The QL-30 Contour Projector is a floor model optical comparator from Optical Gaging Products that features a 30" diameter screen, while its small footprint and vertical design allows large screen inspection in a relatively small space—less than 20 square feet. The projector projects large, bright images on a flat field screen for reduced operator eyestrain. Screen images are upright and unreversed, reducing visual confusion and aiding productivity.

Designed for continuous use, the system ergonomics are excellent. Controls are in natural positions, easily at hand for fatigue-free operation. The bright screen and digital readout display is located conveniently at eye level, making it easy to visually scan back and forth between them, the company says. The inline design of the worktable provides operators with easy access to mounted parts and fixtures.

The machine's lenses are collimated and telocentric in design, ensuring image accuracy and an image size that does not change when the focus changes. The optics are precisely ground, coated and mounted for optimal image quality, durability and long operating life.

The list of standard features includes an integral geometric measuring processor with easy-to-read dual LCD displays and easy-to-reach, shop-hardened keypad. It includes tools to measure angle, radius, diameter, width, intersection, included angle, distance, roundness and straightness. An internal turret with automatic lens sensing provides for error-free measurement scaling with every magnification change. The heavy duty, high precision 32" x 8" nickel plated worktable can easily support 550 pounds (250 kg). DC servo variable-speed motor drive with joystick control delivers smooth, quiet, fast worktable motion, and allows for automatic operation with optional computer and software.
