    摘要： An apparatus for wavelength multiplexing optical signals, wherein the apparatus includes at least one optically conductive sleeve, at least one collimating lens positioned to receive a optical signal from the at least one sleeve, and at least one dichroic splitter positioned to receive the optical signal from the at least one collimating lens. A filter may further be positioned to receive the optical signal from the at least one dichroic splitter in order to further filter the optical signal. The apparatus for wavelength multiplexing is configured to provide optical isolation of at least 75 dB via the combination of the at least one dichroic splitter and filter elements.

    摘要： An optical film, a polarizing plate and a display device are provided. The optical film can have desired phase retardation at a wide wavelength range, and also show no light leakage at an inclination angle. Also, the optical film can have ¼-wavelength phase retardation, and can be used for reflective or semi-transmissive/reflective liquid crystal display devices or organic light-emitting devices.
