2.2 STRAY LIGHT REJECTION
Stray light may have a variety of origins. Its presence may be caused by a wide variety of design
and manufacturing factors. The level of stray light due to the dispersed radiation inside the
spectrograph is affected by the design of the instrument, its baffles and interior finish. The MS260i
incorporates a sophisticated design, proven materials, and a quality manufacturing system to ensure
high stray light rejection.
The amount of stray light measured on top of true signal will depend on many experimental factors
as well as the performance of the instrument. When comparing stray light specifications, it is
important to compare values that were measured under identical circumstances. The spectral
distribution of the source and the response of the detection system are often the dominant factors
when determining a stray light value.
2.3 AVAILABLE MODELS
The model number of each spectrograph reflects its features. Refer to the part number code to
determine the features present in the instrument. If the model number differs from the code, it is a
Special Order configuration. In that case, refer to the Sales Order of the instrument for more
information. Available standard configurations are listed on Newport.com. Please note that not all
configurations may be available.
