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. Oplens can not only customize the common plano-convex lens of N-BK7 or fused quartz, but also customize the biconvex lens of any glass material. You are welcome to contact us for customized biconvex lenses.

An achromatic lens is a lens designed to minimize chromatic aberration and spherical aberration. Two-plate achromatic lens is one of the simplest achromatic lenses, which can be divided into two types: double agglutination and double dissociation. Of course, achromatic lenses can also be composed of multiple lenses, depending on their uses. The achromatic lens with large aperture is usually separated and assembled in the frame with excellent comprehensive performance. Achromatic lenses are widely used. A multi-lens optical system usually consists of several achromatic lenses. High quality microscopic objective lens and photographic lens are all complex lens combination systems which eliminate both achromatic and other monochromatic aberrations. Oplens can produce single layer or multi-layer anti-reflective films with all kinds of coating materials on both outside surfaces. Their performance is superior to that of all single element lenses.

The biconcave lens, also named double concave lens, is usually made of flint glass and used for beam divergence. It’s focal length is negative but the parallel incident ray diverges outward. The two sides of the biconcave lens curvature radius can be equal or not. Combined with plano-convex lens, it is generally used in beam expanders, projection optical systems and optical viewers, etc. Oplens can not only customize the common plano-concave lens of N-BK7 or fused quartz, but also customize the biconcave lens of any glass material. You are welcome to contact us for customized biconcave lenses.

A plano-concave lens is a lens that has a flat surface on one side and a concave surface on the other side. The focal length of a plane-concave lens is negative, allowing the beam to diverge.  Therefore, it can be used in optical system for beam expansion, light projection or to increase focal length.   Oplens can not only customize the plano-concave lens with common materials of N-BK7 (Shott) and fused silica, but also customize the plano-concave lens of any glass material.     You are welcome to contact us for customized plano-concave lenses.

Oplens Plano-convex lens is an optical lens in which one side of the lens is flat and the other side is convex. The focal length of plano-convex is positive, mainly for the role of focusing. The collimating beam can be gathered on the rear focus or the point light source can be transformed into a collimating beam. Plano-convex lenses are widely used in optical display system, optical projection system, optical imaging system and laser measurement system.   Oplens can not only customize the plano-convex lens with common materials of N- BK7 (Shott) and fused silica, but also customize the plano-convex lens of any glass material.     Parameters Material: Surface Flatness: Scratch/Dig: Eccentricity: Foca , l Length Tolerance Diameter Tolerance: Thickness Tolerance: Clear Aperture: Coating: Diameter Range: Optical Glass < λ/5 @ 633nm < 40/20 (both sides) ≤ 1arcmin < ± 1% < + 0.00/ - 0.02mm < ± 0.05 ≥ 95% of diameter AR OR BBAR  5~260mm Oplens is one of leading optical elements and spherical lens manufacturer.

Negative meniscus lens A meniscus lens is a lens with two spherical surfaces, convex on one side and concave on the other. The lens provides a smaller beam diameter to reduce beam waste and spherical aberration. When one meniscus is combined with another lens, the focal length is shortened and the numerical aperture of the system is increased. This reduces image distortion and improves image resolution. There are two types of meniscus lenses: ● Positive meniscus lens The positive meniscus lens is used for applications requiring small focal numbers (less than 2.5). For focal lengths between 2.5 and 10, a meniscus lens minimizes spot size and improves image quality. The concave side curvature of a positive lens is smaller and the convex side curvature is larger. Frequently used for beam focusing applications Minimizes the increase in spherical aberrations for multi-element systems ● Negative meniscus lens The negative meniscus lens is used for applications using infrared materials with a high refractive index. These lenses serve as substitutes for other negative lenses with greater curvature on the concave side and less curvature on the convex side. They are used in beam spreading applications where minimal spherical aberration is required. Frequently used for beam expanding applications Minimizes the increase in spherical aberrations for multi-element systems Parameters Material  Optical Glass Surface Flatness  < λ/5 @ 633nm Scratch/Dig  < 40/20 (both sides) Eccentricity  ≤ 1arcmin Focal Length Tolerance  < ± 1% Diameter Tolerance  < + 0.00/ - 0.02mm Thickness Tolerance  < ± 0.05 Clear Aperture  ≥ 95% of diameter Oplens provide custom optical components, we can custom sizes and shapes.
