I have 8 no. DO-41 sized diodes in a row like so (representative image):-
I'm hoping to place them adjacent to each other on a 2.54mm pitched proto board. They're glass cased and I need to totally screen them from all light. They can't be screened via the overall circuit's enclosure as it's translucent.
It's a sign of good quality in that they actually manage to butt up against each other on a 2.54mm pitch, despite the data sheet suggesting they might not. However this means that they cannot be heat shrink covered, due to lack of space. So are there any alternatives to screening them from all light? Remember that a proto board will have holes beneath the diodes. The proto board is an Arduino shield of 80mm x 60mm size so I'm hoping to keep it tight.
For interest, this is the spec. for a DO-41 package:-
