The QL-20 features a 20 in. diameter screen, while the QL-30 has a 30 in. diameter screen. The small footprint, vertical design of the QL systems allows large screen inspection in a relatively small spaceless than 17 square feet for the QL-20, and less than 20 square feet for the QL-30. Both machines offer large, bright images on a flat field screen for reduced operator eyestrain. Screen images are upright and unreversed, reducing visual confusion and aiding productivity.
