Where to Buy Microlens Arrays

Microlens arrays are rigid arrangements of very tiny lenses, each with a diameter of less than 10 mm. They are precision polished to very high tolerances, so that they can be mounted into complex imaging systems. Specifications • Diameter: +0, -0.1mm • Surface accuracy: λ/2 @633nm or better • Thickness: ±0.2mm • Centration: ±0.04mm • Surface quality:20-10 • Bevel: 0.2mm typical • Material: SK2; BK7 and more

Using our Nanoscribe Quantum X align tool, we can 3D print optical and mechanical microstructures directly onto surfaces such as fiber cores or photonic integrated circuits (PICs). This high-precision additive manufacturing process for microstructures is based on two-photon polymerization (2PP), in combination with state-of-the-art alignment technology. It enables a feature size down to 100 nanometers, with optical grade surface quality free from slicing steps. This allows full control over the optical properties of the printed optics. Not only can lenses be designed to focus or collimate light, but they can even take on aspherical shapes in order to correct for optical aberrations.

Some example applications of our 3D microfabrication process are:

• Microlens arrays on PIC surfaces or edges
• Lensed fiber arrays
• Prisms or other freeform optical structures
• Microfluidic or micromechanical structures

PowerPhotonic design and manufacture standard and custom micro lens arrays in 1D and 2D arrays. All products are manufactured out of high-grade fused silica and capable of both high efficiency and high power handling. Lenses can be spheric, aspheric or freeform due to our unique manufacturing process.

Holographix designs and produces cost-effective, high quality custom microlens arrays (MLAs) to customer specifications. We manufacture a wide range of polymer-on-glass MLAs using our proprietary UV replication technology. Our master molds are produced using a variety of mastering techniques, allowing us to offer replicated MLAs with a wide selection of possible lens profiles, packing configurations, sizes, and tolerances. We offer replicas in a range of refractive indices that are solder reflow compatible. Our manufacturing process and equipment allow us to produce precisely aligned single and double-sided MLAs with accurate polymer thickness and flatness control. We also offer wafer-level processing for customers that require high volume scalability.

Shanghai Optics Inc custom micro-lenses are made from high index optical glass. They are precision polished to very high tolerances, so that they can be mounted into complex imaging systems.
