Meniscus Lens
Processing Capacity
Capable to realize the complete processes in optical design, instrument design, component high-precision molding,
planar processing, spherical processing, aspheric processing, coating, etc.
Applications
Photoelectric information; aerospace; new energy; nuclear power and nuclear energy equipment and other fields.
Performance
● Meniscus lens is a crescent lens composed of two spherical surfaces with small curvature radiuses and little
numerical difference. Automatic achromatism is achieved when an appropriate thickness is selected. It can be
divided into anti-reflective multilayer film lens which is uncoated and coated with visible light band.
