Lower Protective Lens Cartridge Options
BOCHU BOCI lower protective lens cartridges hold the lower protective window near the cutting process in compatible BLT laser cutting heads. Cartridge designs vary by head series, lens diameter, sealing structure and original BOCHU part number. The lower position is exposed to contamination and requires correct sealing.
How to Select the Correct Lower Cartridge
Match the lower installation position, cutting-head model, cartridge code and protective lens dimensions. Check whether the replacement includes only the cartridge or additional cover components. Send photos of the existing assembly, package label and head nameplate when the part number is not readable.
