Advanced Optical Measuring System
The slide carrier of the GS series scales, use a five bearing design for optical grating linear transducer which has been proven
as the most reliable system design in today's market.
The glass grating slideways are lapped, and JIS standard P5 grade bearings are used to achieve smooth and accurate movement and
long working life.

Doubel Seals Design
The plastics seals of GS series scales use an innovative material to offer superior oil resistance, high elastic recovery properties and durability, carefully designed lips geometry offer low slide resistance.
100% Laser calibration
All glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring
accuracy comply 100% with the specifications.
accuracy comply 100% with the specifications.
ASIC for signal interpolation
ASIC for signal Interpolation is built-in inside the GS Series Glass grating linear transducer to facilitate increased resolution
of the grating. All frequency multiplication is implemented 100% by hardware phase shifting inside the ASIC to minimize the real time measurement error. Because all resistor ladders for phase shifting are constructed with the same piece of semiconductor inside the ASIC, which have same temperature coefficient, therefore. error drift caused by environmental temperature change is minimized.
