SO-W04 SERIES
SO-W04 laser-grade K9 plane windows are designed for protective interfaces in collimated laser paths where surface quality, flatness and low reflection are more critical than in general-purpose covers.
Product Overview

Engineering Guidance
Choose the window around transmitted wavefront and environment
Performance considerations
The available coating bands allow the window to be matched to visible, near-infrared and short-wave infrared sources. The parallel plate format keeps optical power near zero, while precision polishing helps limit beam distortion and scatter.
Selection and mounting
Confirm operating wavelength, incidence angle, fluence, pulse duration and beam diameter before selection. A coating band match does not by itself establish laser-damage suitability.
Need a different diameter, tolerance or coating?
Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
