Second-Lower Lens Cartridge Configurations
BOCHU BOCI second-lower protective lens cartridges support the second-lower protective window position in compatible BLT laser cutting heads. Each cartridge is designed around a particular head series, lens diameter, mechanical frame and original BOCHU part number.
How to Select a Second-Lower Cartridge
Confirm that the required position is second-lower rather than lower, then compare the cutting-head model, part number and lens dimensions. Position-specific cartridges may look similar but use different mounting details. Provide photos of the cartridge and head nameplate when the label is unavailable.
