okay, so no diffuser. wouldn't a pinhole greatly reduce the intensity of the light? right now we use mercury arc bulbs that are around 100W-300W and if we could stick with the same size bulb that would be ideal
we want to use it for UV-initiated polymerization so as collimated as possible to ensure that the intensity is uniform over the whole area we are polymerizing.
what about a diffuser? could i diffuse the light and then collimate it?
I need a help collimating light from a mercury arc bulb
i need the light to be collimated into a circular beam with a diameter of 5cm
i know that i need to use a fused silica lens because the wavelength of the light i need is in the 320nm range
buying a collimated beam arc lamp housing is...
