Hey all I have a host where I'm noticing the threads are getting a bit rough and scratchy. I know that it's common that people oil their threads to make them smooth, but I've never done that before. I was wondering if anyone can suggest how I would go about doing it and what kind of oil I need...

Just thought this little gem was worth a share. There's an ad at the top of pages that often suggests random laser related searches (usually super n00b questions) One day this popped up. Needless to say, DON'T do this...! :ROFLMAO:

Ok so, I got a question. Obviously you can extract red diodes from various CD/DVD RW drives. Do these diodes vary greatly depending on what drive you harvest them from whether in power, wavelength, efficiency, lifetime..etc?

Hey all. So I've was having an interesting conversation with another member about the effects of different wavelengths regarding the accuracy of the readings when measuring a laser's optical power. I found it very odd because I know LaserBees for example, are rated for broadband coverage of...

Hey all, I was trying to learn a little bit more about laser lenses to find out their swapability. I see a lot of lenses are listed in the "M9x0.5mm" form factor and similar. I was just wondering what this means and if I can find out the diameter of the whole threaded brass part from this to...

It's just past 12:00 here, but wherever you happen to be, happy newish year, happy new decade you guys! 🎆🎆🎇✨🎆🎇✨🎆 I'm both very excited and terrified what this new decade will bring.

I'm in need of an LPM and I am looking for heads like the 20C-A-1-Y to hopefully build one or if someone has an Ophir based LPM that would be awesome. Many thanks.

I've been experimenting with some cheap Chinese 532nm pointers and I want figure out the best way to clean the lenses. I know of G2, 3-Element, G7 lenses like the ones used in quality lasers, but I don't know what kind these cheapos have. I assume some kind of basic plastic collaminating lens...

Hey guys, still trying to find the perfect LPM. I know LaserBees have been set with OEM Ophir heads like the 20C. The thing is, the Ophirs have a 4 pin output befitting a Molex connector for example. But, the sensors that plug into the LaserBee seems to have a headphone jack AUX cable type...

Hello everyone. I'm purchasing a new laser at 1.6W that takes x2 16340 batteries. I know a bit about 18650s but not so much about the 16340s. I've been looking for some very good batteries like NiteCore, AW, Efest..etc. They all seem very similar but what I'm noticing is the different...

Hello everyone. So this will be my first "real" post after weeks of reading and searching stuff around the site. :) I've also decided on my first, also "real" laser. It's 445nm @1.6W and takes two 16340 batteries. Now I know all the names for these kinds of batteries get thrown around a lot...

Being new, as people stress in the stickies, I use the search bar almost religiously before asking a question that has been covered before. And also to do extensive research. That's why it really irritates me when I try to search for something specific and get screwed over by "The following...

My name is Snecho and I'm from Earth, Milky Way Galaxy. I am 19 years old going on 20. I've been reading through all the Rules and Stickies for the past couple of days and decided to try write a bit about myself. A little backstory here, I've been part of a local engineering club called a...
