Spot light source LC8


Hamamatsu spot light sources employ long life, high intensity mercury-xenon lamps and optical systems specifically designed to minimize light loss. Our UV spot light sources have gained a solid reputation for long life and high power and now fill a vital role in different fields, especially in FA (factory automation). UV spot light sources generate less heat and so are ideal for UV curing in bonding of micro components and optical components vulnerable to heat.
