| 20080239509 | Compact imaging lens assembly for an imaging-based bar code reader - An imaging lens assembly ( | 10-02-2008 |
| 20080297918 | SIDE EMITTING LENS, AND BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY INCLUDING THE SAME - The present invention provides a side emitting lens that may reduce optical loss and improve light emitting ratios, and a backlight unit and liquid crystal display including the side emitting lens. The side emitting lens may have a substantially dome-shaped body. The body includes a base part on which external light is incident, a refracting part to refract incident light and emit the light from side surfaces, and a reflecting part. The reflecting part is in the shape of a conical recess at a central portion of the refracting part to fully reflect the incident light toward one of the refracting part and the base part and the reflecting part comprises two or more reflecting surfaces. Each of the two or more reflecting surfaces is a curved surface. | 12-04-2008 |

| 20140118843 | OPTICAL ARRANGEMENT FOR CONVERTING AN INCIDENT LIGHT BEAM, METHOD FOR CONVERTING A LIGHT BEAM TO A LINE FOCUS, AND OPTICAL DEVICE THEREFOR - In a method for converting a light beam to a line focus, wherein the line focus extends according to its length along a first direction (y) and is narrow in a second direction (x) perpendicular to the first direction (y), the light beam is directed onto at least one conical optically operative surface, by which it is converted to the line focus. The light beam is directed onto the at least one optically operative surface with a ring-segment-shaped cross section transversely with respect to the light propagation direction. A device, in particular for carrying out the method, and an optical arrangement for generating a light beam with a ring-segment-shaped cross section are likewise described. In accordance with a further method and a further device, a line focus is generated only with spherical and/or cylindrical elements. | 05-01-2014 |
| 20140268368 | Optical device for beam shaping - The invention concerns an optical device and its application to generate an adjustable wave front deformation of a laser beam and thus to generate an adjustable beam spot geometry in the focal plane of laser optics. For this purpose, a device is provided which allows adjusting and modifying a laser beam in such a way that a beam spot, the shape of which can be adjusted continuously based on the original focal shape, is generated after focusing the beam, i.e. at least one dimension parameter of the shape of the beam spot has to be variable and adjustable so that the beam parameter product of the beam can also be modified without having to modify the focal position. | 09-18-2014 |
| 20140293442 | LENS MODULE - A lens module, including: a first lens including a first conical surface based on an optical axis and a first flat surface extending in a vertical direction with respect to the optical axis; and a second lens including a second conical surface based on an optical axis and a second flat surface extending in a vertical direction with respect to the optical axis, wherein the first conical surface and the first flat surface are connected by a first curved surface having a first radius, and the second conical surface and the second flat surface are connected by a second curved surface having a second radius. | 10-02-2014 |
