Default Reflections

473 and 532 battle it out


Add some red and purple into the mix


All DPSS


All at once


Purple blue and green


These were all done with my new 35mm f/1.8, it's better quality than the other lens and a perfect focal length for a lot of what I do. 445 just spoils most of the pics with a blue wash and my Rigel doesn't lase yellow at all anymore unless it's really warm.

Great! Wish I could do that!

I presume the mirrors are front surface mirrors. Are you using any fog?

When you say "purple" is that 405nm? What power are the lasers? [sorry for all the questions!]

405 is purple - it's just a newwish pen so power I have no idea, but the beam is visible in the dark. I used incense just to purify the beams a bit. Without it they appear more "gritty" - I'm sure you've experienced the same. the green is a 100mW portable, the red is a 30mW portable, the yellow is a highly temperamental ~10mW portable, the 473 blue is a lab ~150mW, bought it recently for 100, unbelievable price for a high quality DPSS that can be left on for hours at a time.

they are just mirrors for doing makeup or shaving etc, few quid off the 'net.

Just need a decent yellow now!

Was the 473 blue second hand or would I also be able to buy one for 100 [With labby do you do a special power supply too?]

Normal mirrors - wow - I just assumed you would have got a shadow beam showing where it reflected off the glass.

Yellow - sooo expensive

Default Re: Reflections

I bought the 473 from one of our fellow members:
http://laserpointerforums.com/f39/fs...p-p-91105.html

I don't think you'd often find a 473 for 100, even a lab. Lab 473s do seem to be surprisingly cheap sometimes but I've only ever really seen the cheaper ones in the tens of milliwatts range. That's why I bit twirly's hand off when I saw that thread. It's missing the cover from the driver and is an older model so it needs a separate 5VDC power supply for modulation (which I fashioned from an old ATX PC power supply by crossing some wires - literally). It's still across the room from me now shining away since I started using at the beginning of the night two hours ago, stable as a rock. The normal power supply and laser head are just different components but they're part of the package that you'd call a lab laser really.

Yellows are ridiculously expensive, yes. Which is why I'm having a very hard time about buying a more powerful one as I find it hard to part with that kind of money.

Not sure what you mean on the mirrors - they reflect a laser beam in the same way it reflects all other forms of light - back at an angle that it hit the mirror.

It was based on normal mirros being 2nd surface, like this:

Just seen your photos again - I still can't believe how well your 405nm has photographed. I have so much trouble with my cameras. Maybe it's the due to my 405nm being a cheap ebay pen.

My 405 is just a "cheap" ebay/newwish pen, like a few of my others but they're all soldiers - I've ran them for over an hour constantly before without problems. The 405 I think is quite powerful as the beam is visible even in a lit room if you get the angle right.
