Visual autocollimator
0.5 arc seconds | TA60, VA900, TA51 TAYLOR HOBSON

The TA51 has a wide range yet maintains a high measurement accuracy, this system is popular in the measurement and calibration of indexing heads and other angular devices such as polygons and clinometers. Combined with Taylor Hobson's alignment software (manual data input) this system can provide measurement features such as angle straightness, squareness and parallelism.
The system can be calibrated to traceable standards given the operator full confidence in results and maintaining high measurement integrity.

TA60 Visual Autocollimator
The TA60 is a cost effective dual axes graticule auto-collimator with a large gauge range to resolution. Its small size and robust design lend itself to fixturing making it easy to adapt to many different applications.
The wide field of view and dark field graticule (other options available) make it simple to use even on low reflective or small cross sectional surfaces making the system ideal for workshop and tool room environments.

VA900 Visual Autocollimator
The VA900 has an excellent range to resolution with an accuracy of 1 arc sec, this system is popular in the measurement and calibration of indexing heads and other angular devices such as prisms and clinometers. Combined with Taylor Hobson's alignment software (manual data input) this system can provide measurement features such as angle straightness, squareness and parallelism.
The system can be calibrated to traceable standards given the operator full confidence in results and maintaining high measurement integrity. The dual axis graticule and simple micrometer readout make this instrument popular with inspectors.
