A benchmark for ultra-long working distance: the 34mm spacing enables observation of ultra-thick/irregular samples (e.g., 3D printed parts, transparent thick films), while achieving a 5μm resolution (twice that of the 1X model).

It can be applied to thickness inspection of new energy battery pole pieces (thick coatings) and non-destructive observation of samples with complex morphologies (e.g., surfaces of cast and forged parts).
