100 W Quartz Tungsten Halogen Lamp

The APEX2-QTH uses the 6338 100 W QTH lamp as its illumination source. QTH lamps exhibit better output stability than arc lamps and do not produce strong UV light emission or toxic ozone. Their smooth spectral output curve make them useful for radiometric and photometric applications.

Easy Optical Coupling and Software Interface with Oriel Monochromators and Spectrographs

The output flange of the APEX2 is the standard Oriel 1.5 inch flange, making for easy mechanical coupling with several existing Oriel instruments. Along with its wide compatibility with existing Oriel software packages, the APEX2 can be used with the following instruments:

  • Cornerstone 130B Monochromator
  • Cornerstone 260 High Resolution Monochromator
  • MS260i High Resolution Imaging Spectrograph
  • MS257 Monochromator
  • MS257 Imaging Spectrograph

If TracQ Basic Data Acquisition and Spectroscopy Software is used, the APEX2 and monochromator/spectrograph can also be integrated with an Oriel detection instrument, such as the LIDA-SRS-KIT and compatible detector. This setup creates a complete measurement system with light source, light analysis device, and light measurement detector.

Fully Integrated, Plug and Play System

Upon receiving the APEX2-QTH, the unit is ready to use after a simple lamp drop-in installation of the lamp. The user does not have to spend time aligning the lamp or programming the power supply to output the proper voltage and current. Simply plug in the unit and it is ready for use.

Adjustable Lamp Intensity

If the full output intensity of the 100 W QTH lamp is not required, an external DC voltage supply can be connected to the rear of the APEX2-QTH. An input voltage range of 0-5 VDC can be input into the system, 0 VDC corresponds to the lamp being off and 5 VDC allows the lamp to operate at its maximum 100 W power.

Manual Shutter

A manual shutter is integrated into the APEX2 to allow the user to close off the light path, blocking any light output from the system. This allows the user to be protected from UV radiation when light output is not required, such as warming up the lamp while preparing a setup or making a minor change in setup, without frequent and unnecessary restarts of the lamp.

Integrated Six Position Filter Wheel

A filter wheel is integrated into the assembly of the APEX2. Up to six order-sorting or neutral density filters can added (1.0 in or 25.4 mm diameter, 0.2 in. or 6 mm thickness) and filters can be changed as fast as 1.7 s/filter. An LED display indicating the filter wheel's current position is located on the rear panel so user can observe this while not being in the path of the output light, preventing exposure to UV radiation. Aside from manual control via the push button on the system, the filter wheel position can be controlled externally using the following methods:

  • TracQ Basic- Oriel's Data Acquisition & Spectroscopy Software
  • Oriel's Mono Utility - software included with the Cornerstone™ series monochromators and MS260i spectrographs
  • Universal Filter Wheel Utility - LabVIEW™ based utility program included with the APEX2, allows for control of the filter wheel via USB 2.0.
  • 74009 and 77709 Hand Controllers for Oriel's Cornerstone series, MS260i, and MS257 monochromators and spectrographs
  • USB 2.0 - the included sample Command Set can be used as is or to develop a custom Command Set better suited to the user's needs
