This patent is a brand new type of Optical Encoder technology. Lencoders is an innovative and revolutionary optical encoder technology.  By using plastic lens-type code disc instead of gate-type glass one, it can increase several times of production speed, and lower costs with better yield rate and least components. Also, it can provide higher resolution and better quality than other optical encoders can.

    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.
