LEOI-100 Experimental CCD Spectrometer is a general-purpose spectrum measuring instrument. It uses a linear CCD as receiving unit capable of real-time acquisition and 3-dimensional data display. LEOI-100 is a valuable instrument for studying the spectra of various substances or calibrating optical probes.
LEOI-100 consists of a grating monochromator, a linear
CCD unit, scanning system, electronic amplifier and USB interface. This instrument integrates optics, precision
machinery and electronics in one unit. The optical element adopts a C-T model shown to the left.
Both the entrance and exit slits are straight with a width
continuously adjustable from 0 to 2 mm. The beam from
the light source passes through entrance slit S1 (S1 is on
the focal plane of reflectance collimation mirror), then reflected by mirror M2. The parallel light strikes grating G.
Mirror M3 forms the image of diffracted light coming from
the grating onto S2.
To calibrate the spectrum, at least two standard spectral lines are need within the spectral range of current working window. A calibration spectral lamp with multiple spectrum tubes is optional. By selecting a proper spectrum tube, the required standard spectral lines are available.
