Abstract
An optical system is provided that has an enclosure which is substantially filled with a fluid. The enclosure also has an aperture for receiving an electromagnetic wave that is altered by an optical component contained in the enclosure. The enclosure also has an aperture mask and blocker that are at least partially immersed in the fluid.
Claims20
An optical system, comprising:
- an enclosure substantially filled with a fluid and having an aperture for receiving an incident electromagnetic wave;
- an optical component contained within the enclosure for altering the electromagnetic wave received by the enclosure;
- and
- a wave blocking member at least partially immersed in the fluid for minimizing the scattering of the incident electromagnetic wave.
An optical system, comprising:
- an enclosure substantially filled with a fluid and having an aperture for receiving an incident electromagnetic wave;
- an optical component contained within the enclosure for altering the electromagnetic wave received by the enclosure;
- and
- a rail at least partially immersed in the fluid for reducing turbulent flow in the fluid.
An aperture mask for use in an optical system that is at least partially embedded in a fluid, comprising:
- a frame providing a mounting surface for an optical component, the frame further defining an aperture for the optical component;
- a wave blocking member connected to the frame for minimizing the scattering of incoming radiation;
- and
- a rail connected to the frame that defines a channel for reducing turbulent flow in the fluid.
A beamsplitter assembly for use in a projector system, comprising:
- a housing filled with a fluid and having an aperture for receiving an incident electromagnetic wave;
- a polarizing plate that alters the incident electromagnetic wave;
- a frame defining a mounting surface for the polarizing plate, the frame connected to the housing at a predetermined angle with respect to the incident electromagnetic wave;
- a flanged lip associated with the frame and extending along an end of the frame which is distal from the incident electromagnetic wave for impeding scattering of the incident electromagnetic wave;
- and
- at least one rail affixed to the frame and extending downwardly to form a channel along an underside of the frame for reducing turbulent flow in the fluid.
