Advanced Optical Measuring System
Principal of Absolute Linear Scale
The grating scale of absolute linear scale consists of two grating masks, they are Absolute Grating Mask and Incremental Grating Mask respectively. Functions of this two masks are as per follows :
Absolute Grating Mask have different mask pattern over the whole grating glass, it gives low resolution but unique position readings over the whole measurement travel.
Incremental Grating Mask is an identical repeatable mask patterns over the whole grating glass, it gives very stable and high quality electronic signal for signal interpolation to achieve very high accuracy and resolution position readings.
Absolute Coding
All absolute coding used in our Absolute Grating Mask are designed by Easson, it is 100% our in-house design and intellectual property, designed and developed for different requirements of applications.
Aging Test
Optical Linear Scale's reader head need to power on for 72 hours aging test before assemble, make sure all linear scale's quality is reliable.
