LC-1 Optical Lens Transmitted
Wavefront Measurement System
Features
This is a real-time measurement and evaluation system of transmitted wavefront through optical lenses applying a high-speed optical sensor.
- Since real-time measurements can save the inspection time, it can be used for 100% inspection in the production line.
- Convex and concave lenses can be evaluated by adopting the double pass method that uses spherical reference surfaces.
- Luminous flux diameter conversion unit allows evaluation of - various types of luminous flux diameter lenses.
Applications
- Wavefront evaluation of group lenses, set lenses and single lenses, which are generally used for digital cameras
- Evaluation of wavefront of aspherical lenses
- Evaluation of convex and concave lenses
