STS-VIS
Microspectrometer
Visible Spectral Analysis in a Tiny Footprint
The STS-VIS Microspectrometer offers powerful performance in a small
footprint. At just 50 mm square and weighing ~60 g (2 oz.), the STS
delivers optical resolution, sensitivity and stability comparable to much
larger, more expensive spectrometers. Its rugged design and great
unit-to-unit reproducibility make STS especially attractive for integration
into devices and other applications where a small footprint is required.
Whether you are performing low-concentration absorbance measurements
or high intensity laser characterization, the STS-VIS delivers the
performance you need.

Small Size. Big Performance.
The STS-VIS is small, but its performance is comparable to spectrometers more than twice
its size. Using a unique optical design and a CMOS array detector, the STS-VIS delivers
a high signal-to-noise ratio (>1500:1) and a wide dynamic range (4600:1), making it
ideal for measurements from low-concentration absorption to high intensity light and
laser characterization. Reliability was designed into the STS-VIS, where a high thermal
stability and low baseline drift ensure your data stays accurate, even under changing
environmental conditions.

Configuration and Integration
By selecting the appropriate entrance slit for your STS-VIS the resolution of the
measured spectrum can be optimized for your application. Choose a narrow slit for
light-rich applications where resolution is most important. For low-light applications,
select a larger entrance slit allowing more light into the spectrometer.
The STS-VIS easily integrates into your small device or sits comfortably next to your
process line for quality control measurements. With several software control options,
including drivers that allow direct control of the spectrometer, the STS works with your
existing systems to help you get the valuable answers you need.
The STS is also available in versions for the UV (190-650 nm) and NIR (650-1100 nm). Ocean
Optics offers a complete line of light sources and sampling accessories to complement your
STS spectrometer. Contact us today to configure the best system for your application.
