CORNERSTONE 260 MONOCHROMATORS

3.4 MOUNTING OPTIONS
The ability to mount the monochromator simplifies setup and alignment of the optical system. The
mounting plate or kits also helps ensure consistent results over time, as the monochromator
cannot be accidentally moved out of position. The following options are available for securing the
Cornerstone 260:
• Mounting plate
• Mounting kit to couple with Oriel’s Research Lamp Housings
• Optical rods
The 74105 Mounting Plate is used to secure a Cornerstone 260 Monochromator to an inch or
metric optical table. The plate adds 0.25 inch [6.35 mm] to the optical height. If the Cornerstone
260 will be used with Oriel’s research lamp housing, consider using the 74104 mounting kit.
The 74104 Mounting Kit connects the Cornerstone 260 monochromator to an arc lamp or quartz
tungsten halogen light source. This kit is compatible with Oriel's Research Lamp Housings that
hold 50 to 250 watt lamps. It includes a base plate, a flexible light shield, a 1.5-inch diameter
focusing lens and lens holder. All the hardware required to mount the lamp housing and
monochromator to the base plate is provided. The mounting kit's base plate uses four adjustable
leveling feet. The feet may be removed to secure the base plate to an inch or metric optical table.
The most economical option is to use optical rods and rod holders to mount the Cornerstone 260
to an optical table or breadboard. On the monochromator’s mounting surface, four #1/4-20
threaded holes may be used to install standard optical rods. Care should be taken to ensure the
instrument is level and secured well enough that its location remains consistent over time, even if
the instrument is bumped or components coupled to the ports.
