Diameter 40mm was been no mass production, so we only have a few CLZ-DOME-40 in the stock.
For CLZ-.DOME-.40, Radius of a convex surface 20mm, Radius of a concave surface 18mm, Thickness of wall 2mm, height 21mm,
Concentricity< 0.2mm, thickness irregularity (TIR) < 0.2mm, 1mm over the hemisphere.
This is a low cost dome lens.
The material of these dome were made of H-K9L from CDGM.
We can manufacturing other type glass and size dome lens according to customer designes, our best achieve: Concentricity< 0.02mm,
thickness irregularity (TIR) < 0.02mm.
