A microlens, as the name suggests, is an optical lens with a very small diameter, often less than 1 mm. With advancements in technology and the increasing demand for miniaturization and integration, the research and application of microlenses have become more widespread. They play a crucial role in optical systems, such as micro-cameras, fiber optic communications, micro-lasers, and optical storage devices.

Key Parameters:
Lens Diameter: Determines the size of the lens and the size of the light beam.
Focal Length: Controls where the light focuses.
Shape and Material Refractive Index: These influence the direction of light propagation and focusing efficiency.
Materials:
Microlenses are made from various optical materials, including:
Fused silica (UVFS)
NBK7 glass,
H-K9L glass,
Fused quartz,
Optical glass,
Sapphire glass,
Applications:
Microlenses have broad applications across various industries:
Optical Systems: Used to focus light, adjust its propagation direction, and improve image quality.
Fiber Optic Communication: Enhance transmission efficiency by coupling optical fibers with lasers.
Micro-Cameras and Optical Storage: Improve image resolution and storage density by focusing light.
Biomedical Field: Manufacture micro-endoscopes for minimally invasive surgery and diagnostics.
Optoelectronics: Build micro-lasers and photodetectors for use in optical communication and electronic devices.
Types of Microlenses:
Microlenses are classified by their shape and manufacturing materials, including:
Spherical microlenses
Aspherical microlenses
Binary microlenses
Multi-layer microlenses
Among these, spherical and aspherical microlenses are the most common, with their primary difference being the surface shape of the lens.
We can customize microlenses based on customer drawings. The shapes can be round, square, rectangular, triangular, or other special shapes. Coating can be applied according to specific requirements. Feel free to contact us for inquiries.
