A562 3929 - TIR spot-focusing lens, dia 39mm

Lens A562 is our second smallest offered spot lens. Spot lenses are used in optical systems to reach a very narrow beam angle. Lens A562 is designed for small LEDs with dimension of a couple milimeters. The beam angle of A562 in a combination with Cree XP-G is 6,2°. You obtain a beam angle of 9° for lens A470 in a combination with Cree XM-L. The smaller light source is used the narrower angle is reached. If you require a beam angle below 6,2° you need to use bigger optics. We offer two more spot lenses and their size rises as follows: A559, A561. If you are looking for smaller spot lens in diameter you can inspect our A470. You can see comparison of simulation data for all our spot lenses and various LED sources in a file: Simulation results for spot lenses and various LEDs, which can be found under files for download. To reach the lowest value of the beam angle you need to use the biggest optics and the smalles light source.
