The photovoltaic device includes at least one solar cell and a concentrator optics, with the concentrator optics having at least one first, light-input-side, focusing optical element and at least one second optical element downstream of the first, light-input-side optical element and upstream of the solar cell, onto which, in operating position of the photovoltaic device, the bundled solar radiation falls by way of the first optical element, with the second optical element having a solarization-stabilized silicate glass. | 08-26-2010 |
20110254180 | Method for producing a rotationally symmetric lens from a ceramic green body and moulding tool for performing the method - The method for producing at least one rotationally symmetrical lens consisting of an opto-ceramic includes the step of moulding a ceramic green body for the lens, wherein the mould has a shaping surface, which is described by the following equation B: | 10-20-2011 |
20130265478 | CAMERA OBJECTIVE LENS WITH INFRARED FILTER AND CAMERA MODULE WITH CAMERA OBJECTIVE LENS - A lens system having an infrared filter for a compact camera module is provided. The lens system is an achromatic lens system and has two lenses. The first lens has a positive focal length, and the second lens has a negative focal length. The first lens is made of copper ion containing glass which absorbs infrared light and functions as an infrared filter. The second lens has an Abbe number that is smaller than that of the first lens with a difference between the Abbe numbers of the first lens and the second lens being at least 15. | 10-10-2013 |
20150138756 | LED LIGHTING DEVICE COMPATIBLE WITH NIGHT VISION DEVICES - A lighting device is provided that includes an LED and an NIR filter for a control panel or a display, which does not interfere with a night vision device. The light of the LED is in an area of u′>0.19 and v′>0.46 of the u′v′ diagram of the CIE-LUV chromaticity diagram. The NIR filter exhibits descending light transmittance between 500 nm and 800 nm. The thickness of the NIR filter is chosen so that a sufficient blocking effect is provided in a range of wavelengths between 600 nm and 800 nm, so that the color coordinates of the filtered useful light are in an area with a radius of 0.04 around coordinates u′=0.19 and v′=0.49 of the u′v′ diagram. | 05-21-2015 |
