Applications
- Beam shaping and homogenization: Used in laser systems to create uniform illumination profiles.
- Image enhancement: Improves light collection efficiency and resolution in CCD and CMOS sensors.
- Light field imaging: Enables 3D image capture and refocusing in light field cameras (e.g., Lytro).
- 3D displays / autostereoscopic displays: Enables glasses-free 3D by directing different views to each eye.
- Spectroscopy: Improves light collection in spectrometers and hyperspectral imaging systems.
- Confocal microscopy: Focuses excitation or collection light into multiple points for faster scanning.
- Wavefront sensing: Arrays of microlenses focus light from different parts of a telescope’s aperture to analyze distortions.
- Adaptive optics: Paired with deformable mirrors to correct atmospheric distortion in telescopes.
- Wafer inspection systems: Ensures uniform illumination and high-resolution scanning in semiconductor manufacturing.
- Optical profilometry: Used to focus and analyze surface topography.
- VCSEL coupling: Aligns vertical-cavity surface-emitting lasers with fiber arrays.
- Free-space optical interconnects: Facilitates efficient light coupling and multiplexing.
- Lab-on-chip and bio-sensors: Directs and focuses excitation light or collected signals in miniaturized detection systems.
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.
