Lenses have many applications ranging from the simple collection of a laser beam to precise imaging and image transfer. Lenses are classified as singlets, doublets and cylindrical lenses. Spherical Singlets include Plano-Convex Lenses, Plano-Concave Lenses, Bi-Convex Lenses, Bi-Concave Lenses, Positive Meniscus and Negative Meniscus. Doublets include Negative Achromatic Doublets and Positive Achromatic Doublets. Cylindrical lenses include Positive Plano Convex and Negative Plano Convex cylinder lenses

In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed.

Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. Betensh Optics can provide the size from Φ1～Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to OEM customers upon request.

Optical windows are flat plates made of optically transparent material, designed to allow light into an optical instrument. They can also be used to protect a light source from an outside environment.

Aspheric lenses refer to optical lenses that do not have spherical surface shapes. Aspherical lenses will have varying curvatures unlike normal spherical lenses that always have consistent curves, this is aimed at controlling light paths in a better way. This configuration helps reduce optical aberrations hence resulting into clearer and sharper images. Any customer sourcing for high-quality aspheric lenses must make sure they select a reliable supplier who will not only offer top notch products but also provide technical support as well as customization options that would serve specific requirements.
