Spherical lenses are lenses with at least one curved surface. They converge or scatter light, change the path of light and affect the wavefront curvature of light.It is widely used in medical imaging, laser optics, security monitoring, automotive industry, military industry, aerospace and other high-tech fields.They are important optical elements to improve the signal coupling between optical fiber, transmitter and detector.Horse Optical Co., Ltd. produces high-precision spherical lenses in the plano convex, plano concave, double convex, double concave and meniscus.

Plano-convex lenses are commonly used in various optical systems for focusing and collimating light.
When it comes to customization, there are several aspects of plano-convex lenses that can be tailored to specific requirements:
1. Material: Plano-convex lenses can be made from different materials, such as glass or plastic, depending on the application. Each material has its own unique optical properties, including refractive index and transmission characteristics.
2. Size and Shape: The dimensions of the plano-convex lens can be customized to fit specific optical setups. This includes the diameter and thickness of the lens, as well as the curvature of the convex surface.
3. Focal Length: The focal length of the lens determines its ability to focus or collimate light. By adjusting the curvature of the convex surface, the focal length can be customized to meet specific requirements.
4. Coatings: Plano-convex lenses can be coated with various anti-reflective coatings to minimize unwanted reflections and improve transmission. Coatings can also be used to enhance specific wavelength ranges or provide other desired optical properties.
