|LI-COR LI-1800 Spectroradiometer|
The LI-1800 provides a fast, accurate method to obtain spectral radiation measurements in the field or in the laboratory. Its compact design, internal microcomputer and innovative optical design provide the versatility to meet a wide variety of applications.
The LI-1800 optical system has three major components - a filter wheel, holographic grating monochromator and a silicon detector. The holographic grating monochromator has a wavelength range of 300-1100 nm (300-850nm optional) and has selectable wavelength drive intervals of 1,2,5,or 10 nm. The instrument's high efficiency silicon detector and autoranging electronics allow scanning rates of over 30 nm per second.
