Hi IRstuff,
I understand steradians or sr's, what typically would a highly polished, non diffuse exit surface give - this is a non optical expert asking.
Regards to you

Hi Brian,
You are right of course, always keep it simple if you can. Unfortunately I need to cover the LEDS because of robustness, security and aesthetics reasons. The light guide will probably be acrylic doped in a very dark red to act as a colour filter. We have done this before, albeit in...
Hi,
I have posted this on the optical engineering and electrical/electronics forums. Please forgive me, but this is possibly a diverse question and people may have the answer for me in all or one of the forums.
I am designing a hand held infra red transmitter, I need to produce a light guide...
Hi,
I have posted this on the optical engineering forum, but I realise that peole may had this problem or know the answer on this forum.
I am designing a hand held infra red transmitter, I need to produce a light guide to get the infra red out of the case into the environment, so that the...
Hi,
I am designing a hand held infra red transmitter, I need to produce a light guide to get the infra red out of the case into the environment, so that the infra red receiver can pick up the signal. I am fairly happy about the coupling of the infra red led's into the light guide and I intend...
This is a minefield and we get stuck with the same problem. We manufacture electrical control panels and we refer to BS7671 for UK installations and we use the appropriate international connection symbols and connection circuit diagrams in the written instructions. We also explain the correct...
I would have created the outside or solid shape first. I would then have added all the external features that are directly related to or are a part of the finished wall thickness. I would then have shelled the inside to the correct wall thickness, and then added all internal and external...
In electrical items, the critical components are those that their failure could lead to a breach of electrical safety. Not enough info. but in a computer system it will be a power supply and in the power supplies it will be usually, Mains fuses, fuse holders, IEC mains connectors, components on...
Hi,
Inventor seems to be very graphic card specific. I had recently a case where I was using an approved graphic card and driver by Autodesk for Inventor, and was seeing strange random things in the .IDW files. I upgraded the driver to the latest non-approved driver and it now works perfectly...
I haven't got MDT5 yet, but in MDT4 I only know of two ways.
1) place the base view you want to take the section view from outside the paper area, so therefore that view is hidden when you plot and the section view updates as you make changes.
2) use the "amviewout" command to capture...
I have exported STL files out of MDT 4 several times. I have found that you can only export a single part at a time, clicking on an assembly will get you nowhere fast. I don't do assemblies, I design complex single parts for injection moulding, so for me it's not a problem. I generally use the...
Seeing as you are already an AutoCAD user have you looked at Mechanical Desktop or Inventor, both AutoDesk products. The big advantage of Mechanical Desktop to you, would be the easy migration of your legacy data.
