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.
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.
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.
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.
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。

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.

Rod lenses are widely used in laser technology, optical fiber communications, medical equipment, scientific research instruments and other fields. In laser technology, rod lenses can be used to adjust the propagation direction of laser beams; in fiber optic communications , rod lenses can be used for coupling and splitting of optical fibers; in medical devices and scientific research instruments, rod lenses can be used for optical imaging and Spectral analysis, etc.
Window are of high precision dimension control, minimal transmitted beam deviation, high surface quality. With those excellent features, the BK7 ,Sapphire,Infrared etc window is widely use in projection optics systems, imaging and optical measurement system.
A rectangular optical window is a type of window sheet. Used as a protective window for electronic sensors or external environment detectors to separate the environment on both sides and protect internal components. The rectangular window slice does not change the magnification of the system, but mainly affects the optical path.
