Description
Technical field
The present invention relates to a kind of optical element fixed adjuster and optical devices, particularly a kind of can be in order to fixing and adjust the optical element fixed adjuster of SCR colour wheel and light harvesting post and have fixing and adjust the optical devices of SCR colour wheel and light harvesting post.
Background technology
Existing colour wheel (Color Wheel) and light harvesting post (Light Integration Rod) generally use different holding structures to fix in a digital light respectively and handle in (Digital LightProcessing) projector, so that the relative position of control colour wheel and light harvesting post.In optical projection system, light the position of each optical element of process concerning the performance of the whole image quality of digital light projection machine, so the status requirement of each optical element must be very accurate.Yet, because existing colour wheel and light harvesting post are separately fixed on the different holding structures, therefore except considering the relative position of colour wheel and light harvesting post, also must notice the relative position of colour wheel and light harvesting post and other optical element, thus, be bound to such an extent that the long time of cost is adjusted the position of each optical element in the digital light processing projector, and also will make each optical element of adjustment to the degree of difficulty of exact position increase relatively.
Because the problems referred to above, there is the dealer to develop to seize on both sides by the arms simultaneously the fixed adjuster of colour wheel and light harvesting post recently.But this kind fixed adjuster can only be done the simple adjustment of one dimension or two-dimensional directional mostly, that is it can't do multi-faceted adjustment fully.In addition, this kind fixed adjuster can't carry out Precision trimming mostly, therefore, can't obtain preferable adjustment effect.For general colour wheel, the precision adjustment of existing fixed adjuster still can maintain the scope of can accepting, but for SCR (Sequential color recapture) colour wheel, because it must accurately be aimed at light harvesting post (Light Integration Rod), therefore, existing fixed adjuster can't satisfy the alignment precision requirement of SCR colour wheel.
So, how to provide one can be accurately and fast be a big problem on the digital light projection machine is made in fact with SCR colour wheel and the fixing fixed adjuster of light harvesting post.In other words, how to provide a kind of the reduction to adjust degree of difficulty and have high precision that to adjust the fixed adjuster of effect be a big problem in fact.Because, when SCR colour wheel and light harvesting post are accurately adjusted fixing after, the whole image quality performance that will improve the digital light projection machine.
Summary of the invention
Because the problems referred to above, a purpose of the present invention provides a kind of SCR colour wheel and light harvesting post can being fixed, and can accurately adjust the optical element fixed adjuster of the relative position of SCR colour wheel and light harvesting post.
Another object of the present invention provides a kind of SCR colour wheel and light harvesting post can being fixed, and can accurately adjust the optical devices of the relative position of SCR colour wheel and light harvesting post.
Yet, feature of the present invention is to fix one first optical element and one second optical element respectively by one first binding member and one second binding member, and adjusts the relativeness of this first optical element and second optical element by the position of adjusting first binding member and second binding member.
For reaching above-mentioned purpose, comprise one first binding member, one second binding member, more than one first adjustment part, a socket element, one first pivot group, a retaining element, one second pivot group, reach a plurality of second adjustment parts according to optical element fixed adjuster of the present invention.First and second optical element is incorporated into first binding member and second binding member respectively.The socket element housing is connected to second binding member.These first pivot groups wear the socket element and second binding member respectively from the two opposite sides of socket element.Retaining element is formed with a smooth through hole.These second pivot groups wear retaining element and socket element respectively from the two opposite sides of retaining element.These second adjustment parts are arranged at respectively around the light through hole of retaining element, and wear retaining element and touch in the socket element.
In addition, comprise one first optical element, one second optical element, one first binding member, one second binding member, more than one first adjustment part, a socket element, one first pivot group, a retaining element, one second pivot group, reach a plurality of second adjustment parts according to optical devices of the present invention.First and second optical element is incorporated into first binding member and second binding member respectively.The socket element housing is connected to second binding member.These first pivots wear the socket element and second binding member respectively from the two opposite sides of socket element.Retaining element is formed with a smooth through hole.These second pivots wear retaining element and socket element respectively from the two opposite sides of retaining element.These second adjustment parts are arranged at respectively around the light through hole of retaining element, and wear retaining element and touch in the socket element.
