Adopting a self-developed four-quadrant precision angle sensor architecture, adding a global sub-second high-order error compensation algorithm, combined with sub-pixel resolution photoelectric decoding and nano-level photolithography absolute encoding code disk, it brings stable and reliable one-second angle measurement Accuracy.
Using customized ultra-high-precision grinder precision processing technology, the carefully selected top-grade G3 steel balls are processed through dozens of processes to create a special-grade dense ball shaft system that can meet the stringent requirements of 1″ second total station.
