The Ventana 785L combines the Ventana 785 Raman spectrometer with a 120 mW TEC and VPG stabilized 785 nm laser module. Ventana 785L is a high-performance spectrometer providing exceptional throughput and sensitivity in a small footprint. This system provides ultra stable performance over time and temperature. Designed to minimize light loss and maximize throughput, Ventana 785L is optimized for Raman measurements with 785 nm laser excitation.
High performance hard coated filters are used to maximize transmission and minimize Rayleigh scattering. Free space coupling eliminates fiber related signal loss providing high sensitivity for fast measurements. With its smart, integrated design and compact footprint, Ventana 785L is a cost-effective alternative to integrated benchtop systems with no compromise in performance.
