Abstract

The invention relates to the technical field of optical prisms, in particular to an adjustable optical prism. The adjustable optical prism comprises three groups of lenses which are arranged in a triangular shape; a first fixing sleeve, a second fixing sleeve and a third fixing sleeve respectively sleeve the outer surfaces of the three groups of lenses; a first connecting pile is fixed at one end,deviating from the third fixing sleeve, of the lens; a second connecting pile is fixed to the end, deviating from the third fixing sleeve, of the first fixing sleeve; the first connecting pile is rotationally connected with the second connecting pile through a hinge shaft; and an adjusting assembly is fixed to the end, away from the third fixing sleeve, of the first fixing sleeve and comprises afixing frame, the inner wall of the fixing frame is rotationally connected with the first connecting pile and the second connecting pile through rotating shafts, and a first connecting rod is rotationally connected to the end, away from the adjusting assembly, of the first fixing sleeve through a hinge shaft. The angle formed by the three lenses can be conveniently adjusted, and the adjusting stability is improved.

Description

technical field [0001] The invention relates to the technical field of optical prisms, in particular to an adjustable optical prism. Background technique [0002] Prisms are widely used in optical instruments. Prisms can be divided into several types according to their properties and uses. For example, "dispersive prisms" that decompose composite light into spectra in spectroscopic instruments, and equilateral triangular prisms are more commonly used. [0003] The angles of the three lenses of the prism are different, and the angle of the refracted light will also change, which can play different roles in optical instruments. However, the angles of the three sides of the existing prism are fixed, and the angles of the three sides cannot be adjusted conveniently. , can only replace the whole prism to adapt to the use of different functions, and the operation is troublesome, so it is urgent to design an adjustable optical prism to solve the above problems.
