753Measuring Magnifier, 15x测量放大镜

Measuring Magnifier, 15x

Metric

Inch

A wide-field magnifying glass of 15x magnifying power, combined with a graduated measuring scale. Similar to the 7x and 10x Scale Magnifiers. However, to allow the sharp observation of the entire field of a 14mm diameter object magnified 15 times, the magnifier has been designed to correct almost perfectly the curvature of field and the lateral chromatic aberration by a combination of 4 lenses in 3 groups. Provided with measuring scale: either 20mm in length with 0.1mm divisions, or 0.5" in length with 0.005" divisions. Scale diameter: 26mm （1"）. With case, lens cap and cloth.

一种15倍放大倍率的宽视场放大镜，结合了刻度尺。 类似于7x和10x刻度放大镜。 然而，为了能够对放大15倍的14mm直径物体的整个视场进行锐利观察，放大镜设计成通过3组中的4个镜头的组合几乎地校正场曲和横向色差。 提供测量刻度：长度为20毫米，分度为0.1毫米，或长度为0.5英寸，刻度为0.005英寸。 刻度尺寸：26mm（1“）。带表壳，镜头盖和布。
