Deuterium Sources are ideal for UV Spectroscopy applications; the lamps emit high intensity UV radiation with little VIS and IR. Our new Apex Deuterium Source makes operation of deuterium lamps extremely simple. The Apex system is a fully integrated package - the lamp, condenser and electronics are in a single enclosure. Simply mount the lamp, plug in the power cord, and turn on the source. You don't need to align the lamp nor adjust the power supply setting. The sources are shipped factory pre-set to run any of the deuterium lamps listed in table 1. The 70635 includes the lamp of your choice; please specify lamp when placing your order.

Why Apex?
Apex Systems are for researchers who simply want to turn on their source and begin work. If you do not need the flexibility of the Series Q Systems, these sources offer a more economical option. However, you do give up some flexibility with Apex. Because there is only an ON/OFF switch, you cannot adjust the current or voltage. And, you cannot operate these sources with the 68950 Light Intensity Controller (used for long term, stability-critical applications).
Principle of Operation
Fig. 1 shows the simple optical path of an Apex Deuterium Source. A fused silica aspheric lens collects the lamp's radiation and collimates it. The output is a highly collimated, 1.3 inch diameter (33 mm) beam. You can then re-focus the output with one of our focusing lens assemblies. If you are focusing into a fiber, use our Apex Fiber Illuminator.
F/2 Condenser
We chose an F/2 aspheric lens as the condensing element because it has negligible spherical aberration, high throughput, and produces superior collimation. The multiplication factor is a measured parameter that helps in computing the approximate total power of the collimated output in any wavelength band.
1.5 Inch Series Female Flange
The output flange of both Apex Sources is a 1.5 Inch Series female flange. You can couple any male flanged accessory of the same series size to the output.
Mounting
Apex Housings have four leveling feet for free standing use. The feet allow 0.5 inch (13 mm) height adjustment. For hard mounting to an optical table, remove the feet and use the appropriate mounting holes.
Safety Considerations
Deuterium Sources emit very high levels of UV radiation. Even short periods of exposure to UV radiation can cause burns to the skin and eyes. Always use Ultraviolet Safety Equipment like protective eyewear, or gloves, and protective clothing. Or, enclose the beam path.

*The lens multiplication factor is a measured parameter for the lens. It helps in computing the approximate total power of collimated output in any wavelength band. Use formulae and sample calculations to compute the approximate total power from your source.
Oriel® Lamp Housing is designed to operate in a typical laboratory environment (typically 68 to 76 degrees F, up to 45% relative humidity). Temperature and humidity outside of typical laboratory range can contribute to cooling and ignition faults. Inadequate cooling will cause the over temperature sensor to open, and ignition problems will result from high humidity. Contact Newport technical representative for more information if operating outside the suggested range.
