Nidek LM-7 Auto-Lensometer
More than dependable, beautiful Auto Lensmeter
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.
Hartmann Sensor with 108 Measurement Points
The LM-7 utilizes simultaneous measurement of 108 data points within the nosepiece. This advanced measurement principle allows faster and easier data acquisition with greater accuracy and reliability.
Green measurement light
Green light close to the ISO standard gives more precise measurement values without Abbe number compensation. The LM-7 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 determine the lens type. Automatically switching it’s measuring mode accordingly for a single focal lens, bifocal or progressive lens.
Scale Mode Function
Pupillary distance such as the LPD/RPD and 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.
5.7″ LCD Touch Screen
Full graphic vertical 5.7-inch color LCD with touch screen provides superior visibilty and simplified operation. The unique vertical design creates a sophisticated appearance and enhances functionality. Background color may be selected from many choices. The position of the graphics can be adjusted to accommodate the operators position.
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. Marco refraction products allow for quick and easy wireless data transfer using the Eye Care card, Bluetooth, WLAN or infrared communication. This is helpful for eliminating paper printouts and complicated wired connections.
