The utility model has adjustable light intensity; the light source is replaceable; simple structure, convenient use, high integration level and small size.
Description
Technical Field
The utility model relates to an optics field, concretely relates to parallel light produces device is applicable to the light conversion that diverges that produces the pointolite and is the parallel light.
Background
A collimator is an optical instrument that can produce parallel light beams, and generally consists of a light source, a ground glass plate and a lens. The ground glass plate is placed at the focal plane position of the lens, the uniformity of non-uniform divergent light emitted by the light source is improved after passing through the ground glass, the divergent light projected by the ground glass at the focal plane position of the lens is changed into parallel light beams through the lens, and division patterns are also made on the ground glass when necessary and used for optical calibration. The collimator has various focal lengths to choose from. However, in the field of ammunition detection requiring simple parallel light, a parallel light generating device with small size and small focal length is required, the light intensity is expected to be adjustable, light sources with different wavelengths are expected to be replaceable, and the collimator is complex and inconvenient to use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a parallel light produces the device to the required parallel light in ammunition detection area, provides a parallel light produces the device.
The above object of the utility model is realized through following technical scheme:
the utility model provides a parallel light produces device, includes the barrel, has set gradually light source seat, orifice plate, light ring adjustable ring and camera lens in the barrel, is provided with the light source on the light source seat, and the drive power supply who is connected with the light source installs at the barrel lateral wall, is provided with logical unthreaded hole on the orifice plate, and the orifice plate setting is on the focal plane of camera lens, and the barrel outer wall passes through the support and is connected with the fixing base.
The clear aperture as described above is located at the focal point of the camera lens.
The light source seat is made of organic glass.
Compared with the prior art, the utility model, have following advantage:
1. the light intensity is adjustable;
2. the light source is replaceable;
3. simple structure, convenient use, high integration level and small size.

Detailed Description
To facilitate understanding and practice of the invention by those of ordinary skill in the art, the following detailed description of the invention is provided in connection with the examples, which are intended to illustrate and explain the invention and not to limit the invention.
Example 1
As shown in fig. 1, a parallel light generating device, includes barrel 3, has set gradually light source seat 4, orifice plate 6, light ring adjustable ring 7 and camera lens 8 in barrel 3, is provided with light source 5 on the light source seat 4, and the drive power supply who is connected with light source 5 installs at the barrel 3 lateral wall, is provided with logical unthreaded hole on the orifice plate 6, and orifice plate 6 sets up on the focal plane of camera lens, and barrel 3 outer wall passes through support 1 and is connected with fixing base 2.
The light source 5 can be selected to radiate light sources with different wavelengths according to requirements, the light source 5 is fixed on the light source seat 4 made of organic glass materials by using screws, and a driving circuit or a driving power supply for driving the light source 5 can be arranged in the barrel 3. The light beam emitted by the light source 5 penetrates through the light through hole on the pore plate 6, the light source 5 and the light through hole form small hole imaging, and the light beam output through the light through hole is used as a light source of the camera lens 8. The aperture plate 6 is located at the focal plane of the camera lens 8, and light transmitted through the light passing aperture of the aperture plate 6 will be converted into parallel light beams by the camera lens 8.
The position of the aperture plate 6 is determined by the focal length of the camera lens 8, the aperture plate 6 being located at the focal plane of the camera lens 8.
The diameter of the light through hole on the pore plate 6 is determined according to the light intensity of the required parallel light beam, and the larger the diameter of the light through hole is, the larger the light intensity is, the lower the parallelism of the light beam output by the camera lens 8 is; the smaller the diameter of the light-passing hole, the smaller the light intensity, and the higher the parallelism of the light beam output by the camera lens 8.
The light intensity of the light beam output by the camera lens 8 can also be adjusted by the aperture adjusting ring 7.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
