A micro lens array is simply a large number of very small lenses (lenses can be as small as 25 um) combined together in a single optic.
Nalux has decades of experience making microlens arrays and Nalux's customers can expect a great deal of design support and important advice during the design stage.
Optical system for optical communications, Head Up Display, Observatory telescope(Subaru Telescope) and illumination lamps etc.
Nalux specializes in microlens arrays for optical connectors for Active Optical Cables(AOC) used in large data processing systems.
Low insertion loss and tight control of the decay rate control. This is achieved by adjusting lens transmissivity by choosing the correct lens materials and by advanced evaporation coating design.
Typical tolerances include an array pitch of ±1um, location accuracy ±5μm by its standard and surface accuracy Peak-to-Valley tolerances of 1um or less are available for lens curvature.
We currently provide optical connector microlens arrays with between 22 and 16 channels which corresponds to SFP+・QSFP of VCSEL or Silicon photonics optical systems.
