It also ascertained that a non-collimated light source, typically used in conventional solar simulators for flat modules, had a non-uniformity boost of between 2% and 20%, depending on the module.

The emergence of convenient sources of broadband light spanning ... Lasers are useful because they produce powerful beams of collimated, coherent light. The fact that laser light is monochromatic ...

Light is refracted within the lens, and depending on the geometry of the input source a lens can either focus or collimate light. If the input is a collimated light source, such as a laser, the ball ...

On-axis parabolic reflectors collect radiation from a source at its focal point ... Unlike standard parabolic mirrors, these mirrors direct and focus incident collimated light at a specific angle, ...
