Miniaturized calibration stimulus for on-board calibration of space optical systems.  The miniaturized stimulus for the onboard spectro-radiometric calibration of space optical instruments. It is based on an innovative, photonic based, tunable laser, consisting of a semiconductor gain section and photonic waveguide circuit. The laser output wavelength can be reproducibly tuned over a range of a few tens of nanometers.

Features-
•	The main MicroSpec application is the on-board calibration of small space optical instruments.
•	In-flight spectro-radiometric calibration is of paramount importance to increase the quality of data products.
•	The enabling technology is available over a wide wavelength range (500 – 2350 nm)
•	Multiple laser heads can be multiplexed to increase spectral coverage while using the same drive electronics.

Technical Specifications-
•	Wavelength specification: Central wavelength: 1530 nm, Tunability: 100 nm
•	Wavelength tuning accuracy:  < 1 nm
•	Output power: < 1 nm
•	Output power stability: ~ 1%
•	Wavelength tuning accuracy: < 1 nm
•	Volume: < 0.2 dm3
•	Mass: < 0.4 kg
•	Power consumption: < 10 W (operational), < 1 W (idle)

Applications-
•	Optical instrument in-flight calibrator
•	Spectral calibration
•	Radiometric calibration
•	Optical alignment (e.g. keystone correction)
•	Optical instrument on-ground calibration and characterization (C&C)
•	Compact package with excellent performance
•	Use the same calibrator for the C&C campaign and in-flight
•	Other applications
•	Spectroscopy
•	Interferometry
