Lentils are small, lens-shaped seeds from the legume family and are widely consumed across the globe. There are various types of lentils, including brown, green, red, yellow, and black lentils. Each variety has its unique flavour, texture, and culinary uses. Lentils are a rich source of plant-based protein, fibre, vitamins (such as folate and B vitamins), minerals (including iron and potassium), and antioxidants.

Meniscus lenses have positive meniscus lenses and negative meniscus lenses, they are used in telescopes, camera, collimators, laser systems. Sunday offer coatings AR,Mgaf2 on broad wavelength.
Optical Cylindrical lens PARAMETER: Meniscus Cylindrical Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.

Cylindrical lenses are either plano-convex or plano-concave in form and rectangular in shape. These lenses are used in applications requiring magnification only, such as in transforming a point image into a line image or changing the height of an image without changing its width or vice versa. Therefore serves a variety application, such as slit line detector array illumination, bar code scanning, holography, optical information processing and computer, laser projection.

Plano-convex lens, aslo called positive lens, is used to converge incident light to a spot on the axis, at a certain distance behind the lens, which is knowed as focal length. It can form both real images and virtual images(for magnifier) on the two sides. The materials to make plano-convex lens can be BK7, Fused Cilica, sapphire and CaF2 etc., for different applications.This model are commonly applied in many devices including telescopes, collimators, magnifiers,optical transceivers, condensers and other optical display or imaging optical systems. AR/NIR or other coatings are available according to the applications.
