Optical Components-Optical Dome Introduction:

 

Optical domes are lenses with two concentric spherical surfaces. Sometimes they are referred to as bent plane parallel plates. Consequently it is usual to define parallelism between two surfaces as the maximum thickness variation between the two surfaces. In perfect domes, the convex radius equals the sum of the dome thickness and concave radius. Optical domes are used for underwater photography, as a part of a protective case. Also they are as a part of sun tracking used in solar collectors.

Optical Components-Optical Dome Advantages

 

-Primary advantages:

 

CLZ Precision Optics can produce optical domes made of quartz, optical glass, silicon, etc., whose diameter can be up to 124mm. The angle can be 180 degrees and dimensional tolerances are +/-20 microns. The optical domes are manufactured on a highly repeatable 4-axis spherical machining center. They exhibit less than 20 microns wall thickness variations.

 

-Why should I buy optical components from CLZ Optics?

1. In our inventory list, you can find optical domes with different specifications.

2. According to diverse drawings from different customers, we have already produced kinds of custom domes for various applications.

 

Optical Components-Optical Dome Applications
