I have a graph of the relative radiance spectrum of a UV Lamp as shown in the graph. I particularly need the irradiance at a particular distance "z" and area "A" spectrum. Any thoughts on how to go from this graph to the other?
Hello,
When you say "at a particular distance "z"", do you mean at a particular distance from the source? If so, is the media where the light is transmitted transparent (to those wavelengths)? What type of light source? How is the optical pathway?
What do you mean area? the area where the light is going to be irradiated?
What about the used detection unit?
For the lower range even air is not transparent and solarisation of the windows can take place.
Without knowing the exact profile and the output of the light source even in normal range the intensity in W/m² is difficult to obtain, see publication.
Article About the possibility of calibrating optical detectors by so...
Alonso, Ill try to be more specific. By "z" I mean the distance from the source to the device (which is flat). The device is a diamond based MSM interdigitated structure therefore has an active area "A". The lamp is a Deuterium UV lamp which is not working in vacuum therefore some photons (those with the highest energy) might be absorbed and produce ozone. Regarding the pathway the lamp is going to be placed as perpendicular as possible to the device.
Michael, the detection unit is not specified. I assume is (W/sr.m2) which is the units for radiance. What publication do you mean?
