Abstract

The device comprises a chamber in which a UV radiation source and an enclosure are arranged, the enclosure comprising a bottom wall for mounting a specimen, a UV radiation filter facing the bottom wall and a plurality of sidewalls interconnecting the bottom wall and the UV radiation filter.

Claims

exact text as granted — not AI-modified
1 . A light or weathering device for testing a specimen, comprising a chamber, a UV radiation source sited in the chamber and an enclosure arranged in the chamber comprising an enclosure wall with a UV radiation filter and enclosing the specimen at least in part. 
   
   
       2 . The device as set forth in  claim 1 , wherein the enclosure comprises a bottom wall for mounting the specimen, a UV radiation filter facing the bottom wall and a plurality of sidewalls interconnecting the bottom wall and the UV radiation filter. 
   
   
       3 . The device as set forth in  claim 1 , wherein the UV radiation filter has the shape of a rectangular disk. 
   
   
       4 . The device as set forth in  claim 3 , wherein four sidewalls are provided, each of which connects the four side edges of the UV radiation filter to the bottom wall. 
   
   
       5 . The device as set forth in  claim 1 , wherein the UV radiation filter is an edge filter, the edge of which is formed by a transition located within a wavelength range between an absorbing and a transmitting condition of the UV radiation filter. 
   
   
       6 . The device as set forth in  claim 5 , wherein included in the wavelength range is the wavelength 320 nm. 
   
   
       7 . The device as set forth in  claim 1 , wherein formed in two facing sidewalls are ports for porting a gaseous medium. 
   
   
       8 . The device as set forth in  claim 7 , wherein arranged in the device is a fan. 
   
   
       9 . The device as set forth in  claim 1 , wherein at the side of the bottom wall facing away from the UV radiation filter or in the bottom wall itself there is included a means for cooling the specimen. 
   
   
       10 . The device as set forth in  claim 1 , wherein several specimens can be staged within an enclosure. 
   
   
       11 . The device as set forth in  claim 1 , wherein just one specimen only can be staged within an enclosure. 
   
   
       12 . The device as set forth in  claim 1 , wherein several enclosures can be arranged in the weathering chamber. 
   
   
       13 . The device as set forth in  claim 1 , wherein just one enclosure only can be staged within the weathering chamber. 
   
   
       14 . The device as set forth in  claim 1 , wherein the bottom wall is formed by a portion of an inner wall of the weathering chamber. 
   
   
       15 . The device as set forth in  claim 1 , wherein the enclosure is movable within the weathering chamber. 
   
   
       16 . The device as set forth in  claim 15 , wherein the enclosure can be made to orbit the UV radiation source. 
   
   
       17 . The device as set forth in  claim 15 , wherein the enclosure can be secured to a frame capable of being rotated within the weathering chamber. 
   
   
       18 . An enclosure for a device for light or weathering testing specimens, including a bottom wall for mounting a specimen to be weathered, an UV radiation filter facing the bottom wall, and a plurality of sidewalls interconnecting the bottom wall and the UV radiation filter. 
   
   
       19 . The enclosure as set forth in  claim 18 , wherein the UV radiation filter has the shape of a rectangular disk. 
   
   
       20 . The enclosure as set forth in  claim 19 , wherein four sidewalls are provided, each of which connects the four side edges of the UV radiation filter to the bottom wall. 
   
   
       21 . The enclosure as set forth in  claim 18 , wherein the UV radiation filter is an edge filter, the edge of which is formed by a transition located within a wavelength range between an absorbing and a transmitting condition of the UV radiation filter. 
   
   
       22 . The enclosure as set forth in  claim 21 , wherein included in the wavelength range is the wavelength 320 nm. 
   
   
       23 . The enclosure as set forth in  claim 18 , wherein formed in two facing sidewalls are ports for porting a gaseous medium.
