Linear and Rotary Optical Encoders


Laserlab manufactures custom optical encoder strips (codestrips)
and wheels (codewheels) to your specifications
Linear codestrips
Linear codestrips are also called encoder scales. These strips are ideal for low-cost
linear feedback applications where accurate position feedback is needed. A linear encoder
provides direct position feedback and eliminates the position errors that occur when using
a rotary encoder linked to a motor with leadscrew.
Rotary codewheels
Rotary codewheels are also called encoder discs or disks. They provide a low-cost way to
get feedback in rotary or linear applications when used in conjunction with a lead screw.
They are more compact and easier to mount than linear codestrips but only provide indirect
feedback in linear applications.
