Abstract
An arrangement utilizes diffractive, reflective and/or refractive optical elements combined to intensify and homogenize electromagnetic energy, such as natural sunlight in the terrestrial environment, for purposes such as irradiating a target area with concentrated homogenized energy. A heat activated safety mechanism is also described.
Claims17
An arrangement for concentrating incident electromagnetic energy onto a target, the arrangement comprising:
- at least one optical member comprising:
- a refractive member or a reflective member;
- at least one diffractive member, the diffractive member comprising a plurality of diffractive elements, the diffractive elements constructed and arranged to diffract and homogenize incident electromagnetic energy, the diffractive member constructed and arranged to pass the diffracted and homogenized electromagnetic energy directly to the target, wherein the arrangement concentrates the electromagnetic energy into a highly eccentric ellipse.
