Introduction and Help
For a complete guide to the Cary hardware and
open the Cary “Scan” program and click on the
Help
tab.
For the basic theory of diffuse reflectance
measurements, useful diagrams of the diffuse
reflectance adaptor (DRA), alignment tips and
procedures, and descriptions of all the DRA
accessories (VATH, Small Spot Kit, and center
mount holders) go to Help > Help topics >
Accessories > Cary 4000/5000/6000i > Solid
Sample > external DRA
To learn more about the software and taking
measurements in the Scan menu, go to Help >
Help topics > Software Applications > Scan
Turning the instrument on:
Open the Cary Scan program on the taskbar or Desktop
The DRA must to be fully closed in order for the instrument to initialize. Turn on the
instrument (0/I switch on the lower left side of the front of the instrument). In the Scan
program, watch the lower left corner to see the status of the instrument. When the
traffic light is green (top center of screen), then a scan can be run.
Basics configuration and alignment
There are four positions in which the sample can be placed for use with the integrating
sphere (see Figure 1 andFigure 2).
1.
The entrance slot to the integrating
sphere is for normal incidence diffuse
transmission
2.
The rear slot is for normal incidence
diffuse reflection
3.
The center mount holder allows for
variable angle diffuse reflectance and
transflectance measurements
4.
In addition, the VATH (variable angle
transmission holder) accessory can be
put in front of the integrating sphere for
variable angle specular transmission
measurements. If you would like to use
