Features
1. Using Hartmann multi point area measurement method to measure the progressive lens quickly and accurately.
LM-300 adopts each measurement result to participate in the amount of calculation which is higher than 80 point data, the progressive multi focal lens can be measured more accurately.
2. No need for Abbe constant, operation more convenient and measurement more accurate.
LM-300 adopts green LED light source which does not require Abbe constant compensation. Therefore, the operation is simpler and the measured data is more accurate.
3. Based on expandable integrated high speed processing system.
LM-300 adopts new expandable integrated high speed processing system, high speed image processing capability, operation capability of up to 4000 dmips. So that it can process the image quickly with a time of less than 80ms from collection to processing
4. Support for ultra-low transmittance and low dispersion lens measurement
LM-300 uses the built-in high-speed processing systems to enable the processing of image reception and data, optimization of system intelligence synchronization and accurate measurement of low-scatter lenses.
5. The upper limit of a prism is as high as 20Delta
The upper limit of LM-300 prism measurements is both 0 20 Delta in horizontal and vertical directions, with greater flexibility for measurement.
6. Automatic identification of lens type
LM300 is equipped with automatic identification system. The system automatically switches to the corresponding measurement mode according to the characteristic parameters of the measured lens (divided into the normal lens mode and the progressive multifocal measurement mode).
7. Support for PD, PH, UV measurement result printout
