Embodiment Construction

[0015] As shown in FIG. 1 a and FIG. 1 b , the optical system of the present invention includes a first optical device 1 , a second optical device 2 , a thrust device 3 , and a housing 5 . The first optical device 1 and the thrust device 3 are relatively fixedly arranged on the housing 5 , and the second optical device 2 is arranged between the first optical device 1 and the thrust device 3 . The first optical device 1 includes a lens 12 . One side of the lens 12 is provided with a lens holder 13 , and the lens holder 13 includes a support body 11 . The support body 11 is a protrusion extending toward the center of the lens 12 . The second optical device 2 is a polarizing beam splitter 21 . The thrust device 3 then includes a spring 32 .

[0016] As shown in FIG. 2a, in this embodiment, the leaning body 11 is four flange claws. However, the body 11 can be easily transformed into other implementation states except for the implementation state of using the above-mentioned cl...

Abstract

The optical system includes one first optical unit, one second optical unit and one push unit. The first optical unit has one back body on its one side, and the second optical unit is set between the first optical unit and the push unit. In the optical system, the second optical unit is pushed by the push unit towards the back body to maintain the fixation of the first optical unit relatively to the second optical unit.

Description

technical field [0001] The invention relates to an optical system and a positioning method of the optical system, in particular to an optical system and a positioning method of the optical system which can reduce the influence of the accuracy of internal components. Background technique [0002] In recent years, a projector has become a device capable of efficiently providing information. Whether for presentation or entertainment, users can widely use projectors to present information. [0003] The projector combines the polarized light splitting characteristic of a polarized beam splitter to allow users to project images they want to present on a screen. Generally speaking, a projector includes a light engine and a lens. The optomechanical system includes a light source, a polarized beam splitter and at least one panel. In a projector, the image is produced through the cooperation of the optical-mechanical system and the lens. The function of the ...
