Description

Rulers skiaskopichesky LSK-1 are intended for objective definition of a refraction of an eye. It is used in eye offices of policlinics, out-patient clinics and in eye offices of hospitals.


Rulers skiaskopichesky LSK-1 consist of two rulers with positive and negative lenses and have cursors, respectively, with positive and negative lenses.

In lines positive and negative lenses have the following values back top of a refraction: 1, 2, 3, 4, 5, 6, 7, 8, 9 dptr. The first nest of rulers has no lens. 

In cursors there are two nests with the designations "0,5" and "10".

In a cursor with positive lenses in a nest with the designations "10" there is a lens with back top of a refraction plus 9,0 dptr, in a cursor with negative lenses - minus 11,0 dptr that corresponds at an eye refraction skiaskopiya plus or minus 10 dptr. Thus, increase in distance from the patient's eye to a lens of cursors in comparison with lenses of rulers is considered. In nests with the designations "0,5" there are lenses the corresponding back top of a refraction.

On cursors there are two viewing openings through which the corresponding designations on a ruler are visible.

At combination of one of cursor lenses with a lens of a line of value of sizes of their refractions develop ( the corresponding designations on a cursor and a ruler are summarized).

At combination of lenses of a cursor with the designation "0,5" with the first free nest of a ruler the smallest refraction equal 0,5 dptr turns out.

At combination of lenses of a cursor with the designation "10,0" with ruler lenses with designation 9 the greatest refraction equal 19 dptr turns out.

Value of a refraction in the range from minus 9 to plus 9 dptr turn out with an interval 0,5 dptr, in other ranges - with an interval 1 dptr.
