  • A plano-convex lens is a convergent lens having one convex and one flat surface. These lenses are intended for use in infinite conjugate (parallel light) applications or for basic imaging in non-critical applications. Plano-convex lenses are designed for infinite conjugate use or easy imaging in non-critical applications. They are positive focal length elements with a flat and spherical surface. A lens can be convex, concave, or flat depending on its surface.

    A convex lens has an outward bulge, whereas a concave lens has an inward bend. They are employed in non-critical applications for limitless conjugate (parallel light) utilisation or simple imaging. Their primary application is in focusing elements, although they can also be used for simple imaging techniques. Plano-Convex lenses are suited for photography's all-purpose infinite conjugate lens applications. Plano-convex lenses are ideal for focusing parallel light rays to a single point.

    These lenses' asymmetry reduces spherical aberration in applications where the object and image are at uneven distances. The N-BK7 lenses are ideal for most general-purpose visible and near-infrared applications. UV Fused Silica lenses are suited for ultraviolet (UV) or high-energy applications. When an object passes through the focal point, the image transforms into a virtual image and appears enlarged on the same side of the lens as the thing. These lenses are suitable for a wide range of applications, including industrial, robotics, pharmaceuticals, defence, and laser cutting.These lenses' asymmetry reduces spherical aberration in applications where the object and image are at uneven distances.

  • Double convex lenses have positive focal length and form both actual and virtual images, they have shorter focal lengths. Z-Optics offers a wide range of Double-Convex lenses to maximize performance..
  • Plano-Concave Lenses are spherical negative lenses with one concave surface and one smooth surface. These lenses bend parallel light rays to the opposite side of the lens and thus have a negative focal length. Such lenses can be used to diverge light or to increase an optical system's focal length.
  • A Double Concave Lenses is nothing more than a biconcave lens with concave surfaces on both sides. Double-Concave Lenses are designed for applications such as beam expansion, image reduction, and light projection. Additionally, these lenses are excellent for increasing the focal length of an optical system.
  • Meniscus lens is a lens that has two curved spherical surfaces, one convex and the other concave. Around the middle, the meniscus lens is thicker than at the sides. Thus, with a rising beam waist and spherical aberration, the lens has a smaller beam diameter. When a meniscus lens is paired with another lens it shortens the focal length and increases the system's numerical aperture. This decreases the distortion of the image and increases the resolution of the image.
  • An achromatic lens is a type of lens that is designed to reduce chromatic aberration, which is the tendency of a lens to produce different colors of light in focus at different points. This is accomplished by combining two or more glass elements with different refractive indices. The most common type of achromatic lens is the doublet, which is made up of two elements, one concave and one convex. Achromatic lenses are commonly used in photography, telescope, microscope, and other imaging systems. They are also used in eyeglasses, binoculars and other optical instruments.
    Achromatic lenses are designed to correct for chromatic aberrations by combining two or more glass elements with different refractive indices. The most common type of achromatic lens is a doublet, which consists of one concave element and one convex element. The concave element is made of a low-dispersion glass, while the convex element is made of a higher-dispersion glass. When light passes through these two elements, the different dispersion properties of the glasses cause the different colors of light to come into focus at different distances. This is known as chromatic aberration. By carefully designing the curvatures of the elements and the spacing between them, the lens designer can create a lens that brings all colors of light into focus at the same distance, effectively eliminating chromatic aberration. Achromatic lenses are used in a wide range of applications where sharp and accurate imaging is critical, such as in photography, telescope, microscope, and other imaging systems. They are also used in eyeglasses, binoculars, and other optical instruments. Achromatic lenses are also commonly used in scientific research, for example in telescopes for studying stars, in microscopes for studying cells, in imaging systems for studying materials, and in other areas where precise imaging is necessary. In addition to the doublet lens there are also other types of achromatic lenses available, such as the achromatic triplet lens and the apochromatic lens. These lenses are designed to correct for chromatic aberrations even more effectively than the doublet lens, by using additional elements or specialized glasses. They are generally more expensive than doublet lenses but can offer even better image quality.
  • AG glass Windows is used on-screen to reduce sunlight/light reflection. The surface is etched by chemical to specified gloss, roughness and haze. A finished window might need post-treatment such as silk-screen printing, 3M double sides adhesive, heat tempered, coating. Please contact us for more information, supports or free samples.
  • An Aspheric Lens is one whose surface profiles do not resemble those of a sphere or cylinder. In comparison to a basic lens, Aspherical Lens can reduce or eliminate spherical aberration and also other optical distortions such as astigmatism. Main Applications of Our Aspherical Lens: - Collimator or condenser of the light source. - Collimator of laser. - Coupling lens to focus laser into an optical fiber. - Imaging
