LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Substrate Material: UV Fused Silica
Mounted in Ø25.4 mm Mount
Microlens Arrays Available in Round and Square
Commonly Used in Shack-Hartmann Wavefront Sensors
Dual-Sided AR Coating

LBTEK microlens arrays consist of microlenses arranged in a two-dimensional grid on a UV-grade fused silica substrate, with both sides coated with an anti-reflection film. LBTEK microlenses are fabricated using photolithography technology, which ensures excellent consistency in the shape and position of each microlens. The microlens array spatially divides the wavefront of a light beam into numerous tiny segments, each of which is focused by the corresponding microlens onto the focal plane. Based on this characteristic, the combination of a microlens array and a CCD array can form a Shack-Hartmann wavefront sensor. LBTEK offers two types of microlens arrays: anti-reflection coated and chromium mask. The unit sizes available are 150 μm and 300 μm. The microlens arrays with a unit size of 150 μm feature circular sublenses, while those with a unit size of 300 μm also feature square sublenses. For other requirements, please contact LBTEK technical support.
