All the standard features at a cost-effective price
The LM-500 incorporate a fashionable design and practicality to guarantee a quality lensmeter that suits any room design. The LM-500 can measure Standard & High index, Bifocal, Trifocal, Progressive and Prisms lenses. In addition it can also give measurement of hard and soft contact lenses.
Colour touch panel and customizable shortcut buttons
The 5.7 inch colour TFT LCD touch panel display provides a clear image with an easy-to-use customizable shortcut menu.
Simultaneous measurement of UV transmittance.
PD measurement
The LM-500 can accurately measure the UV (385nm) transmittance while also measuring the power of lens. By using PD mode, the LM-500 can measure interpupillary distance with automatic Right/Left detection.
Automatic switch system to CL mode
By using AUTO CL mode, once the nose piece for measuring contact lenses is set, the LM-500 automatically switches to the contact lens measurement mode.
