Application of spherical lens

The application of spherical lens mainly includes the following aspects:

Fiber coupling: Ball lenses are mainly used for coupling between optical fibers, between lasers and optical fibers, and between optical fibers and detectors, or for the collimation of optical fiber beams in membrane filter dense wavelength division multiplexers.
Light control: Spherical lens is used to focus, form images and collimate or expand light. The shape is divided into double convex lens, flat convex lens, double concave lens, flat concave lens, concave convex lens, cemented lens, etc. It is customized according to customer drawings or sample processing to meet different customer application requirements.
Endoscopes and barcode scanning: Ball lenses have a short back focal length that minimizes the distance required from the ball lens to the fiber and are typically used in endoscopy or barcode scanning applications.
Specific application scenarios include:

Chemical, military, aerospace, transportation, petroleum, light industry, medical and other fields: spherical lenses have the characteristics of good surface finish, good light reflectivity, high impact strength, chemical stability, and light bulk density. Used in these fields.
Lens technology is widely used in these fields, lens is the most basic optical element of microscope optical system, objective lens, eyepiece and condenser lens and other components are composed of single and multiple lenses.
Technical details:

Material: Traditional spherical lenses use optical glass materials. With the development of transparent polymer materials, especially the prevalence of LEDs, plastic aspheric lenses are currently used. Commonly used optical plastics are PMMA (polymethyl methacrylate), PC (polycarbonate), PS (polystyrene), etc.
Design and processing: The design and processing of spherical lenses requires high precision and expertise to ensure their optical performance. Different application scenarios require lenses of different shapes and sizes to meet specific light control and imaging needs.
