The Marco LM-7/7P auto lensmeter is the ultimate tool for precise and efficient lens measurements. Designed with the latest technology, it provides accurate measurements of power, cylinder axis, prism power, base direction, and displacement of all types of lenses. In addition to their superior aesthetics, Marco automated lensmeters are built for durability and reliability with a compact size that makes them the ideal choice for eye care professionals.
FEATURES
Shack-Hartmann 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.
Green Measurement Light: Green light close to the ISO standard gives more precise measurement values without Abbe number compensation. The LM-7/7P Instantly decides the direction of the reading point and detects the reading point immediately.
Automatic 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.
Prism Layout Function: Entering the prism prescription value in advance allows easy blocking of lenses at the prism prescription position by just following the target shown on the screen.
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.
Integrated Printer: The LM-7P model lensmeter features a high-speed line printer with auto cutter for easy to read printouts. Measurement data is simply and logically presented for easy explanation. Measured data can be output as QR code. By reading this QR code, the operator can input measured data into a PC. It can also be read by the NIDEK ICE-1200 Intelligent Blocker to prevent failure in processing.
