MountainSphere for irradiance
Spectral measurement of absolute irradiance from 200 nm to 2500 nm
The Irradiance variants of the MountainSphere can be calibrated together with the entire optical setup to measure the absolute spectral irradiance.
Depending on the application, different wavelength ranges from 200 nm to 2500 nm are available.
The calibration points can be aligned with the wavelength points of the used spectrometer(factory calibration).
Alternatively, the calibration lamp MountainSource-100-P can also be used for regular on-site calibration of the optical system.
This calibrated halogen light source can be connected to the used MountainSphere and the irradiance can be adjusted to the light you want to measure.
