Schlieren Systems

Schlieren Systems include the determination of refractive index, wind tunnel research, fluid and air current flow, internal character of glass, flame analysis, sound velocity, and the mass of microscopic particles. Brightness variations on the screen will occur according to changes within the medium of the test area. A 35mm camera can be added to the system, enabling a photographic record to serve as a permanent reference. Schlieren Systems, in lower light intensities, may be better enhanced with a video camera and monitor combination. Using video, your results are enlarged, eye strain is reduced, and you can record your results by video printer or commercial video cassette recorder. 

Each system contains 2 aluminized first-surface spherical f/10 mirrors (4 ¼" or 6" diameter) with λ/8 surface accuracy, overcoated with silicon monoxide and mounted in metal stands. Also included: light source, assembled Foucault tester, information, and instructions.
