Square Quartz Capillary for Optical Path & Sensor Applications

Our JGS2 fused quartz square capillary tube is engineered for optical path alignment, sensor module integration, and sampling channel applications requiring excellent visible-light transmission and dimensional stability.
The 3×3 mm outer dimension and 2×2 mm inner channel enables a controlled optical cavity, fluid sampling space, or precision alignment interface for laser coupling and optical sensing assemblies.
