Problems solved by technology
At present, most of the existing prisms are solid glass prisms, and there are very few liquid prisms with variable angles. The solid glass prisms have a significant disadvantage, that is, the angle of the prism cannot be changed, so it cannot meet the requirements of some optical instruments. changing requirements

The invention provides a liquid prism with a variable vertex angle, which is composed of a fixed framework (1), a movable framework (9), transparent glass (2), a double-torsion spring (3), an elastic sealing rubber skin (4), a rubber bottom skin (6), a rubber corrugated soft skin (5), a circular-arc-shaped iron angle scale (7), a movable magnetic baffling column (8), a baffle indicator (10) and a base (12), wherein a movable rubber skin cover (11) can be arranged on the upper surface so as to conveniently fill and pour liquid. A rotary movable framework (9) utilizes the circular-arc-shaped iron angle scale (7), the movable magnetic baffling column (8) and the baffle indicator (10) to fix the angle of the vertex angle; when the liquid is filled, the liquid prism is formed; the circular center of the circular-arc-shaped iron angle scale (7) is located at the vertex angle of the prism; and the baffle indicator (10) and the glass are the same in thickness and are located on the same straight line. The liquid prism with the variable vertex angle can meet the requirements that some optical systems are variable to the angle of the prism and has the advantages of variable vertex angle and variable prism reflection rate; and the liquid prism with the variable vertex angle has the advantages of simple structure, low cost, easiness for cleaning and easiness for installation.
Description
technical field [0001] The invention relates to a novel variable apex angle liquid prism structure and its working principle, and belongs to the technical field of applied optical devices. Background technique [0002] Liquid optics is now a popular subject, characterized by flexible and adjustable optical properties, and constitutes a tunable optical system. Liquid prism is a kind of prism mainly composed of liquid, which can be used alone or integrated in the optical system for various new optoelectronic devices. By changing the angle of the prism and changing the type of liquid, the optical properties of the liquid prism can be flexibly changed. It can be applied to: optical communication devices, dye lasers, liquid analysis in the field of biomedicine, optical imaging systems, measurement systems such as tilt measurement, and teaching experiments. [0003] The variable angle liquid prism is a liquid prism with a variable top angle. The top angle of the liquid prism is d...
