Guidance Lights Lens

The optical Guidance Lights Lens consists of two parallel Spherical lenses surfaces. In a perfect dome, the convex radius is equal to the sum of the thickness of the dome and the concave radius. Sometimes it is necessary to deviate slightly from this rule. The dome Optical Lens can withstand wind and rain erosion, helping to correct aberrations that occur when light passes through water instead of air. Therefore, optical dome lenses are mostly used in underwater photography equipment to provide clear and distortion-free protection for camera objectives or other sensitive equipment.
