It adopts a flat-field semi-apochromatic design to eliminate field curvature and red-blue light aberration, ensuring that the entire field of view (25mm range) is clear without color fringing. The 12mm ultra-long working distance allows direct observation of thick samples (such as metal blocks, welded parts with protrusions) or reserves operating space for probes/clamps.

Application:
Inspection of metal surface defects, chip packaging textures, etc. The 45mm parfocal lens change avoids re-focusing, improving production line efficiency.
