Precision bonding for critical laser optics

Traditional mechanical connections reach their limits when assembling miniaturized laser components. Specialized high-tech adhesives offer an alternative joining method for various laser components due to the following advantages.

Advantages for alignment of optical components

• Ultra-fast curing: 1-5 second fixation for high-speed production achieving short cycle times
• Precision positioning: Micrometer-accurate component placement without tolerance stack-up
• Active alignment compatible: Perfect for precision optical alignment processes
• Thermal management: Excellent heat dissipation from laser diodes and components
• Vibration damping: Superior shock and vibration absorption for stable laser performance

Laser applications already enable new production processes today and have the potential to develop into a universal tool. With the epoxy adhesives of the DELO KATIOBOND family, DELO has now developed specialized adhesives that are excellently suited for laser system manufacturers. These dual-curing systems combine light and heat curing. Thanks to activation-on-the-flow technology, the adhesive can be pre-activated during application and subsequently cures within just one to five seconds. The adhesives demonstrate exceptional laser resistance, controllable shrinkage, and minimal outgassing – critical factors for micrometer-precise positioning in Active Alignment processes. Through ultra-fast curing, they can be processed quickly, which shortens cycle times in production. This reduces manufacturing times by up to 80 percent while maintaining the highest quality and makes laser technology more economical.

In addition to component bonding, DELO addresses the critical housing sealing of laser systems. While traditional O-rings and rubber seals can fail under extreme temperatures and aggressive environments, adhesive sealing offers significantly higher resistance. The DELO PHOTOBOND family delivers tailored solutions as liquid gaskets, suitable for both Cured in Place Gasket (CIPG) applications and Formed in Place Gasket (FIPG) processes. This liquid gasket optimally adapts to complex geometries of laser housings and ensures long-term sealing under extreme operating conditions.

DELO's innovative adhesive solutions enable laser system manufacturers to tap into new application fields from the automotive industry to medical technology, increase competitiveness through shorter production cycles, and ensure reliable systems with extended service life.
