Compact spectrophotometer |
| abstract |
A portable spectrophotometer (100) includes a rotating wheel (214) provided with a plurality of filter characteristics in the 400 to 700 nanometer wavelength range and operated at a constant speed. The filters are moved between an optical conduit (210) and a photoelectric sensor (220) as the wheel is rotated. Light reflected from the object sample is conducted through the optical conduit (210) and focused on the optical sensor (220) by means of a focusing lens (252). A side sensor (222) receives light from one of the three lamps (206) through the filters as the wheel is rotated and provides output signals which are used as reference signals for the individual filters. An integrating sphere (512) with an aperture (541) for conducting specular-included light reflected from the object and an aperture (543) for conducting specular-excluded light from the object is incorporated with a rotatable filter wheel (520), with a plurality of filters having filter characteristics in the 400-700 nanometers wavelength range. |
