INDUSTRY COMPONENT

Optical Windows

Transparent optical interface in flow cells for light transmission in spectroscopy and analysis systems.

Component Specifications

Definition
Optical windows are precision-engineered transparent components integrated into flow cells to allow controlled light transmission for spectroscopic measurements, chemical analysis, and process monitoring while maintaining fluid containment and optical clarity.
Working Principle
Optical windows function by transmitting specific wavelengths of light through the flow cell's fluid path, enabling real-time spectroscopic analysis (UV-Vis, fluorescence, IR) without direct contact between optical sensors and the sample fluid, maintaining measurement accuracy and preventing contamination.
Materials
Fused silica (UV-Vis applications), optical glass (visible spectrum), sapphire (high durability), quartz (UV transmission), borosilicate glass (chemical resistance), with anti-reflective coatings and surface treatments for enhanced performance.
