Figure 45. The polarizer attachment in the DRA.

The polarizer assembly uses the same base mount as the double aperture apparatus.

Install the polarizer assembly into the accessory as follows:

1. Insert the base mount for the polarizer into the locator holes in the accessory base

plate as shown in the figure below. Fasten the device to the accessory base plate using the

M5 socket head screw provided and a 4 mm hex wrench.

2. Click the Windows Start button, then Programs, then Cary WinUV, and then Align.

Turn power to the spectrophotometer on. Install a beam blocker at the reference beam

and sample beam entrance ports to the sphere and configure the sample beam for white

light operation.

3. Remove reflectance standards from the reference and reflectance ports. Remove the

centre-mount port plug.

4. Slide the polarizer optic into the base mount slot. The optic should be oriented in the

direction shown in the figure above.

5. Observing the sample beam profile as it strikes the entrance aperture to the polarizer,

adjust the height of the device so the sample beam penetrates the optic unclipped.

6. Remove the blocking device from the sample beam. Check the sample beam

alignment at the reflectance port using a piece of translucent paper. Make any

adjustments to mirror M3 as necessary.
