  • Patent number: 11003086
    Abstract: An illumination optical unit for projection lithography illuminates an object field. The illumination optical unit has an optical rod with an entrance area and an exit area for illumination light. The optical rod is configured so that the illumination light is mixed and homogenized at lateral walls of the optical rod by multiple in-stances of total internal reflection. At least one correction area serves to correct a field dependence of an illumination angle distribution when illuminating the object field. The correction area is disposed in the region of the exit area of the optical rod. This can result in an illumination optical unit, in which an unwanted field dependence of a specified illumination angle distribution is reduced or entirely avoided, even in the case of illumination angle distributions with illumination angles deviating extremely from a normal incidence on the object field.

  • Patent number: 9513426
    Abstract: The disclosure provides a display backlight unit and its light down conversion film. The light down conversion film may include a quantum-dot layer sandwiched between input substrate and an exit substrate. First and second refractive asymmetric micro-prisms are disposed on two opposite input and first exit surfaces of the input substrate, respectively. On the input surface of the input substrate, multiple arrays of the asymmetric refractive asymmetric micro-prisms preserve the large off-axis angle of incident light with first wavelength. On the first exit surface of the input substrate, multiple arrays of the refractive asymmetric micro-prisms increase the reflectance of the large incident angle light. A second exit surface of the exit substrate includes refractive symmetric micro-prisms. The refractive asymmetric micro-prisms of the input substrate and the refractive asymmetric micro-prisms of the exit substrate have rounded tips and valleys for enhancing refraction of the first light and the second light.

  • Patent number: 9335770
    Abstract: Disclosed is an optical transceiver capable of controlling self-heating according to temperature, more particularly, an optical transceiver which uses a PTC heater suitable for temperature characteristics to easily control self-heating. A PTC heater of which the self-resistance changes depending on the ambient temperature of uncooled laser diodes of an optical transceiver so as to adjust heating volume of the heater, is applied to a TO CAN, thus making it possible to significantly reduce power consumption while expanding an available temperature range of existing optical modules, even without a separate controller or using a minimum number of control circuits.
