Light Intensity

Postby Bioprint » Fri Nov 08, 2019 8:58 am

Hi,

Someone knows how much is the light intensity in mW/cm2 of solus 3D proyector vivitek H1188 ?, because i checked the datasheet of vivitek H1188 and i didn't see nothing respect of the light intensity.

Thanks in advance :D .

Send Vivitek an email.

Maybe it can be calculated from the Lamp wattage and the total projection area?

You would need the distance from the bulb to the surface, along with the overall area to do a rough estimate of the mW/cm^2.

This can give you an idea of how to calculate it. The projector however uses a reflector, so that alters the calculation since it bounces back some of the indirect light back to the measurement point.
