Development of a monochromatic, uniform source facility for calibration ofradiance and irradiance detectors from 0.2 mu m to 12 mu m

A radiometric source facility is being constructed with narrowband, widely tuneable lasers covering the wavelength range approximate to 200 nm to 12 m u m. The laser beam will pass into an integrating sphere and the output wil l be large-area, highly uniform, and monochromatic. This facility will be u sed to make a wide variety of radiometric measurements, such as radiant pow er, radiance, irradiance, transmittance and reflectance.
