【Quality Structure】

Resolution Detection

Each finished glass lens products will be tested with special HD testing equipment to ensure
excellent resolution.

Detection of Spectral Properties

BST uses spectrophotometer to test the spectral data of each batch of coated glasses, and monitors
the transmittance, reflectivity and other data.

External Assessment

BST has established a complete inspection system for image level optical lens.
From the appearance to the optical performance and physical strength of the lens, only the lens
that has passed all these tests is a qualified image level optical lens.

Performance Test Of Waterproof

BST lens provide double-sided of tri-proof property of coating and the water droplet angle can reach
110 ° after being tested by professional water droplet angle testing equipment.

Color Cast Test

With good neutral imaging, it will make the most comfortable visual impression of the lens.
BST uses the lens to take the standard color card to ensure that the RGB values interval difference
of images taken by the lens does not exceed ± 3.

Temperature Test

The reliability verification of the simulation lens in high temperature environment requires that the
optical property of the lens will not change after the test.

High Voltage Test

Each glass polarizer lens produced by BST will have constant voltage in high pressure environment,
so as to ensure that no degumming will occur of the glass polarizer lens .

Pressure Detection

The strength of glass lens is one of the important indexes of . BST quality testing room uses
professional pressure tester to test large lenses.

Drop Ball Detection

The BST quality testing room is equipped with special ball dropping equipment, which is tested
according to the requirements of corresponding standards.

Brine Boiling

BST quality laboratory for the coating layer of glass lens will be tested with high temperature brine
boiling and the Hundred Grid experiment, it is simulated in extreme use environment, and the glass
surface coating layer is guaranteed to not fall off.

Detection of Coating Layers Strength

BST quality testing room uses pencil hardness tester to test the strength of lens surface film.
