The SP-100 spectro-radiometer from Orb Optronix includes an interchangeable head attachment to allow measurement of spectral radiance, irradiance, and flux. The system is easy to use, with automatic calibration when a new head is attached.
For luminance and radiance measurements, the SP-100 features an internal target spot laser that projects a circular image onto the device under test, eliminating the inconvenience of a viewfinder. The SP-100 features a USB connection, and includes a complete software package.
