Collection: BOCHU BOCI Laser 2nd-Upper Protective Lens

BOCHU BOCI 2nd-upper protective lenses are grouped here for the second-upper protective-window position in compatible BLT fiber laser cutting heads. Confirm the exact dimensions, part number and stated variant limit on the product page. This installation position is distinct from the standard upper and lower protective-window positions. For the standard upper position, see Upper Protective Lens; for lower-window products, see Lower Protective Lens.

BOCHU BOCI 2nd-Upper Protective Lens Specification

BOCHU BOCI second-upper protective lenses protect the optical path at the second-upper window position in compatible BLT cutting heads. The listed option uses a D25.4 × 4 mm format with model- and power-specific BOCHU part numbers. The installation position is different from the standard upper and lower protective windows.

How to Confirm Compatibility

Check the existing lens diameter, thickness, second-upper installation position, power range and original part number before ordering. Similar 25.4 mm windows may be used in different positions. Send a photo of the packaging label or cutting-head model plate if the correct position or part number is uncertain.
