MR device () comprising a miniaturized magnetic resonance system () and a cell culture chamber () for the analysis of biological samples of less than about 1000 μm in size, wherein said device () is at least partially covered by a passivation-binding layer (). The invention also concerns a method for manufacturing said device (), comprising a step of depositing a thin passivation-binding layer () on said system () The depositing step is preferably performed through a deposition process selected from chemical vapor deposition and physical vapor deposition.

Miniaturized MR device comprising a cell culture micro-chamber and method for manufacturing such a device

The present invention describes methods and apparatuses for creating superposition shape images by superposed base and revealing layers of lenslet gratings. The superposition shape images form a message recognizable by a human observer or by an image acquisition and computing device such as a smartphone. The superposition shape images may be created by different superposition techniques ranging from 1D moir&#xe9;, 2D moir&#xe9; and level-line moir&#xe9; superposition techniques to lenticular image and phase shift superposition techniques. Moir&#xe9; superposition techniques enable creating superposition shape images at different apparent depth levels. Applications comprise the protection of documents and valuable articles against counterfeits, the creation of eye-catching advertisements as well as the decoration of buildings and exhibitions.

The present invention relates to a reflective optical objective () comprising: &#x2014;a first reflecting element () including a front surface () and a hack surface (), the front surface () including a convex reflecting surface (); and &#x2014;a second reflecting element () including a concave reflecting surface () facing the convex reflecting surface () of the first reflecting element (), the second reflecting element () including a transmissive section () permitting electromagnetic radiation to pass through the concave reflecting surface () of the second reflecting element () to the first reflecting element (). The reflective optical objective () is characterized in that the reflective optical objective () includes a carrier material () embedding at least the front surface () of the first reflecting element () and defining the distance (d) between the first () and second () reflecting elements.
