Overview: This document provides detailed information on Taylor Hobson's range of autocollimators and accessories, focusing on the VA900 and TA51 Microptic Dual Axis Autocollimators. These instruments are used for measuring angles, straightness, flatness, squareness, and parallelism in various components.

VA900 Microptic Dual Axis Autocollimator: The VA900 is a lightweight, high-accuracy instrument ideal for precise angle measurement of components like prisms and for checking straightness, flatness, and angular indexing. It uses a combination of a graticule and micrometer for dual-axis measurement and comes with a dark field graticule. It does not include mounting fixtures, so appropriate accessories must be selected based on the application.

TA51 Microptic Dual Axis Autocollimator: The TA51 offers high accuracy and a wide angle, making it suitable for checking machine slides for straightness and squareness, as well as the flatness of surface tables and angular indexing tables. It includes a light field graticule and a levelling base, and can be used with various accessories for enhanced flexibility.
