SR-3501 Portable Spectroradiometer with Expanded Spectral Range
The SR-3501 is a portable spectroradiometer that provides an expanded spectral range from 280-2500nm. Features include:
- Spectral resolution
- 4nm @ 280-1000nm
- 9nm @ 1500nm
- 7nm @ 2100nm
- Data output is 1nm increments with 2221 channels reported
- Factory calibrated for radiance/irradiance using NIST traceable source (depending on optics selected)
- Compact design, portable instrument
The SR-3501 is well-suited for radiance/irradiance measurements as well as test and measurement of solar simulators. The SR-3501 and SR-1901 are used for continuous solar simulators:
- SR-3501: 280-2500nm - one silicon photodiode array
detector and two InGaAs photodiode array detectors - SR-1901: 280-1900nm - one silicon photodiode array
detector and one InGaAs photodiode array detector - Spectral match to AM0, AM1.5, and AM1.5 global tilt
Equipped with a fiber optic cable and right angle diffuser, these spectroradiometers can measure continuous output over user-defined time periods to ensure long-term stability.
