    Optical domes are lenses with two concentric spherical surfaces. Sometimes they are being referred to as bent plan parallel plates. Consequently it is customary to define parallelism between two su...
    The Plano-Concave Lens have one flat surface and one concave surface. They have a negative focal length and are used to diverge incoming light, or to increase focal length in an existing optical sy...
    These are lenses with one flat surface and one convex surface. They have a positive focal length and are used to converge or focus incoming light. They are best for infinite conjugate systems. They...
    Bi-convex lenses have a positive focal length. When the object and image distance are equal 1:1 magnification , not only is spherical aberration minimized, but also coma, distortion, and chromatic...
    Bi-concave lenses have two inward curved surfaces. These lenses have a negative focal length. Bi-Concave lenses are the best choice where object and image are at absolute conjugate ratios closer to...
    Uncoated Sapphire windows are ideal for harsh conditions, including environments subject to high temperatures, high pressures, strong vacuum, or corrosive atmospheres. Sapphire has high compressive...
    Optical grade Silicon is normally specified with a resistivity of 10 to 40 Ohm-cm which is higher than most semiconductor applications. The usual Silicon material, unless otherwise specified is CZ,...

    Plano convex lens is widely used in optical display systems, projection optics systems, imaging optical systems, and laser measurement systems. This lens is almost the most super form for both coll...
    Plano concave lens has a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or telescope. Because the spherical aberration of the ...
    Biconcave lens, is used to divergent light. The double concave lens is best used when the input beam is converging. It is used in beam expanders, projection optics systems, optical viewers and opti...
    Cylindrical lens is used to correct astigmatism in the eye, and, in range finders, to produce astigmatism, stretching a point of light into a line.. They are available in either plano concave or pl...
    Bonding Achromatic Lens is an achromatic consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. The elements are chosen so as to cance...
    Meniscus Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while ...
