Problems solved by technology
[0003] At present, most of the mirrors are molded with plastic as raw material. On the one hand, plastic is not resistant to high temperature and will soften and deform in high temperature environment. The low refractive index of plastic is not conducive to the transmission of light; on the other hand, plastic As the raw material, the one-word mirror directly pressed by the mold will leave roughness and other flaws, and it will leave traces when the flaws are removed by polishing.
These all affect the light transmittance of the straight mirror and the accuracy of using the straight mirror instrument
At the same time, the one-piece mirror made of plastic is inconvenient to assemble and the cost is relatively high

Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with specific embodiments.
[0017] The straight mirror 1 of the present invention is particularly suitable for the straight mirror 1 that laser semiconductor lasers use, and the mirror body 3 is a plane mirror, and the mirror body 3 can be processed into a plane lens of any shape. For the convenience of use and manufacture, the mirror body 3 is generally cylindrical, and can also be processed into square and other shapes. A semi-cylindrical mirror 2 is glued on the mirror body 3, and after bonding, the straight mirror 1 needs to be polished so that its edges have rounded corners.
[0018] The semi-cylindrical surface mirror 2 on the mirror body 3 can be provided with 1-10 pieces as required, such as figure 1 Shown, a piece of semi-cylindrical mirror 2 is bonded above the mirror body 3 of the straight mirror 1 in the figure, figure 2 The mirror body 3 of shown straight mirror 1 ' is bonded...

The invention discloses a rod lens comprising a lens body, the lens body is cylindrical, and semi-cylindrical lens are adhered above the lens body from the center to two sides. The number of the semi-cylindrical lens is 1-10. The rod lens is made of glass. The rod lens has simple structure, convenient assembly and lower cost. The glass can withstand high temperature, so the normal use of the rod lens which is made of the glass is not affected at high temperature. The glass has higher refractive index, good stability and good uniformity and the rod lens which is made of the glass has high lighttransmission rate and light is well spread. The rod lens solves the problems that plastic material can not withstand the high temperature, can not assemble with a rod lens conveniently and costs higher .
Description
technical field [0001] The invention relates to a straight mirror, in particular to a straight mirror used as an optical element. Background technique [0002] With the development of science and technology, optical instruments are widely used in various projects, and the straight mirror has been widely used as an optical component of optical instruments. For example, the straight mirror is used as a supporting component of the laser level ruler of the measuring tool in the field of construction and decoration industry. [0003] At present, most of the mirrors are molded with plastic as raw material. On the one hand, plastic is not resistant to high temperature and will soften and deform in high temperature environment. The low refractive index of plastic is not conducive to the transmission of light; on the other hand, plastic As the raw material, the one-piece mirror directly pressed by the mold will leave roughness and other flaws, and it will leave traces after polishin...
