SCIENCETECH was
formed in 1985 to serve the optical instrumentation market specifically
in area of spectroscopic instrument design. They have designed hundreds
of instruments with application in medicine, materials research,
industrial processes, and space science.

| 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

- Model FB-MH-5 from Sciencetech
is an illuminator designed for fiber optic applications.
It has been specially designed for applications where
a high throughput of visible light is required in
a fiber.
