Meaning
Liquid polymer that undergoes a permanent chemical reaction to form a rigid and transparent solid. Unlike thermoplastics, a thermoset optical resin cannot be remelted once it has cured. This material provides superior thermal stability and chemical resistance for high performance lenses.
Crosslinking Chemistry
Molecular bonds form a three dimensional network during the curing process. A thermoset optical resin offers higher scratch resistance than many common plastics. Production yields depend on the precise mixing of the resin and the catalyst.
Precision Casting
Viscosity remains low during the filling stage to allow the material to capture extremely fine details. Using a thermoset optical resin for micro-optics ensures that the shape remains stable even at high operating temperatures. Capability to mold thin sections without flow marks is a key advantage.
Thermal Durability
Finished parts resist deformation when exposed to soldering heat or intense light sources. The high glass transition temperature of a thermoset optical resin makes it suitable for automotive lighting. Calling a production run early before the full cure is reached leads to dimensional instability.
Demonstrating a rate of output requires a balance between cycle time and material properties. Long term exposure to high power lasers does not cause the material to soften.
