Figure 12: Simplified beam diagram of the accessory with the sphere cap in the 'D'

position. The specular component is reflected back out of the sphere onto the lens.

The reflection from the lens should be about 10 mm from the transmission port.

5. Re-tighten the screws and re-check the alignment, to see if any lens

adjustment is necessary.

6. Position the sphere cap so that the 'S' mark is facing up. If any part of the

reflected beam exits the transmission port, repeat the alignment and specular

component checks.

Hot Tip

Place the alignment target at the edge of the transmission port (without

blocking the beam from the lens) and rock the mirror over the reflectance port

to identify the reflected beam. When the mirror is placed over the reflectance

port, no part of the beam should be observed exiting the transmission port.
