Schlieren System

About Schlieren System

Overview

A high-precision optical flow visualization system designed to make shock waves, expansion waves, and density gradients visible in compressible flow studies. Based on the classic Toepler Schlieren method, the system enables accurate qualitative and quantitative analysis of supersonic and transonic flow phenomena that are otherwise invisible to the naked eye.

Key Features

• High-Sensitivity Visualization: Reveals shock waves and flow gradients clearly
• Non-Intrusive Measurement: Optical method with zero flow disturbance
• Precision Alignment System: Fine adjustments for accurate optical setup
• Modular Design: Suitable for wind tunnels, nozzles, and lab setups
• Custom-Built Configurations Available
