Example of a 3-D spectral plot

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.
