YKK

High brightness halogen light source

　　　　　

【Introduction】

This is a light source unit for macroscopic observation lighting used in the flaw detection of the mirror-finished surface,the final and most difficult process in the processing of Si,GaAs wafers.

【Features】

1. Defects which are distinguishable only by veteran class inspectors can be easily observed by lighting of over 400,000luxes(when the irradiation area is 30mm in diameter).
   
   
2. Since a halogen lamp is use as the light source,the color temperature is high,3400°K,and the irregularities of illumination and color are small so that stable and sharp lighting is always secured.
   
   
3. The use of a cold mirror reduces the influence of heat from 1/2 to 1/3 that in case of the conventional aluminium mirror.
   
   
4. The beam diameter is continuously variable from 30 to 50mm by lens adjustment.
   
   
5. The foot switch permits easy tow steps change over of high and low illumination observation.The quantity of light can be controlled by volume adjustment.
