Measuring angle, straightness, flatness, squareness & parallelism

The Autocollimator range For measuring angle, straightness, flatness, squareness and parallelism Used extensively in workshop, tool rooms, inspection departments and quality control laboratories throughout the world. Taylor Hobson Autocollimators – developments of the renowned Hilger and Watts products – are sensitive optical instruments designed for the accurate measurement of small angular displacements. There are a number of models in this comprehensive range, from the simple Minidekkor to the Ultra High Precision Autocollimator. The principles of autocollimation Light from an origin...

Autocollimation in practice Checking, measuring, indexing & monitoring Taylor Hobson Autocollimators are used in conjunction with reflecting mirrors or surfaces for the accurate measurement of small angular deviations from a datum angle. The main advantages of Taylor Hobson autocollimators are: • igh accuracy & wide range angle measurement H • Easy to set up and operate • alibration traceable to international standards C • Choice of Visual or Electronic systems • Wide range of accessories and levels Ultra High Precision Autocollimator with reference index table used to calibrate a polygon...

Visual Autocollimators Flexible, affordable, easy-to-use and read The visual autocollimators are extremely accurate instruments with a wide variety of applications. They are normally supplied with the eyepiece positioned for straight through viewing, although the TA51 is available with the eyepiece positioned for right angle viewing if required. Measurements are made using a graticule in the eyepiece viewing system with or without micrometers. The Taylor Hobson VA900 and TA51 Autocollimators incorpaorate a micrometer in the eyepiece viewing system for the precise measurements of angular...

…checking the TB100 clinometer with the TA51 autocollimator VA900 Microptic Dual Axis Autocollimator (code 112-2208 / M112-5767) • Lightweight high accuracy instrument • Ideal for precise measurement of angle of components such as prisms and for checking straightness, flatness and angular indexing • Wide range using combination of graticule and micrometer The VA900 Microptic Autocollimator is a dual axis, lightweight, highly accurate instrument. It is ideally suited for the precise measurement of angles or components such as prisms, for checking straightness, flatness or angular indexing....

Ultra Series Digital Autocollimators Dual axis Using the latest CCD technology the Ultra Dual Axis Autocollimator is a highly versatile instrument offering high accuracy and stability over a range of applications. Simple set-up This wide range Autocollimator comes with a laser sighting aid for simple setup. Combine this with the clear visual display on the autocollimators tablet PC and set up is easy even over long distances or with small reflectors. Clear results The Ultra Autocollimator also includes as standard the Taylor Hobson dedicated Optical Analysis software which allows advanced...

Indexing tables in the lab Ultra Autocollimator is ideal for measurement of angular indexing heads and tables. It is also commonly used to determine the errors of a polygon when used with a calibrated indexing table. Ultra High Precision Autocollimator (code 142-204-01) Key features • • • • • • Ultra high 0.1 sec accuracy Range of 300 seconds Simultaneous dual axis measurement Laser sighting aid for easy set up Includes software and tablet PC as standard Ideal for high precision measurement and indexing of small angles • Suitable for calibration of polygons, rotary tables and encoders •...

Application: Two axis straightness, squareness, parallelism and twist measurement of machine tool slides Among the large number of applications possible with the Taylor Hobson Ultra Dual Axis Autocollimator, the most common is the simultaneous two axis straightness measurement of machine tool slideways. Typically a ten metre slide can be checked in approximately five minutes – a considerable reduction in the amount of time taken compared with more conventional methods. The supplied PC also has Taylor Hobson applications software pre-loaded at no extra cost, for computerised measurement of...

Application: Parallelism of twin rails The addition of a Talyvel ® electronic level (M112-4515) on an adjustable base (112-5592) with optical square (142-77) allows parallelism to be set and checked in 2 axes. This is a common application which can be solved by using an autocollimator together with an optical square and mirror. Firstly the autocollimator is positioned and set up with the optical square to measure the first rail. The autocollimator can be mounted on trivets, tripods or heavy duty stands and the reflector is moved along the first rail and a series of straightness measurements...

Accessories Straightness & flatness measurement 6 Standard glass reflector 50 mm (2 inch) A reflector is an integral part of any Autocollimator system. Successful autocollimation requires a reflector of adequate flatness, reflectivity and diameter; this reflector meets all of these requirements. Steel reflectors and unmounted versions can be supplied to special order. Also available with a double sided reflector (112-5467) or as a single sided adjustable reflector (112-5468). • Diameter: 50 mm (2.0 in) nominal • Faces Parallel to Within: 5 secs • Faces Flat to Within: 0.1 µm (3.8 µin) •...
