UPT can manufacture encoder scales for optical linear encoders. If you are facing issues such as insufficient resolution, unmet delivery deadlines, or cost discrepancies with your current methods, please do not hesitate to contact us for a consultation.
What is Encoder Scale?
An encoder scale is a reference line (a physical line, film, or tape) used in conjunction with a linear encoder, and serves as a reference for the encoder to move. The linear encoder reads position changes on this scale.
Etching plays an important role in the manufacture of linear encoder scales. This process can precisely engrave minute patterns on metal substrates. Linear encoder scales are used in position detection systems to measure the movement of objects with high accuracy. Etching technology makes it possible to manufacture scales with extremely high resolution, which are used especially in the manufacturing processes of semiconductors and precision equipment.
