Abstract
The utility model relates to a reflection optical system for a barrier-free collimator, which comprises a main reflector, a second reflector, a third reflector and a fourth reflector; the second reflector is arranged on the reflection light path of the main reflector; the third reflector is arranged on the reflected light path of the second reflector; the fourth reflector is arranged on the reflected light path of the third reflector. The utility model provides a can shorten the light path of system, and the less long focus of the processing degree of difficulty of each speculum does not have the collimator that blocks.
Description
Technical field
The utility model relates to field of optical systems, relates in particular to a kind of reflective optics of blocking parallel light tube that is used to not have.
Background technology
Parallel light tube is the important tool that optical instrument is adjusted in the dress school, also is the important component part in the optics metering equipment, the graticule that adapted is different, together with the micrometer eyepiece head, or microscopic system, then can measure the focal length of high resolving power camera, image quality technical indicators such as resolution.Equipment such as adapted sun simulating light source, monochromator, moving target generator can be applied to detection, the optical system feature measurement of visible light camera imaging quality and survey in the characteristic staking-out work of receiving trap.
The spectral range broadness that reflective parallel light tube covers, to infrared, clear aperture is done greatlyyer easily from ultraviolet, therefore adopts reflective optics usually for wide-aperture parallel light tube.Common large aperture long-focus parallel light tube adopts coaxial optical system, there is central obscuration in system, make to there being central obscuration, and central obscuration is not comprehensive less than the detection of the camera of the central obscuration of parallel light tube, and adopt longer from two mirror system length of axle, and two catoptrons are that the primary and secondary mirror is aspheric mirror, and especially principal reflection mirror is the aspheric mirror from axle, and processing is difficulty comparatively.
The utility model content
The utility model is for solving the technical matters that exists in the background technology, shortens the light path of system and the less long-focus of difficulty of processing of each catoptron does not have the parallel light tube of blocking and provide a kind of.
Technical solution of the present utility model is: the utility model is a kind of reflective optics that is used for parallel light tube, and its special character is: described reflective optics comprises principal reflection mirror, second catoptron, the 3rd catoptron, the 4th catoptron; Second catoptron is arranged on the reflected light path of principal reflection mirror; The 3rd catoptron is arranged on the reflected light path of second catoptron; The 4th catoptron is arranged on the reflected light path of the 3rd catoptron.
Above-mentioned principal reflection mirror is rotational symmetric concave ellipsoidal surface catoptron.
Above-mentioned second catoptron is protruding spherical reflector.
Above-mentioned the 3rd catoptron is a concave spherical mirror.
Above-mentioned the 4th catoptron is a plane mirror.
The utility model has the advantages that:
1, can shorten the light path of system.The reflective optics that is used for parallel light tube provided by the utility model adopts four mirror systems, the compact conformation of system, parallel light tube to 30 meters focal lengths, with respect to two mirror systems in the background technology, the length of system can shorten one times, in 8 meters, and in the desired visual field of parallel light tube, system functional, the design wavefront difference also is better than two mirror systems in 0.03 wavelength.
2, the difficulty of processing of each catoptron is less.Principal reflection mirror of the present utility model is rotational symmetric concave ellipsoidal surface mirror, and second catoptron, the 3rd catoptron are spherical reflector, and the 4th catoptron is a plane mirror, and for two mirror systems needed off-centre, the difficulty of processing of system greatly reduced.
Description of drawings
Fig. 1 is a system light path synoptic diagram of the present utility model.
Embodiment
Referring to Fig. 1, the reflective optics that is used for parallel light tube that the utility model adopted has four catoptrons, and wherein principal reflection mirror 1 is the concave ellipsoidal surface catoptron, and second catoptron 2 is protruding spherical reflector, the 3rd catoptron 3 is a concave spherical mirror, and the 4th catoptron 4 is a plane mirror.Second catoptron 2 is arranged on the reflected light path of principal reflection mirror 1; The 3rd catoptron 3 is arranged on the reflected light path of second catoptron 2; The 4th catoptron 4 is arranged on the reflected light path of the 3rd catoptron 3.
The total system lateral length is in 8 meters, and longitudinal length is in 2 meters.And system can satisfy request for utilization in 0.1 ° * 0.1 ° big visual field.Focusing is longer than 10 meters, and the aperture of system is greater than 500mm, and the parallel light tube of the no central obscuration of requirement, especially at the parallel light tube of ultra-large aperture, overlength focal length, adopts reflective optics form advantage of the present utility model more obvious.
