Introduction
Auto lens meter L890 full function
Auto lens meter L890s basic function
Main features:
Multifocal lens measurement
Automatic recognition, rapid correction and positioning of far and near light zones, achieving precise measurement of parameters in various areas within an effective range
Hartmann has 145 sensing points, equipped with a high-speed and high-energy CCD camera, for fast, efficient, and accurate measurement without the need for Abbe parameter compensation
Strong strength and good stability, and long-term use will not cause any deviation
Main technical parameters
1. Green LED light source, no ABBE coefficient compensation required.
2. Automatically recognize and measure various lenses, quickly correct and locate the far and near light areas, and achieve precise measurement of parameters in various areas within the effective range (high refractive index, polarized light, high dispersion, etc.)Sunglasses, multifocal lenses, scratches, etc.
3. Measurement of pupillary distance and pupillary height: The display screen displays an electronic pupillary distance gauge, which can quickly and conveniently measure the pupillary distance and pupillary height installed in a mirror.
4. Using a 7.0 inch high-resolution touch LCD display
5. Transmission ratio of measurable lenses: ＞ 10%; When the degree exceeds ± 10m-1, the transmittance requirement of the lens is greater than 20%
Main technical parametersBall mirror: (0~± 25) m-1 (reading step size 0.01m-1/0.06m-1/0.12m-1/0.25m-1)
