Trioptics GmbH has integrated an automatic centering and cementing station with its OptiAngle system for measuring optical centration errors. Centering and cementing of optics, either in transmission or reflection, is accurate to <1 µm. Each step of the process of inspection, alignment, cementing and curing is programmable. A stepper motor stage positions the cement dispenser, and lens rotation is coordinated with the dispensing time. Two mechanical positioning assemblies are available.
