Selection of high-quality base materials:
Adapted to the performance of micro-optics Crafted from high-quality optical materials including BK7, fused silica, gradient-index (GRIN) glass and polymer substrates, our Microlenses offer diverse performance characteristics. BK7 and fused silica variants provide excellent optical transmittance and thermal stability for high-precision applications. GRIN glass lenses achieve focusing through refractive index variation across the lens, eliminating the need for curved surfaces and enabling ultra-compact designs. Polymer substrates offer cost-effective solutions for high-volume applications such as CMOS sensor arrays, with lightweight and moldable properties. All materials are selected for their low dispersion, high homogeneity and compatibility with micro-fabrication processes, ensuring consistent performance across large lens arrays.
Advanced manufacturing processes:
Ensuring micro-precision Our Microlenses are manufactured using state-of-the-art micro-fabrication techniques including photolithography, reactive-ion etching (RIE), molding and wafer-level optics. Wafer-level manufacturing enables simultaneous production of thousands of microlenses on a single substrate, ensuring uniformity and cost-effectiveness for array applications. Photolithography and RIE deliver precise lens profiles (spherical, aspherical, Fresnel) with surface roughness <0.01μm, minimizing light scattering. For GRIN microlenses, ion exchange processes create precise refractive index gradients for aberration-free focusing. The manufacturing process includes strict inspection for lens height, curvature and optical performance, ensuring each microlens meets the stringent requirements of micro-optical systems.
Ultraopto’s Microlenses are designed to be versatile, catering to a wide range of applications across various industries. They are suitable for integration into CMOS imaging chips, smartphone cameras, and micro-sensors, enhancing their resolution and light sensitivity. These lenses are also ideal for use in medical devices, such as endoscopes and microscopes, as well as in industrial inspection systems and augmented reality devices. Their compact size and excellent optical performance make them a perfect fit for any application that requires high-quality imaging at the micro-scale. Our Microlenses are widely applied in consumer electronics, medical devices, industrial sensors and scientific research.
In CMOS image sensors, they focus light onto photo-diode surfaces, improving fill-factor and low-light performance in smartphones, cameras and surveillance systems. In micro-imaging systems such as endoscopes and microscopes, they deliver high-magnification views in compact form factors. For fiber optic devices, they enable efficient light coupling between fibers and micro-components in communication systems. The lenses also find use in micro-optical arrays for spectrographs, biomedical sensors, augmented reality (AR) devices and laboratory micro-optical experiment platforms. Their versatility makes them indispensable in modern miniaturized technologies driving innovation across industries.
