IDS Imaging Development Systems GmbH, Adjust with light


Straightness and alignment are essential for trouble-free plant operation, especially with large machine components and rail constructions. Even small discrepancies can lead to increased signs of wear and paralyse a complete system. A precise alignment or measurement of e.g. linear guides is therefore decisive for the quality and service life of a system. With the ELWI-GER 3000, HOFBAUER OPTIK Mess- & Prüftechnik from Munich provides the machine and special machine manufacturers with the right instrument. The optical alignment and measuring system works precisely and quickly with the help of uEye industrial cameras and is suitable for long lengths up to 100 m.

Electronic autocollimators use the absolute straightness of light for non-contact high-precision measurements. The smallest straightness deviations of a surface or a guide can be detected by angle changes. For this purpose, a collimated light beam, i.e. a light package with parallel individual beams, leaves an optical system and is reflected back into it by a plane mirror. The ELWI-GER 3000 electronic autocollimator from HOFBAUER OPTIK thus enables 2-dimensional precise and rapid measurement of straightness and flatness. The flexible system can be used on technical surfaces for alignment and control of linear guides as well as for curvature measurement on large components and rail systems. This makes it just as suitable for plant construction as for track and tunnel construction. It can also be used for tasks such as testing stone rulers as straightness standards. For example, a granite ruler with a length of 160 cm can be measured in less than 5 minutes with an accuracy of < 0.5 µm/m. The optical testing device records the straightness in X and Y directions simultaneously and enables use in any position (spatial axis). The system includes the measuring head as well as extensive accessories such as an adjustable holder, a measuring mirror, an attachment laser as well as the corresponding USB connection to the display unit. Nevertheless, it is small and compact and works up to 8 hours in battery mode – ideal for service applications.
