TriLumina’s Illumination Modules provide a source of illumination for multiple applications, such as Driver/Occupant Recognition Systems, Industrial/Robotics, Gesture Recognition, Time of Flight Cameras, 3D-sensing and more.
Optimized for size, reliability and cost, the module generates invisible, infrared light using TriLumina’s patented VCSEL laser arrays. Through the use of integrated microlenses, it can produces a far-field divergence angle of less than 15 degrees. Similarly, with the integrated microlenses and/or the use of external optics, myriad FoV configurations can be achieved. Each individual VCSEL element’s beam combines incoherently in the far field to create a powerful, combined beam with little to no speckle noise.
Integrated microlenses can be used to maintain low beam divergence without costly and bulky external optics. Each VCSEL element is considered a point source, while the entire array acts as an extended source to enhance eye safety.
