3. OPERATING INSTRUCTIONS
3.1 INITIAL SET UP
Position the Wavemeter
jr
on a firm horizontal surface. It is important that this
surface be horizontal and stable to ensure proper operation of the internal
interferometer scanning mechanism. The upper front panel is swivel mounted to
accommodate a wide range of viewing angles. Tilt the upper front panel to a
comfortable viewing angle.
NOTE: Check that the 115/230 VAC on the rear panel is correctly set and attach the AC
line cord. If the initial operational check has not been performed, refer to Section
2.2 of this manual. For 100 VAC operation, refer to Section 3.13.
3.2 BEAM RECEIVER MOUNTING
The optional beam receiver accessory consists of an optical coupling head (BC-1)
attached to a 3 meter FC connector terminated patch cord (PC-F) which provides the
input beam for the instrument.
CAUTION: The fiber optic cable and internal components of the coupling head are made of
glass and must be handled with care. Do not drop, bend sharply, stretch, or
otherwise stress the cable particularly in the vicinity of the connector. Permanent
damage to the cable can result. Do not drop the coupling head.
Optical power incident on the beam receiver should not exceed 100 milliwatts over
the entire operating range of 400 to 1800 nm. For beams smaller than the input
aperture of 2.5 mm, the maximum allowable power must be adjusted downward to
avoid exceeding safe power densities. Optical powers in excess of these limits
may cause irreparable damage to the assembly.
To install the beam receiver, first remove the dust covers from the fiber optic input
on the rear panel of the Wavemeter
jr
, the BC-1 optical coupling head and both ends
of the FC connector terminated patch cord. Store these dust covers for future use.
Connect the2 fiber optic cable to the FC connector on the rear panel of the
instrument and to the BC-1 optical coupling head. There is a “keyed” position for the
connector. Rotate this into position before tightening the knurled lock ring.
