Product Details

ZnSe/Sapphire IR Optical Glass Stepped Windows

Custom step heights, widths and geometries can be engineered to deliver targeted optical performance including beam shaping and spectral filtering.

The stepped profile also enhances the mechanical strength and structural stability of the window substrate. Widely adopted in laser technology as components inside laser resonators, these windows help optimize laser beam quality and beam characteristics.

Basic Structure:

1. Step profiles are precision-machined onto the surface or edge of the optical substrate to create regions of varying thickness.

2. Designs may feature single or multiple step levels, with step height differences ranging from a few microns to several millimeters.

Common forms:

1. Central step: the central region of the window is raised or recessed.

2. Edge step: one side or the peripheral edge of the window is thinned.

Functions:

1. The step profile generates a defined optical path difference (OPD) for phase modulation and interferometry applications.

2. Zones with different thickness can be paired with diaphragms to mask the incident beam.

3. The machined stepped geometry simplifies window mounting and interfacing with other optical assemblies.
