Description
Technical field
The utility model relates to it is a kind of can switch speed to be exceedingly fast, high precision obtains two multiplying power images
More multiplying power camera lenses of changeable reflecting mirror, belong to camera lens manufacturing field.
Background technique
Current commercial measurement camera lens, some fields need high-resolution to neglect field detecting, at this moment need large-numerical aperture
The camera lens of small field of view, some fields need in low resolution but once detect in large area, at this moment need to disappear the big view of numerical aperture
The camera lens of field.
But there is also some fields, and same machine vision equipment is needed to be provided simultaneously with large-numerical aperture small field of view/decimal
It is worth the big two kinds of functions of visual field in aperture, or this 2 kinds of modes can be switched with most time to adapt to the requirement of actual production detection.
Existing more multiplying power camera lenses, some is directly use traditional zoom camera lens, and benefit is continuous zoom, the disadvantage is that zoom
Device longevity short precision is poor；Some are more multiplying powers as mirror+mono- magnification objective combination, are divided using half-reflecting mirror, advantage is precision
Height, the disadvantage is that the time for exposure is elongated since light splitting causes energy to become very low, measuring speed is reduced.
Summary of the invention
Purpose of design: avoiding the shortcoming in background technique, designs a kind of more multiplying power camera lenses to solve the problems, such as this.
Design scheme: in order to realize above-mentioned purpose of design.The utility model proposes a kind of use, and reflecting mirror can be switched
More multiplying power camera lenses change the multiplying power of actual use by way of rapid switched mirror, do not lose to light energy, precision
High and switch speed is fast.
Tthe utility model system is by lens LENS mono-, LEN bis-, LEN tri-, reflecting mirror, photoelectric sensor one, side photoelectric transfer
The device composition of the composition of sensor two and mobile mirror.
LENS mono- and LENS bis- combines available multiplying power as the camera lens of A, and LENS mono-, reflecting mirror and tri- groups of LENS
The camera lens that available multiplying power is B is closed, the camera lens that multiplying power is A is large-numerical aperture small field of view, and the camera lens that multiplying power is B is fractional value
Aperture big visual field or on the contrary.
From XZ planar observation, when reflecting mirror with reflective state in the optical path when, reflecting mirror is located in LENS mono- and LENS bis-
Between, LENS tri- is located in reflecting mirror side (left side), and photographic subjects, that is, object plane is located at mono- lower section LENS, and photoelectric sensor one is located at
Bis- top LENS, photoelectric sensor two are located at tri- side LENS (left side).
When reflecting mirror is in removed state, object plane and photoelectric sensor one are conjugated, the light that 5 arbitrary point of object plane issues
Line passes through LENS mono-, as soon as directly through focusing on photoelectric sensor after LENS bis-, such photoelectric sensor is obtained with multiplying power A
The image of object plane is taken.
When reflecting mirror is in the state of reflection, object plane and photoelectric sensor two are conjugated, the light that object plane arbitrary point issues
Across LENS mono-, it is then passed through LENS tri- after reflecting mirror reflects, is focused on photoelectric sensor two later, such photoelectric sensor
The image of object plane is just obtained with multiplying power B.
Technical solution: a kind of more multiplying power camera lenses of changeable reflecting mirror, the following above and point for the reflecting mirror being obliquely installed
It is not lens LENS mono- and lens LEN bis-, lens LEN tri- is located at the side of reflecting mirror, and photoelectric sensor one is located at lens LEN bis-
Top, photoelectric sensor two are located at tri- side lens LEN, reflecting mirror be may exist or LENS mono-, LENS bis-, LENS tri-,
It being removed in the case that sensor one and sensor two are motionless, reflecting mirror is fixed on the mechanical device that can be moved it,
Or mechanical device of stationary mirror itself can be moved together with reflecting mirror.
The utility model compared with the background art, first is that can switch speed to be exceedingly fast, high precision obtains two
The image of a multiplying power；Second is that risen to if the reflecting mirror for adding other changeable states in systems three multiplying powers or
More than, greatly improve the performance of machine vision image acquiring device.
Detailed description of the invention
The structural schematic diagram of more multiplying power camera lenses of reflecting mirror can be switched in Fig. 1.
Fig. 2 is the coordinate schematic diagram of Fig. 1, Y be into paper, it is vertical with paper.
Specific embodiment
Embodiment 1: referring to attached Fig. 1 and 2.A kind of more multiplying power camera lenses of changeable reflecting mirror, the reflecting mirror 3 being obliquely installed
Following above and is lens LENS 1 and lens LEN 22 respectively, and lens LEN 37 is located at the side of reflecting mirror 3, photoelectric sensing
Device 1 is located at 22 top lens LEN, and photoelectric sensor 26 is located at 37 side lens LEN.Mono- 4 lower section lens LENS is object
Face.
Lens LENS 1 and lens LEN 22 combines the camera lens that available multiplying power is A.
Lens LENS 1, reflecting mirror 3 and lens LENS 37 combine the camera lens that available multiplying power is B.
The camera lens that multiplying power is A is large-numerical aperture small field of view, and the camera lens that multiplying power is B is the big visual field of small value aperture, or
It is on the contrary.
Embodiment 2: on the basis of embodiment 1, reflecting mirror 3 uses flat reflective mirror, once anti-by a piece of reflecting optics
On the left of directive, or by after multi-disc reflecting optics multiple reflections by the reversed left side of light.
Embodiment 3: on the basis of embodiment 1, reflecting mirror 3 uses reflecting prism, to the left by reflecting prism primary event
Side, or by after the inner surface or outer surface multiple reflections of single prism or combined prism by the reversed left side of light.
In above-described embodiment, reflecting mirror is to can reside in reflection light in effective optical path or be removed effective optical path not
Interference light, can make its in the optical path effectively reflection, can also remove away from optical path allow entire optical path become not by
The optical path of interference being directed through.
Reflecting mirror removes, and can be along approximation or is equal to Y direction to moving away from light inside or outside paper
Road, can also be by way of some overturnings away from optical path.
It is to be understood that: although above-described embodiment contrasts detailed text to the mentality of designing of the utility model
Description, but these verbal descriptions only describe the simple text of the utility model mentality of designing, rather than practical new to this
It is practical new to each fall within this for the limitation of type mentality of designing, any combination, increase or modification without departing from the utility model mentality of designing
In the protection scope of type.
