  • Patent number: 10611662
    Abstract: A method for the production of glass components, an apparatus for carrying out the method, and a glass component that is obtainable through the method are provided. The method is a drawing method wherein a forming zone of a preform is heated to a temperature that allows drawing of the glass. The method includes a forming zone of the preform that is very small. Thereby the width of the preform is decreased to a smaller extent than its thickness. The glass components that can be obtained by this method have very smooth surfaces.

    Abstract: An optical arrangement for a camera module with an image sensor is provided. The optical arrangement includes optical components having a transparent cover element; an infrared absorbing cut-off filter; and an optical lens. The optical components are arranged, along an incident optical beam path going through the optical components onto the image sensor, in a sequence through the transparent cover element, then the infrared absorbing cut-off filter, and then the optical lens.

  • Patent number: 9752756
    Abstract: 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.
