  • Athermal laser optics made of plastics
    Patent number: 11385435
    Abstract: The invention relates to an athermalized device for generating laser radiation that is focused in a focal point, comprising a lens and a plastic housing and a passive adjustment system for adjusting the object distance S1. The passive adjustment device has an effective coefficient of thermal expansion (I) ? V = s 1 f · [ ? L - 1 n - 1 · ( ? n ? ? · d ? ? ? dT + ? n ? T ) ] + ? 2 · ( 1 - s 1 f ) .

  • Measuring module for remission photometric analysis and method for the production thereof
    Patent number: 9534951
    Abstract: A measuring module for remission photometric analysis of one or a plurality of specimens is provided with the following features: a transmitter with a transmission channel for transmitting a measuring radiation to location of the specimen; a first focusing device for focusing the measuring radiation on the specimen; a receiver with a receiving channel to receive the radiation reflected by the specimen; a second focusing device made of plastic for focusing the measuring radiation reflected by the specimen onto the receiver, whereby the second focusing device further comprises a filter which is designed to filter a fluorescence radiation from the specimen excited by the measuring radiation.

  • Access control on dynamically instantiated portal applications
    Patent number: 8316420
    Abstract: The present invention relates to a method and system for controlling access rights to dynamically instantiated portal applications in a portal environment, wherein new instances of a portal application and respective access control information on resources used in the application are generated dynamically from an automated programmed mechanism, and wherein a user-application role mapping is demanded for the portal application by a respective runtime access control function implemented at the portal environment.
