BOCHU BOCI Focus Cartridge Unit

Explore BOCHU BOCI focusing cartridge units for BLT laser cutting heads. The collection covers multiple BLT series, focal lengths and BOCHU part numbers. Review the focal length, cartridge type and matching cutting-head model on each product page before ordering.

Focusing Cartridge Units by BLT Series

BOCHU BOCI focusing cartridge units are available for different BLT cutting-head families, including BLT3/4/5 and BLT6 series configurations. Units can differ by focal length, optical arrangement, mechanical structure and original BOCHU part number. The correct unit must match the complete cutting-head configuration.

How to Select a Focusing Cartridge

Confirm the BLT series, focal-length specification, cartridge part number and installed optical position. Do not select a focusing unit only by housing shape. Keep the optical surfaces protected during handling and send the existing label and cutting-head nameplate when requesting compatibility confirmation.
