NO. 1 progressive die series
A patent for invention: gradual more focus lens mold series is the product of my company's invention patent invention for my company director, chief technology officer, Dr QiuGuFeng.
Name of invention: gradual more focus lens
The patentee: jiangsu st. spectral optical technology co., LTD
Patent no. : ZL 2015 10675301.9
Licensing: 07 31, 2018
Technical features:the invention discloses a kind of based on hyperbolic tangent function and logarithm function of gradual more focus lens and its design method. Technical solutions are: to construct a hyperbolic tangent function to carry on the meridian design, through the control function of pan and zoom factor, can freely control in the area, the low beam position and the length of the channel; Build special logarithmic function of the lens on the luminosity distribution is defined, the lens design steps are simplified, with less amount of calculation, the effect of save design time, at the same time, also ensure the two sides of the low astigmatism, for personalized gradual provides the high quality of the lens design method.
Product features:1, the designed product far, give attention to two or morethings, close function, comfort, comfort and vision effect.
2, optical quality, the products of high precision, durable, the free surface machining technology and scientific production system.
3, can be provided according to the requirements of each channel, all kinds of functional design, design of left and right eye, eccentric design, also can provide the mould according to customer's sample, the lens samples to optimize design, more than 95% similarity.
Product range:our company can provide all kinds of inner surface and outer surface gradually mold, can design according to the customer's requirements: fatigue resistance gradual, youth gradual, middle-aged and old gradual, universal gradual, reading, office gradual, outdoor sports gradual, driving progressive, duplex gradual steps of mould and so on. (the left eye, design, around eyes eccentric design, left and right eye no eccentric design personalized design)
