Summary of the invention
In view of this, be necessary to provide a kind of mechanical-optical setup with better prism fixed form.
A kind of mechanical-optical setup, it comprises a housing and a prism.Described housing has a receiving space that is used to accommodate described prism.Described prism has first end face and second end face at least, and the inside surface of described first end face and described housing is fitted.Offer a plurality of holes and a plurality of groove on the inside surface that described housing and described prism fit, be communicated with by described a plurality of grooves between described a plurality of holes.Described prism sticks on the described housing by perfusion colloid in described groove.
With respect to prior art, mechanical-optical setup of the present invention directly offers hole and the groove that is interconnected on its housing, described groove is used to guide the flow direction of colloid, described hole is used for unnecessary colloid is overflowed outside, make colloid can be evenly distributed on the inside surface with the bonding housing of prism, avoid colloid to influence the optical property of prism.
Description of drawings
Fig. 1 is the exploded view of mechanical-optical setup of the present invention;
Fig. 2 is the exploded view at another visual angle of mechanical-optical setup of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention being done one specifically introduces.
See also Fig. 1 and Fig. 2, a kind of mechanical-optical setup 100 provided by the invention, it comprises a housing 10, a prism 20 and a pad 30.Described housing 10 is accommodated described prism 20, and described pad 30 is arranged between described housing 10 and the described prism 20.
Described housing 10 comprises loam cake 101, lower cover 102 and sidewall 103.Described loam cake 101, lower cover 102 and sidewall 103 form a receiving space 104 that is used to accommodate described prism 20, and described receiving space 104 has one and is used for the inside surface 105 that fits with described prism 20.In the present embodiment, described prism 20 is fitted on the inside surface 105 of described lower cover 102.Offer a plurality of holes 11 and a plurality of groove 12 on the described inside surface 105, be communicated with by described a plurality of grooves 12 between described a plurality of holes 11.Described prism 20 sticks on the described housing 10 by perfusion colloid in described groove 12.In the present embodiment, the quantity of described groove 12 is 5, and the quantity in described hole 11 is 4, forms right-angle triangle after described groove 12 is communicated with.Described hole 11 is through hole or blind hole, as is blind hole, and then it is extended with certain depth from described inside surface 105 to housing 10 outsides, and the part of described extension forms a space that is used to collect unnecessary colloid.In the present embodiment, described hole 11 is a through hole.After in described groove 12, pouring into colloid, the flow direction of described groove 12 bootable described colloids, unnecessary colloid can overflow housing 10 outsides by described hole 11, thereby makes the colloid distribution uniform, avoids colloid to flow on the light face of prism 20 and influences prism 20 performances.In the present embodiment, described colloid is a UV glue.
In the present embodiment, described prism 20 is a right-angle prism.Described prism 20 comprise a light entrance face 21, fully reflecting surface 22, light-emitting face 23, first end face 24 and with described first end face, 24 second opposed end faces 25.Described first end face 24 fits with the inside surface 105 of described housing 10, and described second end face 25 fits with described pad 30.
The material of described pad 30 is sponge or rubber.In the present embodiment, the material of described pad 30 is a rubber.Concrete, also being provided with one integrated recessed 13 on the described housing 10, the shape of described recessed 13 shape and described pad 30 is similar.Described recessed 13 is arranged on the surface relative with described inside surface 105.In the present embodiment, described recessed 13 is arranged on the described loam cake 101, and described recessed 13 end face extends to described receiving space 104 from described loam cake 101 beginnings.After putting into described prism 20 and pad 30, described recessed 13 end face and described pad 30 are fitted.Described recessed 13 and described pad 30 can prevent second end face 25 and described housing 10 rigid contacts of described prism 10.
In the time of need being glued to described prism 20 on the described housing 10, at first in the groove 12 of described housing 10, pour into colloid, then prism 20 is placed in the described receiving space 104, and first end face 24 of prism 20 and the inside surface 105 of described housing 10 are fitted.Before colloid does not solidify, adjust the position of described prism 20, make the photocentre of prism 20 meet the requirements.After the end to be adjusted, irradiation ultraviolet radiation makes colloid solidification on second end face 25 of prism 20.Described pad 30 is placed on second end face 25 of described prism 20 then, thereby makes described recessed 13 to be pressed together on fixed prism 20 on the described pad 30.
Mechanical-optical setup 100 of the present invention directly offers hole 11 and the groove 12 that is interconnected on its housing 10, described groove 12 is used to guide the flow direction of colloid, described hole 11 is used for unnecessary colloid is overflowed housing 10 outsides, make colloid can be evenly distributed on the inside surface 105 with the bonding housing 10 of prism 20, avoid colloid to influence the optical property of prism 20.
