The Soma Spectroradiometers are designed to accurately measure the spectral irradiance of sunlight. Used in conjunction with a solar simulator and included software, the light source can be tested and quantified.
This instrument utilizes a proprietary high-efficiency diffraction grating spectrometer and the S-2441C/2442C models add the ability to measure pulse-type solar simulators with an included trigger collector. This high-performance spectroradiometer is inexpensive and compact, making it ideal for all users.
The Soma S-2440C/2441C features a wavelength of 300~1100nm, 5nm resolution, and 2.5~1,000msec exposure time and the S-2442C decreases exposure time to 1~1,000msec. It operates off of Windows 2000/XP/Vista (32 bit) and has both spectral irradiance, ASTM and JIS output calculations.
The Soma Spectroradiometers can measure pulse-type, as well as non-pulse-type, solar simulators.
