Upper Protective Window Cartridge

The Upper Protective Window Cartridge for Bochu BLT 3 and 4 Series Laser Cutting Head is a critical optical component designed to protect the cutting head’s internal lenses from contamination, debris, and damage during laser cutting operations. It features integrated water cooling to maintain optimal temperature and prevent heat-induced damage. Equipped with real-time temperature and gas pressure monitoring sensors, the cartridge enhances operational safety by detecting potential lens contamination or insufficient gas flow and stopping the laser if necessary to avoid quality degradation. The design includes collision protection and built-in amplifiers for stable and precise capacitance sensing, ensuring consistent cutting performance and extended lens service life for laser powers up to 4 kW. This cartridge supports easy maintenance, reducing downtime and repair costs while maintaining high cutting quality.
