Frequently Asked Questions

Lithography microlens arrays are optical components made up of many tiny lenses arranged in a regular grid. They are fabricated using photolithographic techniques, allowing high precision and uniformity in lens shape, size, and placement.

Lithography-based MLAs offer superior surface quality, tight dimensional tolerances, and better alignment precision. They are ideal for high-performance optics where uniformity and reproducibility are critical.

They homogenize or shape laser beams by splitting and overlapping light through individual lenslets, resulting in a uniform illumination profile at the output — essential for applications like laser projection and material processing.

In autostereoscopic 3D displays, MLAs direct different images to each eye without the need for glasses, enabling a glasses-free 3D viewing experience.

Yes. They focus incoming light onto the active area of image sensors (like CMOS or CCD), increasing light collection efficiency, reducing cross-talk, and improving image sharpness.

Typical materials include fused silica, polymers (e.g., SU-8), or glass substrates. The choice depends on wavelength requirements, thermal stability, and application.

Yes. With the right materials and design, lithographic MLAs can operate in UV, visible, or IR ranges. Fused silica MLAs, for instance, perform well in both UV and IR.
