Description
Technical field
The utility model is related to photoelectric detection technology field, and particularly a kind of optical lens is as matter on-line detector.
Background technology
One lens assembling is completed, whether qualified, it is necessary to carry out image quality evaluation to it.Current optics corporate boss, which will utilize, to be divided
The image quality of resolution projecting apparatus and MTF detector two ways detector lens.Because MTF detectors are expensive and detection speed
Rate is slow, is generally not used for camera lens batch detection.And resolution projector is usually used in enterprise large quantities of due to cheap easy to detect
The Shot Detection of amount.Specific detection method is, in darkroom, and the tested camera lens of production is arranged on projecting apparatus, passes through quilt
Survey camera lens the resolving power test target inside projecting apparatus is projected on screen, then with eye observation screen the picture of resolving power test target it is clear
Whether, it is whether up to standard come the picture matter of judging camera lens.The shortcoming of mode of this kind detection is, in darkroom by eye-observation,
Detection is easy to fatigue for a long time, less efficient and influenceed by target contrast.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of optical lens as matter on-line detector, simple in construction, no
Personnel are needed to stay in darkroom observation.
The utility model is realized using following scheme：A kind of optical lens is as matter on-line detector, including is set in turn in
Resolution ratio detection projecting apparatus, imaging plate, photoelectricity testing part on same level axle, the photoelectricity testing part are electromechanical with calculating
Property be connected；The resolution ratio detection projecting apparatus is just provided with tested camera lens, the photoelectric detector to one end of the imaging plate
Part is just provided with detector lens to one end of the imaging plate；The imaging plate, detector lens, photoelectricity testing part are arranged at
In one cabinet；The cabinet is provided with a hole close to one end of imaging plate, to pass through the tested camera lens.
Further, the imaging plate is half-transmitting and half-reflecting and the small frosted glass of surface particles or thin paper.
Further, the resolution ratio detection projecting apparatus, imaging plate and photoelectricity testing part are arranged on by sliding block
On one high-precision guide rail, distance each other is moved horizontally and then adjusted on guide rail.
Further, the resolution ratio detection projecting apparatus includes light source, resolving power test target and power supply.
Further, the detector lens are that high-resolution, high pixel, short focus are focused or zoom lens.
Particularly, the photoelectricity testing part includes charge-coupled device and image pick-up card.
Preferably, in detection, the resolution ratio detection projecting apparatus on operating personnel's moving guide rail stretches the tested camera lens
Enter in the cabinet, send uniform light irradiation resolving power test target from light source, resolving power test target is illuminated as a light source, due to dividing
The distance of resolution plate to tested camera lens is equal to the focal length of camera lens to be measured, then be tested camera lens can by resolving power test target at infinity into
Picture, therefore imaging plate is moved to the position of about 15 times of lens focus to be measured（That is infinite point）Imaging, imaging passes through inspection
Lens imaging is surveyed on charge-coupled device again by image pick-up card by image transmitting to computer.
The utility model is simple in construction, it is not necessary to which personnel stay in darkroom observation.
Brief description of the drawings
Fig. 1 is principle schematic diagram of the present utility model.
Fig. 2 is the light path schematic diagram in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.

Resolution ratio detection projecting apparatus on trunnion axis, imaging plate, photoelectricity testing part, the photoelectricity testing part and the electrical phase of computer
Even；The resolution ratio detection projecting apparatus is just provided with tested camera lens to one end of the imaging plate, and the photoelectricity testing part is just
Detector lens are provided with to one end of the imaging plate；The imaging plate, detector lens, photoelectricity testing part are arranged at a machine
In case；The cabinet is provided with a hole close to one end of imaging plate, to pass through the tested camera lens.
In the present embodiment, the imaging plate is half-transmitting and half-reflecting and the small frosted glass of surface particles or thin paper.
In the present embodiment, the resolution ratio detection projecting apparatus, imaging plate and photoelectricity testing part are set by sliding block
Put on a high-precision guide rail, distance each other is moved horizontally and then adjusted on guide rail.
In the present embodiment, the resolution ratio detection projecting apparatus includes light source, resolving power test target and power supply.
In the present embodiment, the detector lens are that high-resolution, high pixel, short focus are focused or zoom lens.
Particularly, in the present embodiment, the photoelectricity testing part includes charge-coupled device and image pick-up card.
Preferably, as shown in Fig. 2 in the present embodiment, in detection, the resolution ratio on operating personnel's moving guide rail is detected
Projecting apparatus, the tested camera lens is stretched into the cabinet, and uniform light irradiation resolving power test target, resolving power test target quilt are sent from light source
Illuminate as a light source, because the distance of resolving power test target to tested camera lens is equal to the focal length of camera lens to be measured, be then tested camera lens meeting
Resolving power test target is imaged at infinity, therefore imaging plate is moved to the position of about 15 times of lens focus to be measured（That is infinity
Place）Imaging, imaging by detector lens be imaged on charge-coupled device again by image pick-up card by image transmitting to count
On calculation machine.
