Optical encoders white papers
Explore the latest optical encoders' white papers by Renishaw to gain in-depth insights into their advanced design, performance, and applications.
Tuned mass damping FORTiS™ encoders achieve class-leading vibration resistance
Machine tools produce significant vibration during operation, which can adversely affect the measurement accuracy of enclosed position encoders. Our white paper demonstrates that FORTiS encoders provide good positional stability and reliable operation, whilst being exposed to a wide range of vibration amplitudes.
The accuracy of rotary (angle) encoders
Rotary (angle) encoders are used in a huge variety of machines and devices. A rotary encoder consists of a position measurement readhead and an accurate rotary scale marked either on the periphery of a ring or on the face of a disc. This white paper outlines the major factors affecting rotary encoder performance to help designers choose the best encoder system for their chosen application.
Mounting encoder scales for optimum thermal performance
This white paper discusses the thermal performance of Renishaw's linear encoder scales. It includes options on how to calculate and compensate for thermally induced strains. It also explains how an expansion mismatch between the scale and the underlying machine substrate can impact on the overall performance of the encoder system.
Safety first - the position determination and checking algorithms of the RESOLUTE™ true-absolute optical encoder
Aside from providing excellent metrology in normal service, the design of RESOLUTE encoders is specifically optimised to assure dependable position output despite fault conditions or abnormal operation. This white paper gives an overview of the operation of the RESOLUTE absolute encoder and describes in detail the safety aspects of its position determination and checking algorithms.
Our optical encoders are available in a variety of configurations, including incremental or absolute, and can be linear, rotary, or designed for partial arc applications.
