LBTEK Microlens Array consists of microlenses arranged in a two-dimensional grid on an ultraviolet fused silica (UVFS) substrate, with anti-reflection (AR) coating applied on both surfaces. The microlenses are fabricated using photolithography, which ensures high consistency in the shape and position of each individual lens. The microlens array spatially divides the wavefront of an incident beam into numerous sub-apertures, each of which is focused by the corresponding microlens onto the focal plane. If the incident wavefront is an ideal plane wave, a regular array of focal spots will be formed at the focal plane. However, in practice, most wavefronts are not ideal. When focused by the microlens array, the actual focal spots will deviate from their ideal positions. Based on this principle, a microlens array combined with a CCD array can form a Shack–Hartmann wavefront sensor. Additionally, microlens arrays are widely used in applications such as beam homogenization, beam shaping, optical fiber array coupling, solid-state laser pumping, and laser processing. LBTEK offers two types of microlens arrays: those with anti-reflection coatings and those with chromium masks. The models with anti-reflection coatings are MLAS10-F05-P150-AB and MLAS10-F15-P300-AB, while the model with a chromium mask is MLAS10-F04-P150-AB.
