This simple means it’s a 0° not a 45° or brewster angled filter, of course if light hits more angled it will lose some blocking
probably best here to use LEDs with a high dome not domeless ones
Not sure if you can source ZWB1 filters easily like ZWB2
The ones I’ve tested pass too much visible. Sadly… I use the narrow beam (high dome) LEDs but they really don’t work with the dichroic filters I’ve tried.
Yes, simple to order ZWB1 but we don’t use them other than for photography (reduces the blue/purple bleed you see in many fluorescent mineral photos). I’ve got a few ZWB1 filters, and ZWB3 filters also that we are testing for SW 254nm (Hoya is discontinuing the manufacture of u-325c bandpass filter glass - a big problem for us).
Problem with the ZWB3 is that it solarizes over 50% in under 100 hours - not suitable for shortwave lights.
Just an FYI - way overpriced. You can get them on Aliexpress for less than $2.00, $0.50 in small qty. Special order, but they seem to be able to scrounge them up.
Those would be so neat to play with. But $4.7k probably not economical
FWIW - back when there was only one (cheap) source for the 405nm diodes I tore one out of a playstation. Built a mineral light - the very energetic beam was amazing, in spite of the purple light. Did things to minerals we didn’t expect.
Wonder if there’s some commercial application for this where we could do the same (rip the diode out).
Will Google…
Just gotta ask the ones on Aliexpress that look like manufacturers (hard to sort from all the resellers). Eventually you’ll find one who has them. Lots of companies making these it seems.
You mentioned specific prices, are they from a specific seller that you or someone you know bought from? Which one? Are you confident what you received was a ZWB1 filter, not ZWB2?
Sorry, haven’t bought filters in over a year. Last time I bought I purchased 500 pcs of ZWB2 for $0.50/ea and 10ea ZWB1 for around $2 - but that’s a long time ago. Suggest you contact several of the manufacturers - I’m sure they will give you a good quote.
Mark, that looks awesome! It looks like it’s only 1.5 amp though. I was reading back through the thread and it looked like you want the 4.5 amp buck driver though, right?
Hey Mark, thanks again. I just ordered it. Really excited to get this thing…
Really glad I joined this forum. Everyone I know can’t understand why I’m “obsessed” with flashlights and now I know I’m not alone I told my buddy that I ordered the Imalent MS18 and he said “Why do you need that? Are you trying to find something on the ground at night from really far away?”
I have the feeling that there are others on this forum who get excited when they tear the box open and pull out the new flashlight
