Introduction

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, a scanning system, and an electronic amplifier with USB interface. This instrument integrates optics, precision mechanics 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 a collimation mirror), then reflected by mirror M2. The parallel light strikes grating G. Mirror M3 forms the image of the diffracted light coming from the grating onto exit slit S2.

 

To calibrate the spectrum of a selected work window, two standard spectral lines are needed within the spectral range of the work window.
