摘要： Multiple channel multiplexing/demultiplexing devices include an optically transparent optical block seated atop an optically transparent beam-directing member. The optical block includes a plurality of wavelength selective elements, a plurality of reflectors, and at least one imaging optical element. The beam-directing member includes a beam folding mirror and focusing lenses. When the devices are used as demultiplexers, a multi-channel beam is directed into the optical block and relayed in a zigzag pattern onto the wavelength selective elements, which separate selected wavelengths from the beam. The separated wavelengths propagate through the beam-directing member and are focused onto optical receptors.

摘要： Striped dichroic filter having a substantially transparent glass substrate with a surface and having first and second sets of spaced parallel stripes disposed on said surface at an angle with respect to each other and with each of said sets of stripes being capable of reflecting at least one different color and with the stripes being formed of a plurality of layers of high and low index dielectric materials. In the method for making a striped dichroic filter, first and second sets of spaced parallel stripes are sequentially formed by sequentially depositing dielectric coating materials on sequentially formed stripe material which is subsequently etched away to remove the undesired portions of the coating material so that there remains first and second sets of spaced parallel stripes at angles with respect to each other and with each being capable of reflecting at least one different color.

摘要： Coating apparatus having a chamber with means mounted in the chamber for carrying a plurality of substrates to be coated. First and second sources are disposed in the chamber and contain coating materials which can be evaporated to produce vapor streams. Masking means is disposed between the first and second sources and the substrates for controlling the amount of each of the coating materials deposited by the vapor stream upon the substrates. The masking means includes a pair of masks and means for moving the pair of masks in accordance with a preprogrammed function so that a coating is deposited on the substrates which is comprised of a mixture of the coating materials having proportions related to the preprogrammed function. The means for moving the pair of masks includes first and second coaxially aligned shafts secured to the masks, a pair of drive motors, gearing connecting the drive motors to said shafts, and means for operating the motors in accordance with said preprogrammed function. The means for operating the motors includes control means for one of the motors comprising a reference following said preprogrammed function, means for sensing the position of the shaft of said one drive motor and means for comparing the reference signal with the position of the shaft to provide an error signal and means for driving said one motor until the error signal is reduced to zero.

摘要： Method for manufacture of a rotatable variable filter by controlling the deposition of a coating material on a substrate by the use of first and second masks in which the first and second masks and the substrate form three elements and in which at least two of the elements are rotated with respect to each other and the third element to cause the material to be deposited upon the substrate so that the optical thickness of the coating material varies with angle through a predetermined angle on the substrate.
