The WP 248 from Wasatch Photonics is a Raman Spectrometer that operates at a wavelength of 248.6 nm. It has an in-built long-pass filter for Rayleigh scatter rejection and is available with a choice of an ambient or TEC-regulated detector. This option allows the balancing of the required signal to noise (SNR) and temperature stability. The spectrometer has a resolution of 14 cm-1 at 25 μm slit and has an integrated lens with a pixel size of 14 x 14 μm. It requires a DC supply of 12 V and has a current consumption of less than 500 mA.
This Raman spectrometer has a superior optical design based on a patented transmissive VPH grating and has an f/2.0 input aperture to capture more light. It is available in a module that measures 30.2 x 17.9 x 7.5 cm with a USB 2.0 type B connector and is ideal for research and cost-effective UV resonance application.
