A typical flashlamp emission spectrum is broadband and includes UV, visible, and NIR emission (~250nm –1500nm). For some applications, it is desirable to remove portions of the spectrum.
A temperature-sensitive substrate may absorb a portion of the beam – even if it is nominally transparent
Experimenting in different spectral bands is expensive, with custom high-power filters costing thousands of dollars per filter.
|Removes portion of beam preferentially absorbed by the substrate|
|Level of curing can be increased without damage|
|Convenient, easy to use, cost-effective processing in multiple spectral bands with high-quality, dichroic OD4 filters rated for high power|
|Recessed within solid aluminum cover plate|
|Operating window can increase dramatically – within same platform|
|Steel retaining ring and recessed optics – insure minimal contact with filter surfaces|
|Filter surface faces towards inside of PulseForge tool – not the sample – so the filter stays clean|
