Del Mar Photonics presents new unique fully computerized powerful laser spectrometer for research studies demanding fine resolution and high spectral density of radiation within UV-VIS-NIR spectral domains.
This fully automated high-resolution spectrometer based on Tekhnoscan's CW narrow-line Ti:Sapphire laser, model LaserScan TIS-FD-08/A, comes as a perfect embodiment of modern ideas and technology innovation in the field of smart laser spectrometers. Novel advanced design of the fundamental laser component implements efficient intra-cavity frequency doubling as well as provides a state-of-the-art combined ultra-wide-tunable Ti:Sapphire & Dye laser covering a super-broad spectral range between 275 and 1100 nm.
The spectrometer includes, as its base, a CW ultra-wide-tunable narrow-line
laser, high-precision wavelength meter, an electronic control unit driven
through USB interface as well as a software package. Positions of wavelength
selection components in the laser as well as the position of the non-linear
crystal are precisely controlled with the help of a closed-loop feed-back system
including a wavelength meter. The spectrometer is fully controllable through a
user-friendly computer interface that offers a variety of modes for setting and
scanning of the radiation wavelength as well as different modes of data
acquisition and recording.
The LaserScan TIS-FD-08/A features LabWindows™ based software running under
Windows™ XP/Vista. For acquisition of experimental data an 8-channel 14-bit ADC
is used with quantisation frequency of 3 MHz and channel multiplexing frequency
3 MHz.
The spectrometer is designed for wide-range spectral studies and
characterization of quantum semiconductor structures, meta-materials,
bio-objects as well as for nano-, bio-technological applications, and quality
control.
