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 with laser
excitation 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
