    Basic Info

    (1)Plano-Convex Lens
    Plano-convex lenses are used to collimate diverging light or to focus collimated light. We use them as secondary focusing lenses to refocus the collimated light sources.
    Plano-convex lenses have low spherical aberration. Use them with the plano side facing the point source or the focus and the curve side towards the collimated beam.
    In a Lens, the following parameter are usually used to declare it: diameter(Φ),central thickness(tc),radius(R),edge thickness(te),focal length(f),reflective index.
    Notes: Other sizes and coatings are available upon request!

    (2)Plano-Concave Lens
    Plano-Concave lens has a negative focal length,diverges collimated incident light, and forms only virtual images which are seen through the lens. It is often used to expand light beams or increase focal lengths in existing systems. The parameter follow the formulas as below:
    In a Lens, the following parameter are usually used to declare it: diameter(Φ),central thickness(tc),radius(R),edge thickness(te),focal length(f),reflective index.

    (3)Double-Convex Lens
    These lenses are primarily used for imaging at close to 1:1, illustrates their function. The convex surfaces of approximately equal to the radius of curvature. The lenses have very low optical aberration at magnifications from 5 to 0.2.At these magnifications, coma, distortion, and chromatic aberrations are minimal.
    Because both convex surfaces contribute to the magnifying power, these lenses are available with useful for collecting and refocusing light from a small beams in applications where the length of an optical train spot quality, you should use two lenses; one to collimate the diverging beam, and the second to focus the collimated beam to a small spot.

    (4)Double-concave lens
    Double-concave lenses are normally used in combination with other lenses. Typical applications include laser beam expanders, optical character readers, viewers, and projection systems.

    (5)Achromatic Lens
    Plano-conAn achromat is a lens consisting of two cemented elements made of diffrent materials, usually flint glass with crown glass. The achromat offers superior correction of spherical aberration in monochromatic applications.
    In addition to higher image quality, additional advantage of the cemented achromat include: simplified mounting since it becomes one unit, smaller light loss resulted from fewer surfaces, less stry light due to reduced reflections.

    (6)Meniscus Lens
    We call them Meniscus lenses because the two curves of the lens lies on the same direction, just like a meniscus when view by its cutaway view

    (7)Cylindrical Lens
    Cylindrical lenses are used in applications requiring magnification in one dimension only, such as in transforming a point image into a line image or changing the height of an image without changing its width or vice versa, therefore serving a variety applications, such as slit, line detector array illumination, bar code scaning, holography, optical information processing and computer, laser projection.

    (8)Ball Lens
    Ball lenses are glass spheres commonly used in fiber optics applications.Ideal for focusing light into fibers,(Figure 1)as well as fiber coupling (Figure 2). The ratio fo the collimated light input beam diameter to the ball lens diameter is defined as d/D (Figure 1). As the ratio increases, the back focal length increases.

    (9)Drum Lens
    Drum lenses are glass spheres, ground down axially to provide a mounting surface. The ground circumference D simplifies handling issues typically associated with ball lenses.

    (10)Micro Components-Cone Lens
    These components are designed for use in a variety of laser and imaging applications. The addition of this product line is part of a continued effort to support current trends toward miniaturization. Quantity pricing and custom sizes, including variations in polished/ground surfaces, are available to OEM customers upon request.
    Cone Lenses can be used for 360° illumination and imaging applications. Provided in coated and uncoated versions to allow special user-applied coatings if desired. Cone top and base are polished. Circumference is ground.
