365nm UV LED Lights for Exposing Photo Polymer for Braille Signs
I'm wondering if these will work for exposing photo polymer for braille signs. The manufacturer recommends 350 nm.
We unfortunately do not have any data on photo polymers for this specific application, but do suspect that there may be some cross-compatibility between 350 nm and 365 nm.
I would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED bulbs are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund.
Any Ideas to temporarily mount 32" to a metal plate?
The one idea I can think of would be to see if a small section of the photopolymer cures effectively under a single row of the UV LED strip light. This of course would not be the same as the final installation, but may be helpful in getting an approximation on cure times and proof of concept.
Do you have a way off measuring Milli Watts/Square Meter Irradiance of the lights at 2" inches away?
Please see below for our irradiance charts.
Our closest measurement was from 12 inches, where we observed 228 µW/cm². This is equal to 0.228 mW/cm², or 2,280 W/m².
While we do not have any measurements at 2", one quick way to roughly estimate is to use the inverse square law, which states that the irradiance values increase by the square of the distance. Therefore, at 3" away (1/4 the distance), we would expect a 16-fold increase in the irradiance values.
