4.1 2996 Detector Optics
The 2996 Detector is an ultraviolet/visible light (UV/Vis) spectrophotometer with:
• 512 photodiodes
• Optical resolution of 1.2 nm per diode
• Operating wavelength range from 190 to 800 nm
The light path through the optics assembly of the 2996 Detector is shown in Figure 4-1.
