This Carson LT-10 Lighted LinenTest six-pack consists of 11.5x-magnification linen testers that are suitable for counting threads in textiles. Each are foldable, compact, and has an open base that is designed to be overlaid on a flat object. Features within the base can then be compared to the two scales printed on the base frame. The scales measure up to 3/8" or 10cm in 1/16" or 1cm increments respectively. Other small, recurring features can be effectively counted, such as circuits on a motherboard, as well as dots or lines when printing or engraving. Each loupe features a dual lens optic to enhance sharpness, minimize distortion, and reduce chromatic aberration. The optic is set within a focus wheel for adjustment to the user and a built-in LED light powered by three #392 batteries provides additional illumination when needed.
Plastic cases for each magnifier are included for storage and transport.
