INPUT AND OUTPUT SLITS
To operate any monochromator, slits are required at the input and output port. The slit assemblies
offered with the Cornerstone 130B all have 1.5-inch male flanges, allowing them to be easily connected to
the wide variety of Oriel accessories and instruments.
Note: The slits need to be the same width and height at the input and output ports. A wider input slit
when compared to the output slit results in more stray light inside the instrument. A wider output slit wit h
respect to the input slit will not increase throughput.

FIXED SLITS
The fixed slits slide into the 77294 holders at the input and output port. The width and height
cannot be adjusted, but may be individually replaced with other slit sizes. Fixed slits are a low cost
alternative to micrometer adjustable slits, and provide excellent repeatability. They are a good
choice when only a few slit sizes are required.
Fixed slits are sold separately to allow customized choices based on the needs of the applicat ion.
When ordering, be sure to purchase two fixed slits of the same model
– one for the input port, and
the other for the output port. Insert the slit as shown, with the label facing outward. Be sure that it
is fully inserted into the holder’s slot to ensure the best performance and repeatability.
