CV-SDTCM230-42 Industrial Far Heart Merroscopy Polarized/Polarized Mirror M56*P0.5mm eliminating reflection
Patent Number of the People''''''''s Republic of China:ZL202120138323.2(Counterfeit).
Step pitch 0.5mm , Three lock screws, new packaging boxes.
One end of polarizing mirror can be used to connect the lens, and the other end can be freely rotatedAngle angle, facilitates the glare generated by different angles, minimizes the glare,Provide flexibility and ease of use.
In the machine vision detection project, many surfaces of the tested special will emit a messy glare, these miscellaneous lights
It seriously affects the quality of imaging and reduces the contrast of the measured characteristics. In order to weaken or eliminate interference such as mixed light and glare, in many visual detection, measurement, and positioningEqualWhen building it is unified, we need to use polarizers in front of the camera.
Line partial vibration: After allowing natural light to pass a polarized device, there is only one direction polarized light that can pass this device, and we get the line polarizing light. The vibration direction of the line polarization is certain.
Round partial vibration: The polarization direction of this light is rotated regularly. The intensity of the optical vector in the process of rotation is maintained. That is, the light vector is rotating along a round. This is the round of light. After the average of our observation time period, the light of the round shock looks the same as the natural light. However, the polarization direction of the round vibration changes in accordance with certain rules, and the polarization direction of natural light changes is random and no regular.
The polarizing filter can eliminate the reflex light of the water, glass surface, and other non -metal surface, because the polarizing state of reflected light on these interfaces has changed.
【How to use polarizers】:
The polarizing mirror is usually composed of two iron rings. One iron ring can be installed in front of the camera. After tightening, it will not move, and the other is carried a glass. After the iron ring is tightened, it can still rotate freely. When using polarizers, we need to observe the reflection that needs to be eliminated in the viewfinder, and slowly rotate the front ring of the polarizer left and right.-The best rotation angle will soon disappear.
Polarizer Polarized mirror, also known as polarizing mirror, is a color filter. The excellent function of polarizing mirror is to choose from a choice to make a certain direction vibrate through. In color and black and white photography, it is often used to eliminate or weaken the strong reflection on the non -metal surface, thereby eliminating the reduction of light spots. Two pieces of optical glass sandwiched with a tiny polarized crystal crystal(Ru Yunmu)composition.
Simple explanation: It can be filtered out of reflection. Natural light is launched from the light source, and after reflection by the surface of the object, the attributes of the light have been secretly changed. We call this light polarized light. Human eyes cannot recognize the difference between polarization and natural light, so we cannot intuitive"See"This change. But polarizing mirror is like a filter. It allows natural light to pass, but it can intercept some polarized light, so that it can be artificially removed"Reflect"Impact.
