About our CPL products

1. We are using Japan's Nitto polarizing film with a polarization degree of over 99%. The following is a

test comparison picture：

The BST polarizer rotates against the pattern on the display, the background pattern gradually becomes

darker, until it becomes completely black, the polarization degree is as high as 99.9%, and the reflection

effect is excellent.

Other brands of polarizers, when the lens is rotated to the darkest, the pattern on the display can be seen

through the lens, the degree of polarization is not enough, and the reflection is not completely eliminated.

2. Ultra-thin.

The thinnest BST polarizer can reach about 1.5mm (as shown in the above picture). If the customer needs

to be thinner, it can be polished again, but the strength is still unchanged, which can meet the falling ball

test and more than 128g.

3. Minimal color cast: Every piece of BST product has undergone strict color cast test. This test model is

to input the spectral curve of the lens into the RGB three primary color control template to see the deviation

from the center of the coordinate axis. The closer to the (0,0) center, the smaller the color shift.

The result shown in the RGB test template: The BST polarized lens is at the center of the coordinate axis,

indicating that there is basically no color cast.

4. High resolution resolution: Each lens of BST will be tested with a high-definition test instrument (equivalent

to a 550mm lens of a SLR camera), and it will be qualified if it shows OK according to the corresponding test

standard.

Conclusion: The BST test image is clearer, and the image is blurred than other brands.

Of course, BST CPL also has the advantages of water-proof, oil-proof and scratch-resistant coating.

We will make every product carefully
