ALM 500 / ALM 700

Overview

The ALM 500 and ALM 700 are automatic lensmeters for optometrists, opticians and optical workshops. They measure single vision, multifocal and progressive lenses in frames, plus soft and hard contact lenses, quickly and accurately. Place the lens on the support and the lensmeter detects the lens type, guides you to centre it and confirms the measurement automatically. Both models share the same optical core. The ALM 700 adds UV transmission measurement, interpupillary distance measurement and a touch screen.

Green light for precise readings

Both lensmeters measure with a green light beam at 525 nm, similar to the ISO 7944 reference wavelength. This reduces measurement drift caused by light deviation through the lens, so every material is measured precisely and independently of its Abbe number. You never need to look up or enter the Abbe value.

• Sphere from -25.00 D to +25.00 D
• Cylinder up to ±10.00 D
• Prism up to 10 prism dioptres
• Tinted lenses up to class 4

Extended measuring capacity

The lens support adapts to all lens and frame curves and suits high base curves. The wide space under the base leaves room to position frame temples easily. The marking system is designed so that blocking and marking happen in one single operation, saving a step at the bench. A dedicated support is supplied for contact lenses, and the adjustable frame rest with a graduated scale gives a quick reading of the right and left eye height difference.

ALM 700 extras: UV and PD

The ALM 700 measures UV transmission (375 nm, UV-A) at the same time as lens power, with no extra handling. Both results show on the main screen. It also measures half and full interpupillary distance from 45 to 85 mm, using two independent nose supports. A reactive touch screen, similar to a smartphone or tablet, replaces button navigation.

Both models have a tilting colour screen for seated or standing use, a central validation button, an integrated printer, built-in accessory storage and quick-change marking tips.
