4. Turn on the instrument on and allow it to warm up (approximately 2 hours).

5. Set the instrument to Zero order using the Align application. See Installation step 14

6. Once the instrument is warmed up, remove the reflectance standards from the ports (if

they are currently loaded). Load the reflectance lens into the small spot kit lens mount.

The reflectance lens is marked "R", the transmission lens is marked "T", and the centre-

mount lens is marked "C". The lens should be oriented so the arrow points toward the

integrating sphere. Gently rotate the lens until it clips into place. The grooves in the

outside of the lens sit on the clips on the mount.

7. Remove the transmission holder. (The transmission holder may clip the beam,

reducing the energy entering the sphere.)

7. Install the DRA into the instrument. Turn the instrument ON and allow it to initialize.

8. Install a beam blocker over the reference beam entrance port.

9. Find the sample beam at mirror M2 and centre if necessary.

10. Fully close the iris. Look at the top left hand corner of M3 and observe the beam on

the back of the iris. When the iris is closed to its smallest opening size, the beam should

be taller than the hole but centreed in the iris opening. To realign the iris assembly in the

beam path, first loosen the thumb screw that secures the two sections of the iris assembly

together. Move the top portion of the iris assembly, sliding it laterally, until the beam is

centreed on the iris opening. Retighten the thumb screw.

11. Fully open the iris. Dim the light in the room.

12. Adjust mirror M2 to centre the beam on the M3 SSK mirror. See Alignment

for

instruction on aligning the mirrors.

13. Hold the translucent paper just outside the open reflectance port. Adjust the M3 SSK

to centre the sample beam within the reflectance port opening. It may be necessary to

adjust the aperture size of the iris or relocate the lens mount along the dovetail rail to

achieve the desired spot size and make a note of the position of the iris.
