Optical path sleeve for atomic absorption spectrometers and UV spectrophotometers, reducing stray light and improving signal-to-noise ratio in precision measurements.
Laser cavity protection tube and gas laser discharge outer tube, providing optical-grade transmission while protecting internal laser components.
Vacuum chamber light-transmitting sleeve and process gas observation tube for semiconductor fabrication and inspection systems.
Micro-volume liquid flow observation tube with minimal residue retention for biochemical analysis and microfluidic applications.
Unlike standard externally polished tubing where the inner wall can trap liquid and scatter light, this double-side polished quartz tube delivers consistent optical transmission, minimal liquid residue and low optical distortion—making it the preferred choice for high-precision optical and spectroscopic applications.
