The TLS130B-300X is capable of outputting white light or monochromatic light from 300-1800 nm with resolution as great as 0.7 nm (slit size dependent). Photodetectors with NIST traceable calibration are used to measure the output power from 300-1650 nm from each unit manufactured. The TLS130B-250Q is capable of outputting light from 350-1800 nm with spectral output power measured from 350-1650nm. The results are part of the characterization report packaged with each system. These are ideal for researchers or other end users who need a versatile light source that is ready to use out of the box.

When the 6258 Xe arc lamp inside the TLS system has reached its end of lifetime and needs replacement, changing the lamp is as simple as removing the old lamp and inserting a new one. Due to small manufacturing differences between lamps, a minor alignment procedure is required when a new lamp is installed into the TLS. This simple installation and alignment procedure can be done in minutes, as demonstrated in the video above.

The TLS includes the latest, most advanced version of Oriel’s TracQ Basic Instrument Control and Data Acquisition software. Using the 1/8 m Cornerstone 130B Monochromator's USB or RS232 port, TracQ switches the filter wheel position to the correct order sorting filter and the monochromator to the proper grating and position based on the TLS output wavelength chosen by the operator. When used with a compatible Newport Power Meter and Detector, TracQ is a complete radiometry system control software, capable of displaying real time data acquisition. No prior knowledge of software programming is necessary to install or operate TracQ. Some of the scans made possible with the TLS by TracQ include:

• Time Interval
• Lamp Radiometry
• Optical Power
• Absorbance
• Transmittance

TracQ Basic is compatible with Windows 7 (32-bit or 64-bit) operating systems.

When wavelength scanning over a wide spectral band, it is important to use order sorting filters in order to prevent second order wavelength emission. This ensures true monochromatic light is output by the TLS and detected by the photodetector. The TLS incorporates a Motorized Filter Wheel. This filter wheel utilizes four 1.0 inch (25.4 mm) diameter order sorting filters to minimize second order wavelengths from entering the monochromator and being falsely detected as signal light by the photodetector.

The TLS system uses fixed slits which offer the highest repeatability and accuracy. We include 280 µm and 600 µm slits. Other slit sizes are available here. Choose the optional 50 µm 77219 slit for 0.7 nm resolution. Determining which slit width to use is based on the tradeoff between light throughput and the resolution required for measurement. A larger slit width allows for more light throughput. However, more light throughput results in poorer resolution. When choosing a slit width to operate the monochromator at, both the input and output ports must be set to the same slit width.

The TLS system includes a manual iris, adjustable from 2-36 mm diameter, in the light output path. This iris is a convenient method for preventing detector saturation. By reducing the size of the output aperture to reduce output light intensity, a neutral density filter and mechanical coupling are not necessary.

Arc lamps may emit dangerous levels of UV radiation depending on their source type. Ensure that only authorized personnel are in the vicinity of the source, and wearing the necessary safety equipment such as UV protective eyewear, clothing, and gloves. Lighted UV warning signs, posted outside laboratory doors where UV sources are operating, can prevent accidental exposure. Newport also recommends using an electronic shutter to block the beam when the source is not in use but remains turned on. Alternatively, the beam can be safely contained by using beam tubes or fiber optic cables to deliver the light to a sample. It is recommended to vent the ozone that is produced by some lamp models to the outside or use the 66087 Ozone Eater.
