INTRODUCTION
The Photo Research Inc. Spectra® Modular Systems (PRISMS) line of versatile spectral measurement solutions combines the research grade accuracy, repeatability and reliability that
Photo Research has been providing for over 70 years into solutions that can readily adapt to
any application via an industry standard SMA terminated fiber cable. Now, VIS / NIR spectral,
photometric and colorimetric testing can easily be performed on LED’s, luminaires, displays,
projected images – virtually any configuration. The fiber optics link makes the PRISMS series
ideal for interfacing to integrating spheres (luminous flux / radiant flux), luminance / radiance
probes, illuminance / irradiance probes, and luminous intensity / radiant intensity probes – all
at an extremely compelling value for reference grade instruments. This versatility means that
whether you have an R&D, QC or production application there is a configuration that will
provide a solution. If one of our “standard” solutions doesn’t quite fit, PRISMS is designed to
easily interface to a solution that does. The PRISMS series consists of 5 products – the Spectra®
MS6, MS730, MS735, MS740, MS745. All are based on our field proven Pritchard Optics based
spectroradiometers insuring world class performance. Importantly, if none of the following
products meet your needs, just contact us and we will work with you on a custom solution!

MS6
The MS6 is ideal for those applications
requiring a medium resolution, medium
sensitivity solution at an extremely
affordable price. See the specifications
sheet on the back cover for more details.
MS730 / MS735
LED and lighting device manufacturers are constantly striving to
produce more and more powerful
devices creating the need for a
testing solution for these products.
The MS730 and MS735 are available
to address those needs. It is intended to provide high resolution (1 nm),
high intensity and high speed testing
of today’s high powered devices.
The MS730 covers the visible
spectrum while the MS735
measures into the NIR.
MS740 / MS745
These two systems are designed
for those applications requiring
ultra-high speed at low light
conditions and is ideal for the
testing of low to medium intensity
LED’s for lumens (in an
integrating sphere). The MS740
is a visible wavelength solution
while the MS745 extends the
measureable spectral range to
1080 nm making it ready to test
NIR LED’s or other devices that
go just past the visible spectrum.
SOFTWARE
Each PRISMS system is supplied
with SpectraWin 2 Lite software –
a Windows (Vista, 7 and 8) based
control and data analysis
program designed for ease of use.
The systems can also be controlled
using the built-in text based
communications protocol –
Remote Mode software. For
applications where it is preferable
to communicate with a driver,
an SDK is optionally available.
