Simple lens filtering performance detection and display device

Abstract

The invention relates to a simple lens filtering performance detection and display device. The device is provided with a hollow display seat body, wherein a lens frame mounting seat and a lens frame are mounted in the display seat body, at least one strip-shaped hole allowing the lens frame to pass through is formed in one side wall of the display seat body, a detection light emitting circuit board and a detection light receiving circuit board are further arranged in the display seat body, and a side wall of the display seat body is further provided with a transmitted light indicating lamp corresponding to the detection light transmitting circuit board and a received light indicating lamp corresponding to the detection light receiving circuit board respectively. The device is advantaged inthat light with specific wavelength is emitted, the emitted light signal is received after passing through the to-be-detected lens, and the light signal is visually displayed and displayed in a modeof lighting or not after being processed and compared by a circuit, so filtering performance of the lens is rapidly detected and displayed, and convenience and reliability are brought to consumers toselect the lens.

Description

Technical field: [0001] The invention relates to the technical field of lens detection devices, in particular to a simple lens filter performance detection and display device. Background technique: [0002] Lenses need to filter light that is harmful to human eyes, such as ultraviolet light, harmful blue light, infrared light, etc. However, existing inspections often require professional inspection equipment with a very complex structure. Some illegal businesses use shoddy products and false propaganda to reject products that are not qualified. Or selling untested products to consumers, for consumers, not only costs money, but also uses harmful lenses, causing irreparable harm. In view of this, it is very necessary to design a simple, portable and low-cost detection device for consumers to choose or to intuitively show the filter performance of the lens to consumers, so that consumers can purchase qualified lenses and related products with confidence. Summary of the invention: ...
