CPL Polarizer

CPL Polarizer Also known as Circular Polarizer ， Circle Polarizer ， It's mainly used to suppress non-compliance. Metal A strong reflection of the surface. （ Diagonal light ）， Show the colour and the sense of the object ， Even the color seems more saturated than the eye can see. ， It also helps to improve the sound and tone of the sky. ， is Most common efficiency filters 。 Definitions Polarizer From two pieces Optical Glass It's a small, luminous crystal that's directed. （ Like a cloud mare. ） Composition 。 There's another way to make it. ， Two. Optical Glass The layers between them are coated with polyethylene membrane or polyethylene cyanide, etc. ， This polymer coating can produce very fine fence structure. ， I think so. is A fine fence. ， Only the same light that passes in the direction of vibration and the same crack is allowed. 。 And two more. Glass They're all in a circle that can be rotated. ， By rotating one of them Optical Element It removes the polarized reflection of the surface of the object being taken. 。 This coating will be ageing and failing. ， And it's stifling. 、 Impacts and vibrations can reduce the useful life. 。 Role It's different from the filtering of the oscillation. ， Polarizer You can divide it into circles. Polarizer （ Abbreviations CPL） And linear Polarizer （ Abbreviations LPL） Two. ， The two roles. is Same 。LPL It's used mainly for old-fashioned manual focal cameras. ， This filter has been eliminated. 。 Late. CPL One more layer. 1/4 Wavelength Thin Film of ， This film has a special character. ， It can be in one direction. （ Assumptions x） The oscillation vectors produce π/2 Move ， And it's going in a vertical direction. （ Assumptions y） The vectors don't work. 。 So it can give the above-mentioned diaphragms a shivers. x and y The angle is passing through the split line. 1/4 Waveplate ， on is Just light up. is One set has two oscillations vertically. ， Phase difference π/2 The shivers are fusion. ， Just... is So-called round oscillation. 。 This design makes it more suitable for new automatic focus and automatic exposure cameras. 。 And so... , Adopt AF Lens ( Switch camera for automatic focus function Lens ) Camera ， Use both CPL As Polarizer 。 In some light. ， Linearity Polarizer It's possible to mislead the light elements in the machine for light detection. ， And so... DC And most auto-focused cameras use circles. Polarizer 。 PL The mirror. is Filter reflector ， Add image contrast 。 The working principles is Selectively filter light from one direction 。 By filtering many oscillations in the varnish reflection ， It reduces the intensity of light in the sky. ， Keep the sky dark. ， And add to the contrast between the sky and the clouds. 。 During Shooting Look Through the Viewfinder and Rotate the Front Optic ， The most visible effect of the viewer when the sky is darkest ， The Darkest and the Brightest 90 degrees 。 You can move to any angle between the darkest and brightest. 。 PL The mirror can also be effective in weakening or eliminating Africa. Metal Reaction on the surface ， This reflection. is Typical # The oscillation of the light # （ Metal No light reflecting back on the surface. is Diagonal light ， Polarizer It doesn't work for it. ）， By adjustment Polarizer You can filter out the reflection of this part. ， And thus improve the quality of the object. ， And to improve the clarity of the picture 。 For example: ， By Usage Polarizer ， It's a reflection that can reduce the surface. ， So we can clearly film the fish in the water. 。 In the shooting of a scene like this ， The light source's projection angle is aligned to the camera's photometric angle. ， And... Maximum The angle of the deviation is to be between 30～40 Between degrees 。 You can use it slowly by moving the filter front. Optical Element To adjust. ， Try to minimize the reflection of the landscape surface. 。 And... ， Polarizer It can effectively increase the saturation of colour. ， Increase Contrast ， Here. is Because... Polarizer It absorbs all directions of fog or dust reflected in the atmosphere. ， So that the images are purer. 。 For example: ， In the photograph of the flower stills and so on. ， Used frequently Polarizer To take a colorful picture. 。 In the view. 、 They're useful in the photographing of flowers and in the photographing of certain specific reflections that are more powerful. 。 Polarizer It's used in the viewing. ， The picture of the cloud has been extremely effective. 。 The blue sky has a greater refraction than the light that is scattered by the white cloud. 。 Utilization Polarizer It also saturates the colour of the green leaves and removes the fog from the low angles of the city's scenery. 。 Polarizer By Optical Element The main body and a recoiled frame connected to it ， Optical Element The main object is a tiny crystal. Glass Composition Grating 。 When rotating ， Polarizer It's... Grating The diagonal light that doesn't parallel it. 。 And so... ， Polarizer It controls and selects the reflections that record parallel to it. （ This reflection is a partial vociferation. ） Number 。 That's it. is Polarizer Can eliminate or diminish Africa Metal The way the surface reflects. 。 But most of them... Polarizer It's a little blue. 。 During Use and Photography It Also Blocks the Portion of Unpolarized Light Oscillating in the Same Direction as the Polarized Light 。 To avoid the image being too flat. ， Usually, you have to add more than one layer of exposure. 。 Our advantage. ： 1、 Filter Process Leader 。 2、3 Year Filter OEM Pay-up quality 。 3、 Imports used Polarizer Process ， Double Sided Coating Process 。
