Laserlab, Inc.

Linear and Rotary Optical Encoders

Laserlab manufactures optical encoder strips (codestrips) and wheels (codewheels)

Custom and Stock items

We manufacture both custom and stock-item encoder strips and wheels. Our stock parts include 300 LPI (Line Per Inch), 0.007" thick, 0.7" wide codestrips with prepunched mounting holes. These strips provide a resolution of 1,200 steps/inch in quadrature. Popular sizes include 19.5", 25.5", and 38.5" models. We stock these for immediate shipment.

Custom offerings can be designed and fabricated in a few days or weeks, depending on the material, size, and resolution.

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.
