Ventana Data Sheet
Description
The Ocean Optics Ventana series of high-sensitivity spectrometers maintain high sensitivity and
throughput for low-light level applications such as Raman analysis or fluorescence without the need
for long integration times or high-power excitation sources. This spectrometer uses an HD Volume
Phase Holographic (VPH) Grating, low f/# design and anti-reflection coatings to allow more of the
coupled light into the spectrometer. The internal optics have been selected to minimize light loss and
provide superior image quality. The Ventana models include the following:
•
•
•

•

Ventana-785-Raman -- preconfigured for 785 nm excitation Raman measurements; includes a
cooled (down to 15 °C) NIR-enhanced, back-thinned detector with low noise electronics
Ventana-532-Raman -- preconfigured for 532 nm excitation Raman measurements
Ventana-785L-Raman -- preconfigured for 785 nm excitation Raman measurements with
integrated 785 nm laser; free-space coupling to maximize sensitivity; front-end laser matches
the ƒ/1.3 spectrometer input to maintain maximum efficiency; hard-coated filters used to
maximize transmission and minimize Rayleigh scattering
Ventana-VIS-NIR -- preconfigured with 430-1100 nm bandwidth, 50 micron slit; low f/2;
configuration optimized for low signal VIS-NIR measurements (430 to 1100 nm) such as
fluorescence; low f/# with custom lens design and optic coatings providing superior image
quality and high transmission

All model Ventana spectrometers use the Hamamatsu S11510-1006 back-thinned, reduced etalon
detector except for the VIS-NIR version, which uses the Hamamatsu S10420-1006 detector. For
