Product Details
The center is thicker than the edge and has a converging effect on the light, so it is also called a converging lens. According to different shapes, convex lenses can be divided into biconvex lenses, plano-convex lenses and meniscus lenses, etc., by refracting light to change its propagation direction, so as to achieve the effect of image magnification, reduction, handstand or upright. The special shape leads to its unique optical properties. When the light passes through the cylindrical mirror, the light will be focused into a straight line or other forms of deformation. This property gives cylindrical lenses significant advantages in changing the size of the image, such as converting a point spot into a line spot, or changing the height of the image without changing the image width.

Category Product schematic diagram Technical index Transmittance / Reflectance Curve Plano-Convex Lens 
Surface finish: 40-20
Surface aperture: N-3; △ N-0.5
@633nm
Coating: R<0.25%Right-angle prisms can be used as 90° reflectors due to total internal reflection (TIR). When light enters from one of the right-angle faces of the prism, the light will undergo total internal reflection at the glass/air interface of the hypotenuse and exit from the other right-angle face. Right-angle prisms can deflect incident light by 90°, so they are very suitable for replacing reflectors.
Plano-Concave Lens
Surface finish: 40-20
Surface aperture: N-3; △ N-0.5
@633nm
Coating: R<0.25%A plano-concave lens has one flat side and one concave side, with the middle part thinner than the edges. It has a negative focal length and is used to diverge a beam of parallel light. It can convert a beam of parallel light into diverging rays, which will focus in reverse at the virtual focal point of the lens. It is used for applications such as beam collimation, increasing (decreasing) focal length, or enlarging (reducing) images. Bi-Convex Lens 
Surface finish: 40-20
Surface aperture: N-3; △ N-0.5
@633nm
Coating: R<0.25%A biconvex lens is a lens with both sides convex. The focal length in the middle of the lens is longer, which can converge light rays and focus them to a point. It has a positive focal length and is used to converge light from a point source or transmit images to other optical systems. Bi-Concave Lens 
Surface finish: 40-20
Surface aperture: N-3; △ N-0.5
@633nm
Coating: R<0.25%A biconcave lens has two concave sides, thin in the middle and thick at the edges, and is used to increase the divergence of converging light. The focal length is negative, causing parallel incident light to diverge outward. The two sides have equal radii of curvature and are used for beam expansion and projection. Meniscus Lens Surface finish: 40-20
Surface aperture: N-3; △ N-0.5
@633nm
Coating: R<0.25%A meniscus lens has one convex side and one concave side. It can be a converging lens or a diverging lens, determined by the refractive index, curvature, and radius. Achromatic Lens Surface finish: 40-20
Surface aperture: N-3; △ N-0.5
@633nm
Coating: R<0.5%Made of a combination of two lenses of different materials, the purpose of an achromatic lens is to focus light of two different colors to the same point, or to correct chromatic aberration.
