Product Description

 >> Product Description

This dispersive objective is an optical component specifically designed for spectral confocal

displacement/thickness measurement systems. It features a wide-band, high-dispersion optimized design and is

optimized for integration into industrial precision inspection equipment. The product features a large numerical

aperture, high energy concentration, and low residual spherical aberration, enabling the stable output of high-quality

on-axis confocal spots. It is widely used for micro-thickness, micro-displacement, and surface topography inspection

in fields such as semiconductors, precision manufacturing, and new materials.
