Generatrix Measuring Instrument for Cylindrical Lenses









Measurement of Centering and Parallelism Errors for Cylindrical Lenses
This instrument can measure the distance from the generatrix to the lens edges(a centering error). It can also measure the tilt angle of the generatrix (a parallelism error).
Easy Operation and Measurement
The operator can easily view the measurement results.
All you need to do is set the lens on the arm, slide the arm, and press the measurement button. A linear guide is used to move the arm, allowing the operator to easily operate the instrument.
Display of the Polishing Direction and Quantity
This instrument displays information that specifies which edge should be polished and how much should be scraped off in order to achieve the desired lens precision.*1
Adaptability to Various Lens Sizes
With the standard stage, this instrument can measure lenses to a maximum size of 60 × 40 mm. The operator can easily change the lens size by using the movable jaws and movable stage. 

*1: To obtain the measurement results, the lens date must first be registered.
