2: Installing the OTS
Measuring Transmittance
To use the OTS to measure transmittance of lenses, windows, etc., be sure that light source cord is
connected with appropriate power (100-240V, 50-60Hz) to the rear of the OTS, and also the USB cord is
connected between the OTS and a computer on which the OTS software has been loaded.
► Calibration Procedure
1. Turn on the OTS by flipping the lighted rocker switch on the side of the lamp support arm to the
“On” position. If the light in the switch does not come on, check the power cord connections.
2. Double-click the OTS.exe application icon to open the OTS software. The OTS main screen
appears.

3. Set up spectrometer parameters by clicking the button.
4. In the Scan Parameters window, click the button and adjust integration time to a value
where the signal peak is between 3400 and 3600 counts, and with no signal saturation anywhere
in the spectrum. Then set scan average, and boxcar. (For example, integration time = 9, scans
averaged = 50, and Boxcar = 2). Close the window to return to the main screen.
