Optical Glass Domes

Optical domes for Pyranometer in High Quality
At CLZ Precision Optics , we specialize in manufacturing glass optical Domes
from customer supplied designs. Capable of creating sizes from 10mm to 124mm in
Diameter. We are among the very few manufacturers in the world who possess this
technology.
Optical domes are lenses with two concentric spherical surfaces. Sometimes they
are being referred to as bent plan parallel plates. Consequently it is
customary to define parallelism between two surfaces as the maximum thickness
variation between the two surfaces. 
 In perfect domes the convex radius is equal to the sum of the dome thickness
and concave radius. Slight departures from that rule are sometimes desired.
Optical domes are used in IR missiles, for underwater photography as part of
protective case and as a part of sun tracking solar collectors.
The Pyranometer need protection of other electronic components and ability to
rely on withstand wind and rain erosion by optical domes.
