CN105738076A - Two-hole and one-support type computer lensometer - Google Patents

Abstract

The invention belongs to the optometric and spectacle selection instrument field and relates to a two-hole and one-support type computer lensometer. With the two-hole and one-support type computer lensometer adopted, the defects of inconvenient operation, large error, relatively low precision in glass and lens detection and measurement of an existing lensometer can be eliminated. Two-hole one-support spectacles and a lens detection mechanism which can be applied to the computer lensometer are provided. According to the technical schemes of the invention, two lens detection holes are correspondingly arranged according to the lens rings of a spectacle frame; the spectacles with two holes and nose pads are provided; and a lens detection support is provided. The spectacles or lenses are arranged on the support; and all detection data or detection points can be obtained with one step through an image sensor, a microprocessor ARM module, initial spot coordinates X-Y, center distance R, a transverse and longitudinal variable K, a central processor, an optical processor and a graphics target and are simultaneously displayed on a display screen.

Description

Holes one holds in the palm formula computer lens meter

Technical field: the present invention relates to optometry and join mirror instrument field, especially a kind of lens meter.

Background technology: one of mirror, Glasses detection instrument are joined in the optometry that lens meter is glasses retail shop and technical supervision, scientific research department's indispensability.Existing lens meter (1) when measuring glasses or eyeglass, on the detection hole of 1 diameter about 10mm, controls without planar member, and the levelness of manual control and adjustment glasses or eyeglass, spectacle frame or eyeglass and bottom stop plates not easily coincide.(2) detect by an unaided eye scale of moving playing surface, and it is relatively low that testing result is affected precision by the subjectivity of people, and also can produce abnormal prism degree.(3) use one detection hole operation trouble is detected about bottom stop plates null adjustment and eyeglass.(4) detection interpupillary distance and glasses optical center deviation, the vertical mutual deviation of optical center, the impact of the horizontal mutual deviation of optical center examined method is precisely not directly perceived.

Summary of the invention: in order to overcome existing lens meter troublesome poeration when detection measurement glasses and eyeglass, error is big, the deficiency that precision is relatively low.The present invention provides applicable holes one on a kind of computer lens meter to hold in the palm glasses, eyeglass testing agency.The technical solution adopted in the present invention is: be correspondingly arranged two eyeglass detection holes, the glasses having twoport and nose support, eyeglass detection holder according to the Jing Quan of spectacle frame.Glasses or eyeglass are placed in holder, by imageing sensor, microprocessor ARM module, initial hot spot coordinate X-Y, distance of center circle R, transverse and longitudinal variable K and center processor, optical processor, all detection data or test point one step are completed by figure target, and simultaneous display is on a display screen.The beneficial effect of the invention: (1) precision is high, simple and quick, functional by force.(2) numerical value being detected and some position are directly perceived, reproducible.(3) mirror or eyeglass is become to be placed in twoport detection holder, steadily stable, do not affected by external force and anthropic factor.(4) two, left and right eyeglass uses two detection holes respectively, and various association numerical value can synchronously complete very clear.(5) various non-standard glasses are detected more precisely reliable.

Detailed description of the invention: (being described in conjunction with the accompanying), in base (1) and detection hole slideway (4) upper installation eyeglass detection hole (3), two eyeglass detection hole parallel distances above can regulate in detection hole slideway (4).Detect hole (3) place suitable for reading at two eyeglasses, twoport detection holder (5) adjustable with facade main body (2) vertical interval is installed, and does the adjustment of fore-and-aft direction by detecting holder operation knob (6).One-tenth mirror or eyeglass are placed on twoport detection holder (5), it is close to along with edge, twoport detection holder (5) end at the bottom of mirror holder or eyeglass, two eyeglass detection holes are respectively aligned to twoport detection holder mouth center, left and right, and two eyeglass detection hole (3) spacing of easy adjustment and detection holder operation knob (6) just can complete inspection work.Mark printer structure (7) is fixed in facade main body (2), for franking on eyeglass.Display screen operating system (8) and display screen (9) are fixed in facade main body (2).Detection hole slideway (4) is arranged on base (1).

Claims (2)

1. A kind of holes one asks formula computer lens meter it is characterized in that:

   1. it is correspondingly arranged two eyeglass detection holes according to the Jing Quan of spectacle frame.
2. 2. it is provided above the glasses having twoport and nose support in detection hole, eyeglass detection holder.
