What source type do I need (arc or halogen)? Which condenser optics should I use (lens material,

F/number)? ,VDUHDUUHHFWRUQHFHVVDU\" Will I need accessories?

The answers to these questions, along with a thoroughunderstanding of the application, will determine the com-ponents needed to provide an effective solution for your

light source requirements.

A word on safetyArc Lamps:When using arc lamps, you must have a condenser orwindow installed because of possible lamp burst. Even

with low-powered sources, UV radiation and ozone are aconcern. The easiest solution to the ozone problem is touse an ozone-free arc lamp if you do not need outputbelow 260 nm. If that is not an option, vent the ozone. Takeappropriate UV safety precautions; enclose the beam orwear UV protective eyewear and gloves. Our lamp hous-ings include safety features to prevent lamp damage andaccidental exposure. A door interlock prohibits the op-eration of the lamp while the door is open. Overheatingof the lamp caused by a defect is avoided by a thermalinterlock which shuts down the power supply.

INTRODUCTION TO LIGHT SOURCES

Halogen Lamps:

Although small in comparison to arc lamps, tungsthalogen lamps still produce UV radiation. Especially

the high wattages, the UV radiation is hazardous. Aways wear protective eyewear. Tungsten halogen lamreach surface temperatures up to 900 C during opertion. The cooling period can last up to 15 minutes; onthen is it safe to touch the lamp.

Condensing opticsWe offer different types of condensing lens assemblieThey differ in:

Lens material and therefore usable spectral rang F/number and therefore beam quality and collectio FROOOLPDWLRQHIFLHQF\

All condensers are intended for collimated beams, bcan also be positioned for compensating focal lengchange due to dispersion and to produce a diverging converging beam. The glass condensers do not transmbelow 350 nm. If you need UV output, choose a quacondenser.

For best uniformity use a slightly diverging beam. Fbest quality images use the condenser as a collimatand a secondary focusing lens. In this case choosecondenser with high F/number.

Power supplyThe power supplies are reliable current sources for ourXe and Hg(Xe) lamps as well as reliable power sourcesfor the Hg lamps. DC Mercury lamps must be operatedunder power control while DC Xe and Hg(Xe) lamps areoperated under current control. Our power supplies areeasy to use. The Xe and Hg(Xe) power supplies have an

RXWSXWSUHDGMXVWVZLWFKWKDWZKHQGHSUHVVHGFDXVHVthe meter to display lamp current setting prior to lampignition. The Hg power supplies have a three-positionlamp select switch that sets the internal circuitry of thesupply to operate 200, 350, or 500 W Hg lamps.

CoolingProper cooling is essential for correct lamp operation.The bulb temperature of arc lamps should not exceed600 - 900 C, because at higher temperatures the bulbis not able to withstand the high gas pressure due to atemperature-related change of the quartz structure (re-crystallization).

Modular constructionThis housing was especially designed for arc lamps. Butit also operates other sources like:

Halogen lamps up to 150 W

Switching within the same lamp category requires only

a new lamp adapter to position the lamp in the center ofthe housing.

Switching from one category to another, for example fromarc lamps to halogen lamps, requires a simple change ofinterface to meet the different electrical requirements ofthe different lamp types. Halogen lamps need two volt-age connections. All interfaces include cables to con-nect to the appropriate power supplies.
