After face enters the 3rd triangular prism, this light beam by the 3rd reflecting surface total reflection after by this second light go out/
Entering face and entering this second triangular prism, then this light beam is sequentially by this pellicular front and this second reflecting surface
After by this first triangular prism, this light beam enters this roof prism, then this light beam sequentially by this
After one smooth in/out face, this ridge face are totally reflected with this first reflecting surface, by the injection of this first smooth in/out face.
Another embodiment of the optical system of the present invention includes: roof prism, the first triangular prism, second
Triangular prism, the 3rd triangular prism and light source.Light source sends light beam, and this light beam is not sequentially led to reflectingly
After crossing the 3rd triangular prism, this second triangular prism and this first triangular prism, enter this roof prism,
And leave this roof prism after the reflection of this roof prism.
In the optical system of the present invention, owing to arranging the 3rd triangular prism, from the light beam of light source by
Three triangular prisms are directly with the incident roof prism of default angle, it is not necessary to be extra adjustment, Ke Yijie
Save the time assembling and operation.
Brief description
In order to above and other objects of the present invention, feature and advantage can be become apparent, cited below particularly go out
Embodiment simultaneously coordinates accompanying drawing to elaborate.
Fig. 1 is the schematic diagram of known optical system.
Fig. 2 is the schematic diagram of the optical system of the present invention.
Detailed description of the invention
Referring to Fig. 2, it represents the optical system of the present invention.The optical system 1000 of the present invention includes light
The 200th, source focuses mirror group the 300th, roof prism optical system 400 and projecting mirror group 500.
Roof prism optical system 400 includes roof prism the 420th, the first triangular prism the 440th, the second triangle
Prism 460 and the 3rd triangular prism 480.Roof prism 420 has the first the 422nd, room, smooth in/out face
Crestal surface 424 and the first reflecting surface 426.First triangular prism 440 has the second reflecting surface 442 and thin
Face 444, the second reflecting surface 442 is adjacent to the first reflecting surface 426 and arranges.Second triangular prism 460 is adjacent
The pellicular front 444 being bordering on the first triangular prism 440 arranges and has the second smooth in/out face 462, the 3rd triangle
Prism 480 is adjacent to the second smooth in/out face 462 of the second triangular prism 460 and has the 3rd smooth in/out face
482 and the 3rd reflecting surface 484.
Light source 200 sends light beam L, and light beam L is incident with the state being parallel to the optical axis P of focusing mirror group 300
In focusing mirror group 300, and being adjusted focusing by focusing mirror group 300, then light beam L is from the 3rd smooth in/out face
After 482 entrance the 3rd triangular prisms 480, light beam L passes through the second light after being totally reflected by the 3rd reflecting surface 484
In/out face 462 and enter this second triangular prism 460, then light beam L sequentially by pellicular front 444 with
And second reflecting surface 442 with after by the first triangular prism 440, light beam L enters roof prism 420,
Then light beam is sequentially by the first smooth in/out face after the 422nd, ridge face 424 and the first reflecting surface 426 are totally reflected,
Being penetrated by the first smooth in/out face 422, then light beam L projects via projecting mirror group 500.
In the present embodiment, the 3rd triangular prism 480 is incorporated into the second triangular prism 460 in the way of binding.
In addition, light source 200 includes Organic Light Emitting Diode.Optical system 1000 amount of can apply to of the present invention
In examining system, the light that for example sends as the organic LED panel of light source 200 is via the light of the present invention
System 1000 projects, and user can watch the content of Display panel via projecting mirror group 500.
Although in the above-described embodiments, light beam L is adjusted focusing by mirror group 300 of focusing, but the present invention does not limits
In this, in another embodiment, the light beam L that light source 200 sends is by focusing mirror group the 300th, roof prism
After optical system 400 and projecting mirror group 500, it is also possible to projecting mirror group 500 is adjusted focusing.
So due to the 3rd triangular prism 480 and other optical module in roof prism optical system 400
Joining, the light making incidence can be via the after the 3rd reflecting surface 484 reflection of the 3rd triangular prism 480
Two triangular prisms the 460th, the first triangular prism 440 and roof prism 420 and incident projecting mirror group 500,
Therefore, when assembling, as long as allowing incident 3rd triangular prism 480 of light beam, no-mirror needs to adjust,
The man-hour of assembling can be shortened.
Though the present invention is disclosed above with embodiment, but it is not used to limit the scope of the present invention, the skill of this area
Art personnel, in the scope without departing from the present invention, when a little change and retouching can be done, therefore this
Bright protection domain ought be as the criterion depending on as defined in claim.
