Focus electronic autocollimator with focusing objective tube

The TriAngle Focus electronic autocollimator series is based on the standard TriAngle design but employs focusing objective tubes for the measurement of slightly spherical mirror surfaces or some other systems with optical power. TriAngle Focus is ideally suited for the contact-free optical radius measurements.
