1. Warnings
Use only the 5Volt 4amp power supply included with the SIR analyzer. Use of
any other power supply could result in permanent damage to the electronics.
Storage temperature: 0C to 45C
Operating temperature: 10C to 30C
2. Essentials of Operation.
The SIR spectrometer is based on a rotating grating and single point detector.
The rotating stage has a very high resolution positioning system and feedback
encoder which allows very high spectral resolution and repeatability.
The SIR system works well for continuous sources of light. When sampling
pulsed or modulated sources, the spectrometer must be synchronized with the
external source.
Please see the external triggering and interface section at the end of this
document for more information.
The rotating grating positional feedback is precisely timed with sampling of the
light through the high speed analog acquisition system.
The ideal sampling resolution is based on the slit width and the step size of the
encoder.
This relationship is shown below.
