and miniature optical packages.

Engineering Notes

Before release, confirm lens diameter, package height, mounting datum, working distance, and coating target. These inputs help determine whether a half-ball lens is the right compact coupling format for the assembly.
