9) Calibration Mode (Secret Key:’9’)
Optizen has self-correction mode for wavelength and cell holder position. Wavelength
calibration mode checks the 0th order position of grating and the peak wavelength (656.1nm)
of Deuterium lamp.

※The wavelength range of Optizen 2120UV spectrophotometer is from ultraviolet radiation
(190nm) to near infrared radiation (1100nm). For this, deuterium lamp and tungsten-
halogen lamp is used as a light source. Two lamps are changed each other automatically
in 350~470nm range.
4) LCD Contrast Control
It controls brightness level of LCD back light.
5) Lamp Change WL.
You can setup the wavelength for changing point of deuterium lamp and tungsten-halogen
lamp.
The range of the value that you can input is from 350nm to 470nm.
