The Tunable Light Source (TLS) family of products from Oriel® Instruments is tailor-made for users who want the flexibility of a modular design and the simplicity of an integrated system. All models are assembled, aligned, and fully characterized prior to shipment. The wide tuning range makes the TLS useful for a variety of applications. Finally, a pre-aligned and pre-assembled, versatile light source that requires no set-up!
The TLS is capable of outputting white light or monochromatic light from 250-2400 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 250-1800 nm from each unit manufactured. 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.
The TLS system comes mounted as a single unit to a mounting plate. Optics are pre-aligned. All the necessary interconnection cables are included and all of the hardware is mounted securely to the TLS baseplate.
Each TLS unit sold to a customer is tested prior to shipping to confirm that the unit meets factory standards. The customer receives this test report with his/her TLS unit for future reference. The final test data included with each unit includes:
Spectral Output Irradiance from 250-1800 nm with both 280 µm and 600 µm slits installed
Beam Spot Size and Beam Divergence Angle measured with both 280 µm and 600 µm slits installed
Temporal Stability measured over 1 minute and 10 minute operating periods
Beam Uniformity measured with both 280 µm and 600 µm slits installed at 450, 550, and 650 nm output
Wavelength Accuracy measured with the TLS output set to 450, 500, 650, 750, 850, and 1064 nm
Four versions of the Tunable Light Source are available. The TLS model chosen should be based on which lamp type is required and which external control method is preferable. More details on the advantages of Xe arc lamps and the difference between RS232/GPIB (IEEE-488) and USB can be found below. Users interested in QTH Model Tunable Light Sources should go to QTH Lamp Tunable Light Sources .
The TLS-300XR and TLS-300XU Tunable Light Source models use the 6258 300 W Ozone Free Xe Arc Lamp. The spectrum of a xenon arc lamp is typically smooth throughout the ultravioletic and visible wavelength ranges, with sharp emission lines between 750-1000 nm. Their sun-like emission spectrum and high UV output intensity makes them a good choice for solar simulation. Compared to QTH lamps, Xenon arc lamps have higher monochromator throughput and a smaller divergence angle. Ultraviolet light below 242 nm produces toxic ozone. The Xe arc lamp used in our TLS is ozone free, making it suitable for applications that do not require wavelength emission below 260 nm. The 66160 socket adapter required to use the 6258 in the Research Lamp Housing of the TLS is included with the system.
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.
