Transmission Preform Holder
This option provides an adjustable holder for measuring transparent preforms at the transmission port of
the UltraScan VIS. The holder is appropriate for preforms with a shaft diameter between 10 and 40 mm
and a length of at least 50 mm.
Complete the following steps to install the holder into the instrument.
1. Position the holder so that the flat side is aligned at the opening of the sphere at the front of the
transmission compartment. The base should be down on the floor of the transmission compartment
with the spring screws facing out into the transmission compartment.
2. When properly aligned, the holes in the base of the holder will align with holes in the floor of the
transmission compartment. Place a thumbscrew in each of the holes and tighten until snug.
Use the preform holder as follows:
1. Standardize the instrument in TTRAN mode on air, using 0.375 inch (9.525 mm) as the area view .
When prompted for the black card, slide it between the preform holder and the transmission port.
2. Open the holder. It is easiest to do this by placing an index finger between one of the metal pegs on
top of the holder and the transmission port and resting the thumb of the same hand on the end of the
corresponding spring screw. Pull the index finger toward the thumb until the holder provides an
opening large enough for insertion of the desired preform.
3. Insert the preform into the holder as far as the preform will go with the threads up. Then close the
holder and confirm that the preform is held securely in place.
