Warranty: 3 months Customized support: OEM Place of Origin: Jilin, China Brand Name: YT Model Number: YTVR19 Use: Optical Structure: Plano-convex Shape: Spherical, ball Material: K9/fused silica Application: optical Parallelism: 2 arc seconds Centering: 30 arc min Surface Quality: 60/40 Irregularity: L/4 Clear Aperture: >92% Diameter: 1-150mm Length: 2.6/1.8mm Optical Dome： Optical dome is composed of two parallel optical surfaces. Among optics domes are unique because, unlike any other optical components,the key attribute of the dome is to have no optical effect. Domes help correct aberrations that occur when light travels thru water as opposed to air. Domes can deliver better results compared to flat ports, and also make it easier or possible to achieve the results that flat ports would not capture.
