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 lters are used to maximize transmission and minimize
Rayleigh scattering. Free space coupling eliminates ber related signal loss providing high
sensitivity for fast measurements. With its smart, integrated design and compact footprint,
Ventana 785L is a cost-eective alternative to integrated benchtop systems with no
compromise in performance.

Features:

· Low f/# design for high throughput and sensitivity

· Anti-reection coatings and optics placed in an optimized conguration minimize light
loss and provide superior image quality

· High eciency HD Volume Phase Holographic Grating for low stray light and minimal
light loss

· Front end laser matches the ƒ/1.3 spectrometer input to maintain maximum eciency

· 120 mW TEC and VPG stabilized integrated 785 nm laser module

· Back-thinned, cooled silicon detector with excellent quantum eciency combined with
low noise electronics
