The LM-7/7P series has established a new standard in automatic lensmeter equipment by Marco. Both the lensmeters design and user interface have been improved for simplified operation to expand the utility of the instrument while maintaining the auto lens measurement principles, functionality, and quality. Experience the digital lensmeter that combines aesthetic beauty and rugged dependability for your facility.
FEATURES
Auto Lens Type Detection: Placing the lens on the nosepiece activates the auto lens type detection to automatically determine the lens type – not only for single focal lenses but also for multifocal lenses – switching its measuring mode accordingly for a single focal lens, bifocal or progressive lens.
Scale Mode Function: Both monocular and binocular pupillary distance (PD), can be measured easily by aligning the marked glasses to the scale displayed on the screen. Screen color can be changed to black or white depending on marking color for greater visibility.
UV Transmittance Measurement: UV transmittance is presented as an intuitive display from 0 to 100% of central wavelength 365 nm (UV-A) in 1 or 5% increments. Comparison of two lenses can be easily displayed.
Hartmann/Shack Sensor: An advanced measurement principle, that incorporates simultaneous measurement of 108 data points within the nosepiece, provides greater accuracy and reliability with easier and faster measurements.
5.7″ Vertical Touchscreen: A 5.7-inch 640 x 480 dots touch screen achieves ideal layout display, superior in operation and visibility. Unique vertical design gives a sophisticated impression and greater function. Moreover, you can choose a favorite background color from many choices.
Data Management: The LM-7 series has one RS-232C port and two USB ports as standard. Optional LAN / WLAN connections are also available, which greatly expand data communication capability.
High-Speed Line Printer: The LM-7P features a high-speed printer with easy to read printouts. Measurement data is simply and logically presented for easy explanation.
