Who We Are

Precision optics,
made to order.

OptiSil builds custom silicone lenses, domes, and windows for engineers who can't spec a part off a shelf. Every job starts with your requirement — geometry, hardness, refractive index, coating, and environmental rating — not our catalogue.

±20µm
Standard dimensional tolerance
72hr
Typical prototype turnaround
1.41–1.55
Refractive index range
IP68
Sealing rating achievable
How We Work

No stock catalogue.
Just your spec.

We work directly with your engineering team to define the part, then mould, inspect, and ship — with full traceability from raw polymer to finished component. One prototype or a production run, the process is the same.

Work With Us

Got a part that doesn't exist yet?

Tell us the geometry, the environment, and the tolerance. We'll tell you if it's possible — and how fast.
