Magnify and measure in one operation. Two lenses provide distortion-free viewing. This loupe includes a general purpose scale that measures circles from 0.002" to 0.0625"; radii from 1/16" to 3/8"; angles up to 90° in 5° increments; lengths up to 0.5" in 0.005" increments; lengths up to 10 mm in 0.2 mm increments; and line widths from 0.016" to 0.250".

Optional thread accuracy scale measures the following threads per inch: 50, 32, 28, 24, 20, 18, 16, 14, and 8.

Let in maximum light to view details with greater clarity than traditional loupes. First designed for jewelers, these loupes also work well for quality control and inspection.

Loupes with a glass lens are less prone to scratches than those with a plastic lens, so they provide a clearer view over time. Loupes with a plastic lens are more lightweight and shatterproof than those with a glass lens.

Add a scale to 7X and 10X loupes to measure as you magnify. General purpose scales measure radii from 1/16" to 3/8"; angles up to 90° in 1° increments; lengths up to 1/2" in 0.005" increments; lengths up to 10 mm in 0.1 mm increments; and line widths of 0.001", 0.002", and 0.003". Protractor scales measure angles up to 360° in 1° increments. Inch scales measure up to 3/4" in 0.005" increments. Metric scales measure up to 20 mm in 0.1 mm increments.
