Abstract
The utility model relates to the field of planar optical technologies, in particular to an optical digital display prism for an optical path in an optical instrument. The optical digital display prism is characterized in that: the prism is of a trapezoidal structure and comprises an upper plane, a lower plane, an inclined plane and the other inclined plane, an included angle alpha between the inclined plane and the lower plane is equal to 60-70 degrees, and an included angle beta between the other inclined plane and the lower plane is equal to 30-40 degrees. Compared with the prior art, the optical digital display prism is simple in structure, low in cost and long in service life, can be widely applied to optical instruments, and has a 35% wide visible view angle, a high light gain effect and a light-softening effect, the optical nonuniformity generated by a light-plane light source is avoided, and the optical digital display prism has an energy-saving function.
Description
Technical field
The utility model relates to the plane optical technical field, specifically a kind of optics digital display prism that is used on the optical instrument light path.
Background technology
The optical frames of present domestic use is to utilize optical total-reflection and refraction effect mostly, and in-plane scatter light is carried out polymerization to a certain degree, and its brightness effects is poor, and the light of total reflection is not recycled, and energy resource consumption is big.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of optics digital display prism is provided.
In order to achieve the above object; The utility model has designed a kind of optics digital display prism; It is characterized in that: this prism is a trapezium structure; Comprise plane, lower plane, inclined-plane and another inclined-plane, the angle of inclined-plane and lower plane is α=60～70 °, and the angle of another inclined-plane and lower plane is β=30～40 °.
The utility model is compared with prior art, and is simple in structure, and cost is low, and long service life can be widely used in the optical instrument; Not only have 35% wide visible visual angle, high gain of light effect, and have the sheen effect, avoid optics inequality property, and have energy-conserving action by the generation of light area source.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the stereographic map of the utility model.
Referring to Fig. 1 and Fig. 2,1 is last plane; 2 is lower plane; 3 is the inclined-plane; 4 is another inclined-plane.
Embodiment
Combine accompanying drawing that the utility model is further specified at present.
As depicted in figs. 1 and 2, the utility model is a trapezium structure, comprises plane 1, lower plane 2, inclined-plane 3 and another inclined-plane 4, and during best enforcement, the angle of inclined-plane and lower plane is α=70 °, and the angle of another inclined-plane and lower plane is β=35 °.The utility model can obtain producing light refraction at two-dimensional directional at least, so that produce good optically focused phenomenon, and has energy-conserving action.
