Bonding of Endoscopes
Dual curing Vitralit® adhesives are ideal for bonding lens stacks as well as attaching glass and rod lenses in endoscopes. High strength bonds are formed between glass and metal components that offer biocompatibility, good chemical resistance, and minimal shrinkage. Their high glass transition temperatures ensure operating stability and reliability. These adhesives are compatible with all common sterilization processes.
Panacol adhesives are suitable for bonding rod lenses in endoscopes as well as for potting light guides.
