※

The wavelength rang e of Optizen 2120UV spect rophotometer is f rom ultraviolet ra diation

(190nm) to near infrared radiati on (1100nm). For this, deuteriu m lamp and tungsten -

halogen lamp is us ed as a light source. Two lamps are ch anged each other au tomatically

in 350~ 470nm range.

4) LCD Contrast Control

It controls br ightness level of LCD bac k light.

5) Lamp Change WL.

You can setup the wavelength for c hanging point of deuterium lamp and tungsten-halog en

lamp.

The range of the valu e that you can input is f rom 350nm to 470nm.

The default value is 370nm.

6) Initial Wavelength

You can set initial wavelength of Optizen. Incase set mainly used wavelength, you don’t need

to set wavelength every measuring time.

7) Clear Lamp Position
