The polarizing mirror is manufactured according to the polarization principle of light.The special effect of the polarizer is to effectively exclude and filter the scattered light in the beam.Make the light into the eye visual image in the transmittance of the light, making the field of view clear and natural.Like the principle of shutters, the light is adjusted to the same direction and enter the room, naturally makes the scenery look soft and not dazzling.Today, lets take a look at the role of polarizer and the difference between polarizer and sunglasses.
The role of polarizing mirror
The effect of polarizing mirror is to effectively eliminate and filter the scattered light in the beam.Make the light into the eye visual image in the transmittance of the light, making the field of view clear and natural.Like the principle of shutters, the light is adjusted to the same direction and enter the room, naturally makes the scenery look soft and not dazzling.
Specific to daily life:
1. When driving, it will no longer bother the many reflection from the sun and the vehicles in front;
2. When fishing, the water waves shine under the sun, but you will not feel uncomfortable at all, but feel comfortable and remote;
3. During skiing, you dont have to worry about reflective and ultraviolet rays, you can skate it.
4. When it rains, the road surface traffic signs with rainwater flow are clearly presented in front of you;
5. During vacation, let you enjoy the sun, beach and leisure time.
The difference between polarization and sunglasses
1. Different effects
Ordinary sunglasses are weakened into the eye with the color dyed on the dyed lens, but all glare, refraction light and scattered light enter the eyes, and cannot achieve the purpose of eye -catching.One of the role of polarizing lenses is to remove glare, scattered light, and refraction light. Only absorb the reflex light of the object itself, truly present the things to see, improve the drivers vision, reduce fatigue, increase color saturation, and the vision is clearer.It plays the role of eye -catching and eye protection.
2. Different principles
Ordinary dyeing lenses use the staining to block all light. What you see can change the color of the object. What color the lens is, what color the object is covered.Especially when driving it, it has a huge color difference in the recognition of the traffic lights, and it is seriously impossible to recognize the green light.Become a hidden danger of traffic.Polarized mirror is the principle of polarizing light, and what you see will not change color.The vehicle is driving at a high speed. After entering the tunnel, the light in front of the eyes of Diptong sunglasses immediately darkens, and the road in front of the eyes cannot be seen seriously, and polarizing mirrors will not have an impact.
3. Different degrees of blocking ultraviolet rays
Strong ultraviolet rays are human invisible killers. The polarized mirror is born for this. The blocking rate of ultraviolet rays reaches 99%, while the blocking rate of ordinary stain lenses is quite low.
Principles of polarizing mirror
The role of polarizing mirror is to filter reflective light and increase imaging contrast.Its working principle is to selectively filter light from a certain direction.By filtering the many spoilers of light in the long reflection, weaken the strength of the light in the sky, darke the sky, and increase the contrast between the blue sky and the white clouds.When you shoot the specific real shooting, you should look at the viewfinder and rotate the front mirror. The darkest effect in the sky in the viewfinder is the most obvious, and the darkest is 90 degrees.You can transfer to any angle of the darker and the brightest rooms as needed.Polarized mirror can also effectively weaken or eliminate non -metallic surface reflection. This reflection light is a typical polarizing light (the light reflected by the metal surface reflection is not polarized light, and the polarized mirror does not work on it). By adjusting the polarizer, you can filter it by adjusting the polarizer.The reflection of this part is dropped, thereby improving the image quality of the subject and improving the clarity of the picture.
For example, by using polarizers, the reflection of the water surface can be weakened to clearly shoot the fish in the water.When shooting such a scene, the projection angle of the light source should be consistent with the angle of the camera, and its maximum partial angle needs to be agreed between 30 and 40 degrees.When using it, you can adjust the lens in the front group of the filter to minimize the reflection of the surface of the scene.In addition, polarizing mirrors can effectively improve the saturation of color and increase contrast. This is because polarizing mirrors can absorb various directions reflected in the fog or dust reflected in the atmosphere, so that the shooting images are more pure.For example, in photography such as flowers and static objects, polarizers are often used to take colorful photos.It is useful when landscape photography, flower photography and shooting certain specific reflective scenes.The polarizer is used in the landscape photo, and the depiction of the cloud layer has excellent effects.The light refractive index of the blue sky is greater than the light scattered by the white clouds.Using polarizer can also make the color of green leaves more saturated and eliminate the fog of shooting urban scenery at low angles.
