Arc Light Source
Arc lamps are very strong sources of ultraviolet and visible light. They are excellent point sources of high brightness due to their small arcs. This feature makes arc sources a good choice when precise collimation is required. Arc light sources are also good choices for fiber optic applications, which require high intensity light focused on a very small point.

Sciencetech arc lamp systems are offered in two ranges:

  • arc lamps up to 200 W
  • arc lamps from 250 W to 1.5 kW

Sciencetech arc lamp systems allow the use of Xenon, Mercury and Mercury-Xenon arc lamps. The arc lamps can be operated in two types of housing, which differ in the condensing system :

  • wrap around ellipsoidal reflector
  • refractive condensers
