THORLABS LFES1 Shelf for LFE Series Enclosure Frames

Introduction

The LFES1 Shelf has been designed to provide additional storage space within the LFE1220 and LFE1220W Optical Table Enclosures; it raises controllers and other equipment off the work-surface of the optical table whilst keeping them accessible. The shelf panel is slotted to improve air flow to equipment mounted on it, and to assist in the preservation of laminar flow within the enclosure environment. The hanging rails can be exchanged for any other length of XE25 extrusion to give a different hanging height; simply order four extrusions of the desired hanging length.

Multiple shelving units can be stacked as shown below.

Assembling the Shelf

The LFES1 Shelf is supplied as a preassembled shelf panel, four hanging bars, two mounting bars and all required fixings and tools.

Lay the shelf panel with the silver face down on the table and one corner protruding over the edge.
Hold a XE25 Series Hanging Bar under the protruding corner cube.
Drop an M6 x 16 mm Socket Screw through the corner cube and screw in to secure the XE rail flush to the cube (do not fully tighten the screws). Ensure that the lugs on the underside of the corner cube secure correctly in the holes in the end of the Hanging Bar.
Repeat steps 1 and 2 to fit hanging bars to the remaining 3 corners of the shelf.
Turn shelf so the hanging bars point up.
Place an attachment bar on top of the two hanging bars as shown below.
Fit a large M6 washer to two of the M6 x 40 mm screws supplied, then pass a screw through each end of the attachment bar and screw into the end of the hanging bars as shown. Do not fully tighten the screws.
Repeat steps 5 and 6 for the remaining attachment bar.
Tighten all M6 Screws.
Fitting the Shelf to the Frame
The LFES1 Shelf can be mounted to any face with Thorlabs XE profile slots. It is recommended that it be fitted into two side by side parallel slots (e.g. in XE50 series extrusions). All the roof members of an LFE series enclosure are suitable for this purpose. See Figure 6 for mounting options.
Insert an M6 T-nut into the extrusion slot at the approximate intended mounting position for the shelf.
Repeat in the parallel slot and again in the slots at the opposite end of shelf.
With two people, hold the shelf up to LFE frame.
Fit a small M6 washer to each of the four M6 x 40 mm bolts provided, followed by a large M6 washer, then pass the bolts (two in each end of the shelf) through the slots in the attachment bars and secure in the T-nuts fitted at step 10 as shown below. Do not fully tighten the bolts.
Slide shelf to desired position.
Tighten all four bolts.
There are a wide variety of options for mounting the shelf to the laminar flow enclosure frames. The cross bars of the LFE1220 and LFE1220W Enclosure Frames, which are highlighted in yellow below, are all compatible with the LFES1 shelf mounting hardware.
