A typical flash lamp 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.
The Solution: NovaCentrix’ Photonic Curing Filter Set
- • 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
