Abstract
The utility model discloses a simple optical detection device for lens thicknesses. The simple optical detection device comprises a focusing light source, a light source support, a light induction screen and an intelligent display screen. The focusing light source is fixed on the light source support, and the light source support is vertically fixed on the left of the light induction screen which is electrically connected with the intelligent display screen. According to the simple optical detection device for lens thicknesses, measuring points on lenses can be located accurately, and an optical refraction principle is used for accurately measuring lens thicknesses, so that defects of poor locating and low accuracy of traditional calipers measurement modes are overcome.
Description
Technical field
The utility model belongs to glasses and manufactures field, relates in particular to a kind of easy lens thickness optical detection apparatus.
Background technology
The mode that traditional lens thickness adopts vernier caliper directly to measure, but due to monoblock lens thickness incomplete same, location survey puts that required process is long and error of measured data is large, therefore, needs a kind of high precision eyeglass proving installation of accurately location survey point.
Summary of the invention
The purpose of this utility model is to provide a kind of easy lens thickness optical detection apparatus.
The technical scheme that realizes above-mentioned purpose is: a kind of easy lens thickness optical detection apparatus, comprise focused light source, light source bracket, photoinduction screen and intelligent display screen, wherein, described focused light source is fixed on the top of described light source bracket, described light source bracket is vertically fixed on described photoinduction screen left side, and described photoinduction screen is electrically connected to described intelligent display screen.
The utility model device can be located the measurement point on eyeglass accurately, and the applied optics refraction principle measures lens thickness accurately, has solved traditional slide calliper rule metering system poor location, defect that precision is low.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described.
Please refer to Fig. 1, the easy lens thickness optical detection apparatus of the present embodiment, comprise focused light source 1, light source bracket 2, photoinduction screen 3 and intelligent display screen 4, wherein, focused light source 1 is fixed on light source bracket 2 tops, shielding 3 angles with photoinduction is 45 °, and light source bracket 2 is vertically fixed on horizontal reflection level crossing left side, and photoinduction screen 3 is electrically connected to intelligent display screen 4.
The utility model principle is: in the situation that photoinduction is shielded on 3 without eyeglass, focused light source 1 emission of light, ray cast is x0 to the incident point on photoinduction screen 3, on photoinduction screen 3, kept flat in the eyeglass situation, focused light source 1 emission of light needs on Thickness Measurement by Microwave point to eyeglass, the incident point projected again after the eyeglass refraction on photoinduction screen 3 is x1, obtaining refraction angle according to the glass for lenses characteristic is a, recording distance between x0 and x1 is L, the measuring point lens thickness H of institute, according to refraction principle, L=H * tg45 °-H * tg (45 °-a), can calculate H=L/ (1-tg (45 °-a)).
Below the utility model is had been described in detail, those skilled in the art can make the many variations example to the utility model according to the above description in conjunction with the embodiments.Thereby some details in embodiment should not form restriction of the present utility model, the utility model will be usingd scope that appended claims defines as protection domain of the present utility model.
