  • Factory supplied Dome Lens For Camera - Optical Sphere Dome Lens – DG

    Factory supplied Dome Lens For Camera - Optical Sphere Dome Lens – DG

    Dome windows are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure. This makes dome windows ideal for underwater environments and in applications such as camera dome ports and submersible windows. BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability. UV fused silica domes (...

    Cheapest Price China Infrared Laser Lens - fused silica /Sapphire glass lens for high precision laser optics – DG

    Optical Windows An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a negative (concave) element made out of flint glass such as...

    Big discounting Glass Domes - Optical prisms – DG

    Application  This application is utilized by refractometer and spectrographic components. Since this initial discovery, prisms have been used in “bending” light within a system, “folding” the system into a smaller space, changing the orientation (also known as handedness or parity) of an image, as well as combining or splitting optical beams with partial reflecting surfaces. These uses are common in applications with telescopes, binoculars, surveying equipment, and a h...

    100% Original Rod Lens - Optical Glass Bk7 K9 Cylindrical Rods Lens for Optical Equipment – DG

    Optical Windows A rod lens is a cylindrical lens which has the geometrical form of a cylinder and has a polished mantle, while the two flat end surfaces may be ground. It is analogous to a ball lens for focusing in both directions. Rod lenses can be used, for example, for collimating a divergent beam in one dimension (see Figure 1) or for focusing light to a line. There are also imaging applications. Note, however, that a rod lens exhibits substantial spherical aberrations when light pr...

    Factory Cheap Hot Optical Spherical Lens - double convex lens – DG

    Bi-Convex Lenses are the best choice where the object and image are at equal or near equal distance from the lens. When the object and image distance are equal (1:1 magnification), not only is spherical aberration minimized, but also coma, distortion, and chromatic aberration are identically canceled due to the symmetry. Bi-convex lenses function similarly to plano-convex lenses in that they have a positive focal length, and focus parallel rays of light to a point. Both surfaces are spherica...
