High Quality K9 Bk7 20mm Dome Lens1

A dome port is a concentric lens that adds an optical element to the camera lens. When the curvature of the dome's inside radius center is situated as close to the nodal point of the lens as possible, the dome port greatly decreases refraction, radial distortion, axial and chromatic aberrations.When using a dome port, all light rays pass through unrefracted, allowing the "in-air" lens to maintain its angle of view. A "virtual image" is formed optically just inches in front of the lens. When using a dome port to photograph a subject underwater, the lens must be focused on the "virtual picture," not the subject itself.

Dome lens have many applications. Customers with special needs may need to order customised dome lens to get the desired results. At DG Optics, we design and manufacture high-quality precision aspheric lenses according to unique specifications. Check out our options to build your own lenses, or request a quotation to learn how DG provides customised lenses, dome lens or other optical solutions at competitive prices.

We offer standard prisms and also high precision prisms with great angle accuracy in various shapes, configurations, substrates and custom coatings. Our standard prisms include Right-angle Prisms, Corner Cube Prisms, Wedge Prisms, Roof Prisms, Dove Prisms, Polygon Prisms, and more. Our custom anti-reflection and reflection coatings cover wavelength ranges including UV, UV-VIS, VIS, VIS-NIR, SWIR, MWIR, LWIR, and multiple laser line options. On our site you will also find Precision Prisms with arcsecond angle tolerance which are designed to meet the most demanding needs in systems that require critical alignments. This includes precision imaging displacement systems, projection systems, and beam combiner systems.

Many projects require custom optical lens, and for dome lenses, customization is the norm rather than the exception. After all, in order to achieve the desired results, a dome lens must match the exact dimension and specifications necessary to project a line of the proper length and focal distance.If you're looking for a manufacturer that can produce custom dome lenses to your exact specifications, DG Optics would make a strong choice. We have more than 25 years of experience designing, manufacturing and refining custom optical lenses for use in a range of industries. Our production staff follows strict ISO 9001 standards and uses state-of-the-art metrology equipment to test finished lenses for quality and performance .Choose from N-BK7 glass, UV fused silica, or CaF2 ,or other special materials specified by customers, all of which are available uncoated or with an antireflection coating with surface accuracy up to λ/8 and surface quality up to 10-5.To learn how DG could assist with your current optics project, request a quote online or contact one of our friendly representatives for more information.
