Photonic Curing
Photonic Curing is the high-temperature thermal processing of a thin film using pulsed light from a flashlamp. When this transient processing is done on a low-temperature substrate such as plastic, paper or glass it is possible to attain a significantly higher temperature than the substrate can ordinarily withstand under an equilibrium heating source such as an oven.

Photonic Curing Filter Set
NovaCentrix Quality, Flexibility & Integration
NovaCentrix’ family of in-line filters for spectral photonic curing are compatible with all PulseForge R&D platforms.
Direct Subsitution
Filters integrated into beveled aluminum plate can be directly substituted for the quartz window of any PulseForge R&D system
Full Bolometer Integration
Full retention of PulseForge NIST-traceable integrated bolometer to quantitatively measure energy emitted – as each filter is located such that bolometry can be performed directly through the filter!
Direct SimPulse Integration
Energy measurement from the bolometry can be directly entered into NovaCentrix’ SimPulse® photonic curing simulation software to estimate the temperature in a user-defined thin film stack as a function of depth and time – another NovaCentrix first!
The Challenge
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.
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 |
| Four 50mm diameter filters: | – Fused silica blank (full-spectrum processing) – Visible block filter (475-750nm removed) – Visible pass filter (400-750nm pass) – NIR pass filter (700nm long pass filter) |
| Sturdy pelican case for storage and transport | Included |
| Lens wipes | Included |
