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.
