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.
