Lens film firmness damp erosion experimental equipment and method

Abstract

The invention discloses lens film firmness damp erosion experimental equipment and method. The equipment comprises constant-temperature mechanisms, constant-humidity mechanisms, clamping mechanisms, abox, a handle and a box cover, wherein the box cover is installed above the box and is connected with the box through hinges, the handle is arranged above the box cover and is fixedly connected withthe box cover through screws, the constant-temperature mechanisms are arranged inside the box, the constant-humidity mechanisms are arranged below the constant-temperature mechanisms, and each clamping mechanism is arranged at one side of the corresponding constant-humidity mechanism. By the adoption of mutual cooperation of springs, connecting rods and non-slipping blocks, a lens is clamped between every two non-slipping blocks; since the non-slipping blocks are made of elastic materials, side faces of the lenses cannot wear; and due to the elasticity of the springs, every two opposite non-slipping blocks can pre-clamp one lens.

Description

technical field [0001] The invention relates to the technical field of lens film layer testing, in particular to a lens film firmness moisture erosion test equipment and method. Background technique [0002] The mirror coating has three layers: the outer anti-fouling film is to prevent dust and oil stains; the middle anti-reflection film is to improve the light transmission rate of the lens; the inner hard film is to prevent the lens from being worn and scratched. These three layers of coating will make the vision brighter, and it will not be gray in a dim environment, which indirectly relieves eye fatigue. [0003] The existing moisture erosion test of the film firmness of the lens usually needs to go through multiple steps and requires the use of multiple instruments, and the experimental method is relatively cumbersome; in addition, the existing instruments often directly put the lens on Putting it into the storage box will cause the bottom surface of the lens to contact...
