A dichroic optic having a first side and a second side, where the second side has an optical filter, where each of a light beam having a first wavelength, a second wavelength and a third wavelength enter, exit or reflect from the dichroic optic only from at least one of the first or second sides, where prior to incidence on the dichroic optic each of the light beams having the first, second and third wavelengths are non-collinear with each other, where the optical filter has a response capable of transmitting at least one of the light beam having the first wavelength and the light beam having the second wavelength, while reflecting the light beam having the third wavelength, and where the light beam having the first wavelength, the second wavelength, and the third wavelength are combined in a substantially collinear manner.

The present invention relates to a beam switch (1) for an optical imaging system. An at least partially reflecting foil (2), is sandwiched in a slanted position in a space between a first plate (3) and a second plate(4). The switch (1) further comprises a foil electrode (6) associated with said foil (2) and a first transparent electrode (5) associated with said first plate (3) and/or a second electrode (7) associated with said second plate (4). Application of a first voltage potential difference between said foil electrode (6) and at least one of said plate electrodes (5, 7) is arranged to attract said foil (2) towards a position essentially parallel with said first plate (3), in order to reflect light incident on said first plate (3) in a first direction. Application of a second voltage potential difference is arranged to allow said foil (2) to take said slanted position, reflecting light incident on said first plate (3) in a second direction.

Described is a device for selectively influencing the colour and direction of a white-light laser beam, in which the laser beam (W; W') is split into sub-beams (TR, TB, TG) of different colours and the intensity of each of the sub-beams controlled separately. The sub-beams are subsequently recombined to form a single beam (B) which is directed at a deflection device (14, 15). The device has electro-optical elements for independently controlling the intensity of each sub-beam.

A mems scanner package and a scanning projector including the same are disclosed. The MEMS scanner package includes a MEMS scanner including a mirror surface for reflecting light, a magnet disposed behind the MEMS scanner, a lower case having an accommodation space formed therein to accommodate the magnet, an upper case having an opening formed therein to pass light, reflected from the MEMS scanner, therethrough, and a transparent cover unit for covering the opening. The transparent cover unit is embodied as a transparent member, and is coupled to the upper case while being inclined at a predetermined inclination angle with respect to the MEMS scanner.
