Abstract
Optics are stabilized by suspending an optical element in a semi-liquid, either freely or by supports allowing for substantial freedom of movement. The semi-liquid provides support for the optical element, damping of oscillation and minimal distortions resulting from inhomogeneous adsorption of heat by the fluid media.
Claims17
A stabilized optical apparatus comprising:
- a housing substantially filled with a transparent semi-liquid and having at least one transparent window;
- and an optical structure immersed in said semi-liquid, wherein said semi-liquid is a colloidal solution thickened by a high molecular weight thickener.
A stabilized optical apparatus comprising:
- a cylindrical casing substantially filled with an aqueous transparent semi-liquid and having at least one transparent window, said casing having an axis normal to said window;
- an optical structure comprising at least one optical element in light receiving relationship to said window, having a center point on said axis and means for imparting neutral buoyancy to said optical element, wherein said semi-liquid is a colloidal solution having a high molecular weight thickener.
