LM-300 Low Price Optical Equipment Lensometer Digital Auto Lensmeter
LM-300 Auto Lensmeter
Features:
1.Using hartmann multi point area measurement method to measure the progressive lens rapidly
and accurately.
LM-300 adopts every measurement result to participate in the amount of calculation which is higher than 80 spot data, then 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 com-pensation. thus operation is
more simple and the measured data is more accurate.
3.Based on extensible integrated high-speed processing system.
LM-300 adopts new extensible integrated high speed processing system, high-speed image processing
ability, operation ability of up to 4000 dmips. With this, it can quickly process image with time less than 80 ms from
the collecting to processing
4.Support for ultra-low transmittance and low dispersion lens measurement
LM-300 makes full use of the integrated high-speed processing systems to make the processing of image receiving and data, system intelligence synchronization optimization, 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 are both 0 20 delta in horizontal and vertical directions,with greater flexibility for measurement.
6.Automatic identification of lens type
LM-300 is equipped with automatic identification system. The system will automatically switch to corresponding measurement mode according to the measured lens characteristic parameters (divided into normal lens mode and progressive multi-focal measurement mode).
