What is Biconvex Lens?

Biconvex lens also known as double convex lens. A biconvex lens means that both surfaces of the lens are convex. Its focal length is positive and mainly for the function of focusing. It is commonly used in imaging relay system and object imaging at finite conjugate distance. The smaller the conjugate ratio is, the smaller the aberration will be. We can provide both coated and uncoated lenticular lenses

Applications of Biconvex lens/double convex lens:
Biconvex lens as a simple lens, it has a wide range of applications including, but not limited to, focusing and control of laser beams, medium-quality imaging, and other optical instruments.
Ideally, the conjugation ratio (the ratio of image to object distance) will be between 0.2 and 5, and when the image and object distances from the lens are equal (conjugation ratio of 1:1), distortion, chromatic aberration and spherical image difference is minimized. Plano-convex lenses may be preferred when more distant objects must be imaged.

Our manufacturing capability of optical elements can supply a large variety of spherical & aspheric lenses, single prisms, windows, mirrors, laser & infrared optical components, etc. We have hundreds of grinders & polishers, spectrophotometers, Taylor Hobson profilometers, Optorun coating chambers, and interferometers of Veeco and Zygo to process and inspect all the optical components and make sure all customer standards are perfectly met.
