Teledyne Princeton Instruments Introduces Raman Spectrometer for Limitation-Shattering, High-Sensitivity Performance in NIR

Teledyne Princeton Instruments, a Teledyne Technologies company,  and world-renowned manufacturer of scientific imaging and spectroscopy equipment, is pleased to introduce its new TPIR-785 Raman spectrometer, a fully integrated system that leverages leading-edge spectrograph and camera technologies to optimize performance in the near-infrared (NIR) region. The TPIR-785 is an ultra-high-sensitivity spectrometer for NIR Raman spectroscopic application areas such as biology, medical research and life science where NIR excitation lasers (785 nm and 830 nm) are preferred for their low fluorescence and deeper penetration depth when measuring biological tissues.

This new system utilizes an f/2 spectrograph with custom-designed lens optics to provide the highest light throughput and imaging quality in the NIR spectral range. The TPIR-785 also allows users to tailor the instrument’s performance for optimal spectral resolution (up to 5 cm-1) or optimal spectral range (up to 80 – 3650 cm-1). The system includes a 785 nm Raman probe, a universal fiber adaptor, a manual adjustable slit, and a high-power and temperature-stabilized 785 nm laser.

The TPIR-785 Raman system uses a proprietary CCD that delivers unmatched NIR quantum efficiency (greater than 70% at 1000 nm). This “super-deep-depletion” sensor has a 1340 x 400 array composed of 20 µm square pixels and can be thermoelectrically cooled to -90° C for ultra-low dark current, allowing integration times from 10 µs to hours. The detector boasts spectral rates higher than 1 kHz, offers readout speeds up to 16 MHz, and employs two readout ports. A new NIR optimized eXcelon™ process eliminates etaloning fringes and improves quantum efficiency. The high imaging quality spectrograph paired with large format detector allows the use of large fiber bundles for improved collection efficiency or Raman imaging measurement.

In addition to its versatility, the new system is easy to use and features push-button data collection. The underlying technologies in TPIR-785 are already proven in cutting edge research, including cancer diagnostics, non-invasive glucose monitoring and cell cytology. We are confident that the integrated TPIR-785 system will enable more researchers to achieve further breakthroughs in these areas.
