Bi-Convex Lens Optical Lens

Bk7 Optical Lens for Lighting,Projection,Imaging,Display,Laser

Overview:

Lenses have many applications in range from the simple collection of the scanning of laser beams to precise imaging and image transferring. Lenses are classified as singlet, achromatic cylindrical, and aspherical lens according to the different applications. Selecting the proper lens for your application requires making a number of choices. Many considerations include: lens shape, conjugate ratio, f/number, transmission, wavefront distortion, scattered light, anti-reflection coating, and cost... Base these, material is also an important factor for you to choose products. In Rising EO, the material of BK7, Fused silica, CaF2 and MgF2 as standard. Other materials are available upon requirement.

Description:

Double Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCV Lenses are used in a range of industries or applications.

Double-Convex Lenses are most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object (conjugate ratio) distances is between 0.2 to 5mm.

A double-concave lens is compose of two concave surface, has a negative focal length and are best used to diverge a converging beam. Similar to a plano-concave lens, a bi-concave lens can diverge a collimated beam to a virtual focus like a beam expander.
