Long working distance + flat-field semi-apochromatic: A working distance of 12mm allows direct observation of samples such as 25mm thick metal blocks. The flat-field design eliminates field curvature, ensuring the entire field of view (25mm range) is clear without color fringing. Bright-dark field switching: Bright field is used to observe the distribution of metal grains, while dark field captures nanoscale scratches on the surface. No need to change lenses, improving efficiency.
Applications:
Preliminary screening of surface defects on thick metal plates, macro texture inspection of chip packaging, online observation of samples with fixtures (long working distance reserves operating space).
