Measurements With MAVOSPHERE

Integrating Sphere 1/07.14

This document describes the measurement procedure for MAVOSPEC in combination
with MAVOSPHERE 205, MAVOSPHERE 500, MAVOSPHERE 1100 and
MAVOSPHERE 2000.

1 Configuration of measurement workplace

Equipment used for the measurement consists of:

 MAVOSPHERE together with spectrometer MAVOSPEC
 USB source controller (sphere controller)
 PC with installed and configured GL Spectrosoft

During factory calibration process, the calibration profile for MAVOSPHERE had been
stored in memory of spectrometer used for calibration. MAVOSPHERE gives correct
results only when used together with the spectrometer containing the valid profile for
this specific sphere.

Before executing measurements the sphere adapter must be mounted on MAVOSPEC
and then spectrometer must be installed in an appropriate port of the sphere.
Afterwards the spectrometer has to be connected to the PC via USB cable.

The auxiliary light source, which is part of the MAVOSPHERE, should be connected to
the sphere controller with the Jack connector. The sphere controller must be connected
to the PC with USB cable as well as to the power. The power switch should be turned
on.

Please check the number of COM port on PC which is associated with the sphere
controller. This number must be configured in GL SpectroSoft as described in chapter 2
before the measurements could be executed.

Before actual measurementscan be executed, the dark current calibration procedure
must be done. The dark current procedure is described in the MAVOSPEC manual.

2 The calibration of the self absorption

Before further steps, the support for the sphere controller must be enabled in the
MAVOSPEC settings.
