For the creation of the first sub-assemblies, optical bonding is essential. This allows light to be propagated from one optical component to another, minimizing the energy losses caused by the passage between the various propagation means. The single optics are integrated on mechanical components, and for this the bonds are necessary in order to guarantee the necessary mechanical resistance to the various precision optical systems.

Our plant boasts a department dedicated entirely to optical bonding (glass-glass), and another for optomechanical integration for glass-metal bonding. Both departments have laminar flow hoods with blowers (up to ISO 5 class) and aspirants and UV ovens. Laser centers control the alignment of the axes of the individual elements, with precision up to 10 ''.

The bonding processes of Gestione SILO have successfully passed the durability tests imposed by some of our customers according to ASTM D 1002 standard. Below are the most used among the bonds we use for the most disparate applications related to optical systems precision:

Bonding with Norland

Being UV adhesives, they stop the optics in the desired position in a very short time. Norland 61, due to its chemical composition, is particularly suitable for making microscopes or, more generally, laboratory instruments.

Bonding with Lens Bond

These carry out very high precision couplings. Particularly suitable for prototyping.

Gluing with Rhodorsil

This produces assemblies with good thermo-mechanical resistance, also for precision couplings between very different materials.

Bonding with Mil Bond

This is the most commonly used adhesive for glass-metal couplings (both aluminum and steel). It is mainly used to make precision instruments for military applications.

Bonding with Caf

This type of adhesive is used mainly in the field of optomechanical integration both for sealing and as a real glue.

Silicate bonding

Our operators have been trained to carry out this type of bonding. The typical application is for vacuum chambers and laboratory prototypes.
