Features

Highest Output Intensity

The TLS260 series outputs a much greater light output intensity than its predecessors. Two versions of the TLS260 are available: The TLS260-300 X includes the 6258 300 W, ozone-free Xenon arc lamp. Xenon arc lamps useful for solar simulation applications due to their sun-like emission spectrum and high UV output intensity. They exhibit a typically smooth output curve throughout the ultraviolet and visible wavelength ranges, with sharp emission lines between 750-1000 nm. 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 Xenon 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. The TLS260-250Q includes the 6335 250 W Quartz Tungsten Halogen (QTH) lamp. QTH lamps are popular light sources for spectral sensitivity measurements due to their relatively smooth output curve in the visible to near-infrared wavelength ranges, with minimum ultraviolet emission. The 6335 is a specialized QTH lamp hand selected for use with the TLS260-250Q. QTH lamps have a typical operating lifetime on the order of tens of hours. However, the 6335 has a typical lifetime of 300 hours. Two 6335 lamps are included with the TLS260-250Q. The 60043 socket adapter required to use the 6335 in the Research Lamp Housing of the TLS is included with the system.

Tunable Broadband Output With 5 nm, 10 nm, 20 nm, and 30 nm Resolution Selection

The TLS260 series includes a Cornerstone 260 monochromator in its setup. This monochromator is based upon an asymmetrical in-plane version of a Czerny-Turner monochromator. The optical configuration is designed to ensure high resolution and maximum throughput, while rejecting stray light and minimizing aberrations. A fixed slit assembly is at the input port and a micrometer driven slit is at the output port of the monochromator. This allows for flexibility and convenience in adjusting the slit widths of the monochromator to meet the resolution and light throughput needs of any application. A simple input command from the user coordinates the operation of the integrated filter wheel and monochromator to output broadband white light, or monochromatic light from the TLS260. 600 μm (18 mm height) and 1240 μm (18 mm height) wide fixed slits are included with the TLS260.

Rotating Output Flange

The 1.5 inch output flange of the TLS260 is an optical assembly incorporating a protected aluminum coated mirror. This mirror's off-axis replicated parabolic design features the focal point displaced from the mechanical axis, eliminating the typical shadow effect observed when a detector or light source is placed at its focal point. The output flange has 360˚ freedom of rotation, providing flexibility and convenience in installing the TLS260 into existing measurement systems.

Pre-Assembled and Pre-Aligned

The TLS system arrives as a single, fully assembled unit ready for plug and play operation. Optics are pre-aligned. All necessary interconnection cables are included and all hardware is mounted securely to the TLS baseplate for convenient setup and transportation.

TLS260-300X Lamp Installation and Alignment

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.

TLS260-250Q Lamp Installation and Alignment

When the 6335 QTH lamp inside the TLS system has reached its end of lifetime and needs replacement, changing the lamp is as simple as unplugging the old one and plugging in 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 to the left.

Motorized Filter Wheel with Order Sorting Filters

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 . 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.

Built-in Detector Readout and Simple Communication Interface

The integrated OPS power supply operates the Xe arc lamp or QTH lamp of the TLS with high light output intensity stability. An ability exclusive to the TLS260 series, the OPS power supply is also capable of reading the output current of any unamplified Oriel detector. Unlike TRACQ-BASIC-V066, the OPS power supply simplifies setup by not requiring an external meter to display real-time Oriel detector current readings.

Integrated TLS Utility Data Acquisition and Control Software

The OPS power supply integrated into the TLS260 includes TLS Utility, an instrument control and data acquisition software that enables the simultaneous monochromator operation and detector readout necessary for the following spectroscopy scans: Transmittance/Absorption, Time Interval, Quantum Efficiency, Spectral Responsivity, and Optical Power. TLS Utility is compatible with 32-bit and 64-bit versions of Windows XP, 7, 8, and 10. The power supply enables standalone PC control via USB 2.0 connection. Driver installation for all integrated components is simplified as TLS Utility automatically detects the Cornerstone 260 monochromator and drives all associated components.

Easy Monochromator Removal and Re-Installation

In order to receive the same repeatable, high quality light output the TLS260 demonstrated out of the box, returning the monochromator to Newport on a routine basis is recommended. Based on the years in service the monochromator has been used for, CS260-MAL-OPT1 or CS260-MAL-OPT2 is recommended. The baseplate mounting design of the TLS260 securely mounts the Cornerstone 260 monochromator and all other components of the system, but allows for easy removal and re-installation of the Cornerstone 260 when return to re-calibration procedure is necessary.

Compatible with Newport 2 Inch Lens Tube and Oriel 1.5 Inch Flanged Products

The output flange of the TLS260 is the standard Oriel 1.5 inch flange designed to be compatible with Oriel Detectors and Detection Systems. This flange can be removed to change the size of the output flange to 2.0 inch, making the TLS compatible with Newport's 2.0 inch sized , if a larger output beam diameter is required.

Each Unit Tested to Meet Oriel Standards

Each TLS260 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:

  • Optical power from 300 to 1650 nm for Xe source or 350 to 1650 nm for QTH source
  • Beam diameter and divergence angle
  • Light output stability
  • Wavelength accuracy and resolution

Arc Lamp Safety

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 an Ozone Eater.
