QL-20

380 x 225 x 75 mm
15 x 9 x 3 in

With more than double the image area of 14 inch systems, the floor-model QL-20™ Contour Projector® is an outstanding value. It has a 20" viewable screen, rigid construction for measurement stability, and patented optics for visual acuity.

The QL-20 is designed to provide large measurement capability in a minimum amount of space. Controls are ergonomically located at natural positions for fatigue-free operation and the screen and digital readouts are located at eye level. The Ql-20’s in-line design allows easy access to parts and fixtures.

High-quality optics means that images are fully corrected (upright and un-reversed), with virtually zero distortion or field curvature. Diffraction-limited optics assure the sharpest images.
