This Patent is derived from the patent of OPTICAL SCANNING LIGHT-GUIDING ENCODER BY FORWARD FOCUSING.  Like all Lencoders, it is manufactured by plastic lens-type code disc. It also owns the same advantages with all Lencoders’s Code Disc. Besides, It increases resolution by adding one or more layers of Lens Ring。

    Lencoders is the best encoder solution and leads others over 20 years at least.

    Optical encoder can be applied to many industries, such as automotive, industrial automation, CNC machines, Robots, and even the defense industry. Without optical encoders, Industrial 4.0 can not be presented.
