Fitting the optical bench
Before you begin, make sure that:
•
The instrument’s external beam port is fitted with a suitable window;
•
There is at least 500 mm (18 inches) of free bench space to the right of the instrument;
•
An external accessory bracket is fitted in the handhold on the right of the instrument;
•
The spectrometer is switched off and disconnected from the power supply.
1.
If necessary, remove the fixing block from the underside of the left edge of the optical
bench.
Use a suitable hexagonal key to undo the two M6 socket head bolts from the threaded
fixing positions at the near left and far left corners of the optical bench until the fixing
block is free.
2.
Place a spring washer and then a plain washer on each bolt, push the M8 bolts supplied
through the plain holes in the fixing block, and then carefully align the bolts with the
threaded holes in the external accessory bracket.

3.
Use a 6 mm hexagonal key to turn each bolt until it engages in the external accessory
bracket, make sure the bolts are perpendicular to the bracket, and then carefully and
evenly tighten the bolts.
NOTE: If these bolts engage incorrectly, the accessory may be misaligned or its fixings
damaged.
