Film.
Further, the two right angle mirror polish, the inclined-plane are not polished.
Further, two right-angle surfaces are coated with anti-reflection film.
Further, the acute angle portion being located at beyond propagation path of the prism is down flat angle.
To solve above-mentioned second technical problem, the technical solution of the utility model is：
A kind of prism system, including the first prism and the second prism, first prism are light beam entrance prism, described
Two prisms are beam exit prism；First prism is above-mentioned prism；Second prism is right-angle prism, described second
Prism includes an inclined-plane and two right-angle surfaces, and a right-angle surface of second prism is beam incident surface, and inclined-plane is light beam
Exit facet；Or the inclined-plane of second prism is beam incident surface, a right-angle surface is beam exit face.
After employing above-mentioned technical proposal, the beneficial effects of the utility model are：
Because prism of the present utility model is right-angle prism, including an inclined-plane and two right-angle surfaces, in two right-angle surfaces
One right-angle surface is beam incident surface, and another right-angle surface is beam exit face, total reflection film is coated with inclined-plane, by changing light
The incident angle of beam, or the angle between inclined-plane and right-angle surface, can realize light beam one direction arbitrary proportion expand and shrink beam.
Because prism system of the present utility model includes the first prism and the second prism, the first prism is light beam incidence rib
Mirror, the second prism are beam exit prism；First prism is above-mentioned prism；Second prism is right-angle prism, the second prism bag
An inclined-plane and two right-angle surfaces are included, a right-angle surface of the second prism is beam incident surface, and inclined-plane is beam exit face；Or the
The inclined-plane of two prisms is beam incident surface, and a right-angle surface is beam exit face, and incident beam changes light after the first prism
The direction of beam and the width in x directions or y directions, it can further change direction and y directions or the x of light beam after the second prism
The width in direction.
In summary, a kind of prism of the present utility model and the prism system provided with the prism can realize that light beam arbitrarily compares
Example expand and shrink beam.
