1.1usage of instrument

DSR-LM300 auto focimeter is used to measure the vertex power, prism degree of glasses lens(including the cornea contact lens), to fix the cylinder axial direction of cylindrical lens, to print the marking on the uncut lens, to check whether the lens are stalled in the frames correctly. 

1.2 characteristic

◆ Delicate & modern products appearance and moulding with simple design

◆ Rotatable 7 inch colorful big touch screen

◆ Simple & convenient operation interface, brand-new human-machine interaction

◆ Using hartmann multipoint area measurement method to measure the progressive lens rapidly and accurately

◆ No need for ABBE constant, Operation more convenient and measurement more accurate

◆ Based on extensible integrated high-speed processing system

◆ Support for ultra-low transmittance and low dispersion lens measurement

◆ The upper limit of a prism is as high as 20 delta

◆ Automatic identification of lens type

◆ Support for PD,PH, UV measurement result printout

1.3 working environment

 The instrument should be installed and used under the below conditions.

◆ Environment temperature: ＋5℃～＋40℃

◆ Environment humidity:  30%～85%

◆ Barometric pressure: 700hPa～1060hPa

◆ In a clean, unlit room
