Heat-resistant lens kit

Abstract

A heat-resistant lens kit configured within the pogo tower of the wafer tester is disclosed. The heat-resistant lens kit has two parallel lenses and a main body with a through hole. The main body and two parallel lenses enclose a vacuum room within the through hole.

1 . A testing apparatus of light-sensing element, comprising:
 a probe card associated with a probe head thereon, wherein there are a plurality of testing probes on the probe head;   a pogo tower connected with the probe card and having an opening;   a holder of probe card arranged between the pogo tower and the probe card and configured for connecting the pogo tower and the probe card into a piece;   a heat-resistant lens kit configured in an opening of the pogo tower, wherein the heat-resistant lens kit comprises a main body with a through hole and two parallel lenses, and a suction hole and an indicator associated on the main body and the two parallel lenses, and an enclosed room is formed between the main body and the two parallel lenses; and   a chuck for loading a device under test.   
     
     
         2 . The testing apparatus of light-sensing element according to  claim 1 , wherein the heat-resistant lens kit is fixed in the opening of the pogo tower with a fixing component. 
     
     
         3 . The testing apparatus of light-sensing element according to  claim 1 , wherein the heat-resistant lens kit is connected with the pogo tower with an O-ring. 
     
     
         4 . The testing apparatus of light-sensing element according to  claim 1 , wherein the enclosed room is in vacuum. 
     
     
         5 . The testing apparatus of light-sensing element according to  claim 1 , wherein the indicator is made of spring, elastic sheet, sponge or elastic element. 
     
     
         6 . The testing apparatus of light-sensing element according to  claim 1 , wherein the chuck provides an environment below the room temperature. 
     
     
         7 . The testing apparatus of light-sensing element according to  claim 1 , wherein the chuck provides an environment below negative 40 degree Celsius. 
     
     
         8 . The testing apparatus of light-sensing element according to  claim 1 , wherein the main body is made of heat-resistant material. 
     
     
         9 . A heat-resistant lens kit, comprising a main body with a through hole and two lenses configured on two corresponding ends of the through hole to form an enclosed room, the characteristic in: a suction hole and an indicator associated on the main body and the two lenses parallel. 
     
     
         10 . The heat-resistant lens kit according to  claim 9 , wherein the main body is made of heat-resistant material.
