2.1 Mount an Accessory
In general, the procedure to mount an accessory to the entrance slit is:
1.
Place the accessory directly against the face of the slit body.
2.
Using four (4) 8-32 screws typically provided with the accessory, secure the accessory
to the slit body.
Light sources fitted with light collection/focusing optics are normally factory-aligned to the
standard slit.
NOTE:
In some instances with light sources, there is limited access to the
bottom two screw holes. In this case, Princeton Instruments
provides special slotted holes in the light source housing to
facilitate mounting the source to the slit.
2.2 Slit Width Adjustments for Manual Slits
NOTE:
Information in this section applies to the following manual slit
models:
• 716-1 Manual Bilateral Slit;
• 716-MS Kinematic Slit.
The slit width of each bilateral slit assembly (716 type) is adjustable from 0.010 mm to
3 mm (10 µm to 3,000 µm) by a micrometer knob located on the top of the slit housing. The
micrometer knob is graduated in 0.010 mm (10 µm) increments.
Each clockwise revolution of the micrometer knob increases the slit width 0.25 mm
(250 µm.) For maximum reproducibility, the slit width should be set in a clockwise
direction (i.e., increasing slit widths,) each time it is changed. See Figure 2-2 and
Figure 2-3 .
CAUTION!
!
The micrometer knob should not be rotated below a reading of
0.00 nor above 3.00. A micrometer setting of less than 0.010 mm
(10 µm) should not be used, because a stop is provided to prevent
the slit jaws from contacting each other.
Damage may occur if slit jaws are opened more than 3.0 mm.
