FluoroMax Fluorescence Spectrofluorometer
. The gratings themselves are plane, blazed gratings that avoid the two major disadvantages of the more common concave holographic gratings: poor polarization performance and inadequate imaging during scans that throws away light. The unique wavelength drive scans the grating at speeds as high as 80 nm/s. The grating grooves are blazed to provide maximum light in the UV and visible region. The Reference Detector. Before the excitation light reaches the sample, a photodiode reference detector... (read more)
