Projector wavelength spectrum range


I want to determine the Wavelength spectrum of the projector used to photo-cure resin. I saw that the tech spec page lists a 405 nm wavelength but I am curious if there is more width to the spectrum band. Does anyone know if the projector light is filtered and if it is what range of spectrum is able to pass through?


Here you go:

More information:


We’ve tested the Ember’s optical engine with a 385NM light source and experienced very little loss through the whole system. The entire spectrum of the 405NM LED should pass through virtually unchanged.


Awesome! Thank you!
