ASA Color silicone optics are backed by the powerful combination of both our silicone and optics expertise.
Asahi Rubber has decades of experience in optical engineering with an in-house team.
Beyond our optics experience, Asahi Rubber has been a molder of a broad array of rubber types for half a century.
We mass produce silicone parts from both liquid and millable polymers, using both injection and compression techniques.
So not only do we understand the fine points of optics themselves, but we know how to produce them with quality and precision.
Asahi Rubber also boasts proprietary off-gas control processing which all but eliminates silicone's main material drawback.
An additional step after secondary vulcanization reduces residual D3-D20 volatile siloxanes by over 98%!
D3-D10 volatile siloxanes are reduced by over 96%!
Silicone unlocks new possibilities in optics design.
Extremely sharp edges with fine detail are impossible or at least prohibitive in plastics and glass.
Using silicone primary optics, premium car headlights now feature advanced systems to control the direction and intensity of the beam.
Speaking broadly, there are three general types of materials used in lenses—plastics, glasses, and silicones (rubber).
In many aspects of both performance and cost, silicone rubber represents the midrange of the three material types.
Durable material with minimal clouding/yellowing issues
Visible light transparency
across whole spectrum over 90%
Excellent IR transparency
(UV as well)
