High Precision Mirrors for Schlieren Imaging
23/05/2017 Optical Surfaces Ltd
Optical Surfaces Ltd. is a leading producer of high precision mirrors for Schlieren imaging applications involving airflow turbulence, explosive shockwaves, gas leaks and visualisation of transparent thermal phenomena.Drawing upon its uniquely stable manufacturing environment - Optical Surfaces is able to routinely produce the highest quality concave spherical mirrors (up to 800mm in diameter) for Schlieren imaging systems in a range of materials including Pyrex, Zerodur and ULE.
Optical Surfaces' optical craftsmen routinely produce spherical mirrors with surface accuracy of better than lambda/10 with particular emphasis on smoothness of the profile. Final characterisation of surface smoothness using highly accurate interferometric measurements. Ultra high precision surface finish and durable optical coatings combine to provide superior Schlieren image quality.
Schlieren imaging is a widely-accepted method for visualising density variations in transparent media. In one of the most common types of Schlieren imaging system a source directs light onto a spherical mirror, which collimates the light and redirects it onto a second identical mirror. The resultant image may be captured by an imaging camera or on a screen.
