Abstract
The utility model relates to the technical field of optical elements. A novel corner-cube prism comprises a corner-cube prism, wherein the corner-cube prism is provided with three right-angled reflecting surfaces, and the three right-angled reflecting surfaces of the corner-cube prism are respectively coated with an anti-reflection film layer. Through the novel corner-cube prism, the working precision of an optical precision measuring instrument can be improved, and the novel corner-cube prism is simple to manufacture and can be produced, popularized and applied in batches.
Description
Technical field
The utility model relates to optical element, particularly a kind of novel prism of corner cube.
Background technology
Prism of corner cube is a kind of total reflection prism, all will be reflected back by former direction efficiently for arbitrary incident ray that enters clear aperature.The precision of prism of corner cube is represented with the angular error of incident beam, by the orthogonal precision decision between three right angle faces.Prism of corner cube is widely used in all kinds of optical gauges such as telescope, microscope, spirit-leveling instrument, fingerprint instrument, firearms gun sight because of its characteristic.Along with the optics development of science and technology, common prism of corner cube can not meet the demands precision more and more higher all kinds of optical gauges and various imaging device.
The utility model content
Therefore, at above-mentioned problem, the utility model proposes a kind of raising measuring accuracy, make simple novel prism of corner cube.
For solving this technical matters, the utility model is taked following scheme: a kind of novel prism of corner cube, comprise prism of corner cube, and three right angle reflectings surface are arranged on it, three right angle reflectings surface of described prism of corner cube are coated with antireflective coating.
Further, described antireflective coating is a magnesium fluoride thin layer.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the utility model adopts anti-reflection film to reduce or eliminate the reflected light on reflecting surface surface, prism of corner cube right angle, thereby increase the light transmission capacity of these elements, reduce or eliminate the parasitic light of system, and then improve the measuring accuracy that uses prism of corner cube to obtain.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
With reference to figure 1, preferred a kind of novel prism of corner cube of the present utility model comprises prism of corner cube 1, and incident minute surface 11 and right angle reflecting surface 12 are arranged on it, and wherein three right angle reflectings surface 12 all are coated with antireflective coating, and this antireflective coating is that a magnesium fluoride thin layer constitutes.
Antireflective coating in the utility model also can be a mixed oxide thin layer, and this mixed oxide thin layer is made of alundum (Al, zirconium dioxide and three kinds of materials mixing of magnesium fluoride.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
