1.  Introduction   

 

1-1. Standard Composition 

Typical  Miniature  Spectrophotometer  consists  of  four  basic  elements:  SEC2000 

(detector), Visual Spectra 2.1 (program software), SEC2000-TH (light source for Visible- 

Near  infrared)  or  SEC2000-DH  (light  source  for  UV-Visible),  and  SEC2000-CUV 

(cuvette holder).
