1 minute or 30 SecondPlano-convex lenses are perfect for systems with infinite conjugates, making them ideal for simple imaging setups. With a flat and a convex surface, they efficiently focus light, and their orientation is crucial for optimal performance—typically, the flat surface faces the focal plane. Their ability to minimize spherical aberrations enhances image clarity, a crucial aspect for high-precision tasks.

We specialize in manufacturing high-quality plano-convex lenses. These versatile optical lenses feature a positive focal length and are designed for various imaging and focusing needs. Plano-convex lenses are a fundamental choice in optical systems, offering significant advantages for applications requiring light collimation and monochromatic illumination.
Details
Betensh Optics manufactures a wide variety of plano concave lenses optimized for the UV (ultraviolet), visible, and IR (infrared) spectrums. Our range includes options with AR coatings for enhanced performance. We also offer custom optical lenses, including bi concave lenses and double concave lenses, ideal for applications requiring light divergence or image formation from distant objects.
Details
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. Betensh Optics offers Double Convex lenses with a variety of coating options.
Details
Double Concave Lenses are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths. Betensh Optics offers Double Concave lenses with a variety of coating options.
Details
An achromatic lens, often called an achromat, is a type of optical lens capable of correcting chromatic aberration, a distortion that occurs when glass splits white light into multiple colorwavelengths in the spectrum.

A cylindrical lens or cylinder lens is an optical lens with a cylindrical or semi-cylindrical shape。 The Plano Convex Cylindrical Lens Plano Concave Cylindrical Lenses Aspheric Cylindrical Lens
Details
Aberration Correction: Meniscus lenses are often used to correct aberrations in optical systems, thereby improving image quality. Condensers: In illumination systems, meniscus lenses can be used as condensers to focus light. Chromatic Aberration Elimination: By selecting the appropriate thickness, meniscus lenses can eliminate chromatic aberration, enhancing the optical performance of the lens.
Details
A ball lens consists of a highly transparent spherical ball, usually made of solid glass (fused silica) or another optical material with a refractive index of less than 2. Most ball lenses have small diameters — typically a few millimeters or even less than a millimeter. The optical physics can be understood by realizing that these lenses are, equivalently, two plano-convex lenses separated by a parallel plane.
