Updated my UV-led test method (=final), tested a Luminus SST-10 365nm led (and some others)

[exekutive]

I have been having trouble with getting parcels from China lately. Postal workers probably dumped them in the river during the strike action last winter. I had to reorder the digital UV sensor, and 3W UV LED because they never came. The ZWB2 filter came, but it’s absolute shite. It lets through lots of visible light.

My second order of 5mm UV LEDs came (1st order never made it). I posted an analysis of them and an instructional how-to about measuring light wavelength here:

Testing your UV LEDs

Let’s say you need an LED or a laser of a particular wavelength (color). Here is a very easy way to test your light source to see if it is actually what it claims to be. You can set it up in about 15 minutes using stuff you probably have around the house. For this example, I’ll use some inexpensive 5mm UV LEDs purchased on eBay. The description says they have a wavelength of 365nm. (useful for curing photosensitive polymers for bonding, etching etc.). [image] So to test these LEDs, we can ex…
