Air Vents
A series of vent holes are located around the perimeter of the LM4X LED module section. This allows transfer
from the heat sink to help to cool the LEDs as air is drawn in from the cooling fans or cooling air supply. Keep
these vent holes clear to avoid the unit from overheating.
Caution:
Do not cover vent holes. Covering the vent holes will cause the unit to overheat and over-temp
protection circuit will engage.
Filter and Filter Holder Assembly
The bandpass filter is a glass filter on the LED module is used to reject wavelengths outside of the specified
LED output spectrum to produce a narrow band output.
The bandpass filter is held in place with a set screw and retaining ring. The retaining ring can be removed
or installed using a 0.050” hex wrench. Replacement filters can be purchased as spares or replacements for
a broken filter. Take precautions when handling the LED module as to avoid damaging the filter. The
thickness of this filter is 1mm so an impact to it could crack it.
