DESCRIPTION

4.4. OPTICAL SYSTEM

Optical System Block Diagram

A tungsten halogen 

lamp

 is used as the light source for the entire working range of the meter (340 nm to 900 nm). The tungsten 

halogen lamp produces a white light that is passed to a diffraction 

grating

.

The diffraction 

grating

 splits the polychromatic white light into the visible color spectrum, allowing for specific wavelengths to be selected.  

The light is then passed through an optical 

filter

 to reduce stray light and improve measurement accuracy. 

The internal reference system uses a 

reference photo detector

 to compensate for drifts due to lamp intensity, ambient temperature and 

environmental changes, providing a stable source of light.
Focusing 

lenses

 are used throughout the optical system to ensure all of the light is being collected. This allows a brighter, stronger signal 

to be received.
After the light exits the cuvette a final focusing 

lens

 is used. This reduces error from cuvette imperfection and scratches eliminating the 

need to index the cuvette.
