Lens assembly and lens assembly array

Abstract

A first lens having a first bottom surface and a first top surface at opposite sides thereof; and a first supporter having a first supporting surface and a second supporting surface at opposite sides thereof, the first supporting surface being flat, the second supporting surface being in contact with the first bottom surface, the first supporter being made of transparent material, and a refraction index of the first supporter being different from a refraction index of the first lens. A lens assembly array and method of making the lens assembly array are also provided.

 a first lens having a first bottom surface and a first top surface at opposite sides thereof; and   a first supporter having a first supporting surface and a second supporting surface at opposite sides thereof, the first supporting surface being flat, the second supporting surface being in contact with the first bottom surface, the first supporter being made of transparent material, and a refraction index of the first supporter being different from a refraction index of the first lens.   
     
     
         2 . The lens assembly according to  claim 1 , wherein the first lens and the first supporter are coaxially arranged, and a maximum diameter of the first lens is equal to a diameter of the first supporter. 
     
     
         3 . The lens assembly according to  claim 1 , wherein a refraction index of the first lens is in the range from 1.55 to 1.60, and a refraction index of the first supporter is in the range from 1.45 to 1.49. 
     
     
         4 . The lens assembly according to  claim 1 , wherein a refraction index of the first lens is in the range from 1.45 to 1.49, and a refraction index of the first supporter is in the range from 1.55 to 1.60. 
     
     
         5 . The lens assembly according to  claim 1 , further comprising a second supporter, the second supporter having a third supporting surface and a fourth supporting surface at opposite sides thereof, the third supporting surface being in contact with the first top surface, and the fourth supporting surface being flat. 
     
     
         6 . The lens assembly according to  claim 1 , further comprising a filter formed on the first supporting surface of the first supporter. 
     
     
         7 . The lens assembly according to  claim 1 , further comprising a second supporter and a second lens, the second supporter having a third supporting surface and a fourth supporting surface at opposite sides thereof, the second lens having a second bottom surface and a second top surface at opposite sides thereof, the third supporting surface being in contact with the first top surface, and the fourth supporting surface being in contact with the second bottom surface. 
     
     
         8 . The lens assembly according to  claim 7 , further comprising a third supporter, the third supporter having a fifth supporting surface and a six supporting surface at opposite sides thereof, the fifth supporting surface being in contact with the second top surface, and the six supporting surface being flat. 
     
     
         9 . A lens assembly array, comprising:
 a lens array having a first bottom surface and a first top surface at opposite sides thereof; and   a supporter array having a first supporting surface and a second supporting surface at opposite sides thereof, the first supporting surface being flat, the second supporting surface being in contact with the first bottom surface, a refraction index of the supporter array being different from a refraction index of the lens array.   
     
     
         10 . The lens assembly array according to  claim 9 , wherein the lens array comprises a plurality of lens portions, the supporter array comprises a plurality of supporter portions, and each lens portion is coaxially arranged with a corresponding supporter portion. 
     
     
         11 . The lens assembly array according to  claim 9 , wherein a refraction index of the lens array is in the range from 1.55 to 1.60, and a refraction index of the supporter array is in the range from 1.45 to 1.49. 
     
     
         12 . The lens assembly array according to  claim 9 , wherein a refraction index of the lens array is in the range from 1.45 to 1.49, and a refraction index of the supporter array is in the range from 1.55 to 1.60.
