The TPIR-785 from Teledyne Princeton Instruments (TPI) is a Raman Spectrometer that operates at a spectral length from 80 to 2250 cm-1. This spectrometer has a spectral resolution of 5 cm-1 and has an aperture ratio of f/2. It has an adjustable slit width from 10 μm to 3 mm and supports the USB 3.0 interface for serial communication.
The TPIR-785 has a 785 nm Raman probe which has a focal length of 10 mm and has a round to linear fiber bundle for high light-collection efficiency. It also incorporates a 785-nm multimode laser that can handle a power of 475 mW (software adjustable) and has a cuvette holder that is based on proprietary CUBE accessories which are ideal for routine measurement. The spectrometer consists of two detectors - PIXIS 100/400 BR EX4 and BLAZE 100/400 HR. The PIXIS 100/400 BR EX4 features a deep cooled scientific CCD camera that functions as per eXcelon Technology. It eliminates fringes and improves QE in the NIR range. The BLAZE 100/400 HR offers 3x higher NIR sensitivity in a large-format CCD camera and exhibits 70% QE at 1000 nm. Both the detectors have a pixel array of 1340 x 100/400 with a pixel size of 20 x 20 μm.
This Raman spectrometer supports LightField for system control and data collection, SDKs in Python(Python Software Foundation), LabVIEW (National Instruments), and MATLAB (MathWorks) software. It is available in a module that measures 61 x 44 x 19 cm and is ideal for biology and medical research, petroleum and chemical, forensic, security and military, pharmaceutical, food and agriculture, material research, and environmental applications.
