Optical practices, dispensing counters and lens workshops use the CLE 60 to read the power of spectacle and contact lenses. Opticians, optometrists and workshop technicians operate it, and the readings inform dispensing, lens checking and the matching of new lenses to a prescription. Both dispensing areas and workshops are named as suitable settings.
The CLE 60 suits a counter that sees many kinds of lenses. It measures single vision, bifocal, trifocal and progressive lenses, and it identifies progressive lenses automatically, so the operator reads addition from the same lens. A counter that handles varifocal lenses can read them in the same routine as the rest. Sphere runs to ±25 D, cylinder to ±10 D and axis from 1 to 180°, with prism and Abbe number also available.
The tiltable colour screen can be angled for seated or standing use, and a self-sliding frame holder supports mounted lenses. Lenses up to 100 mm in diameter are accepted, and a dedicated holder takes contact lenses. Each result is recorded by the integrated thermal printer, and an RS232C output passes data to other equipment. Thermal paper for the printer is a listed accessory, so printed records can be kept at the counter.
The compact unit weighs 5.2 kg and measures 260 × 200 × 445 mm, so it fits a counter or a workshop bench. The power supply is multi-voltage, and the instrument complies with ISO 8598. Marking tips, a lens clamp, and a lens holder are available as accessories, which let a workshop mark and hold lenses on the same instrument.
