Review of a Blu-ray Laser Module

Re: Review of a Blu-Ray Laser Module

I monitor the output with a silicon PV cell.
The black spaces I "saw" were well within the AF range, so response of the cell and the scope is not exceeded - not by a long shot.

Thanks for your help...

Re: Review of a Blu-Ray Laser Module

This is absolutely fascinating. It would be great to see a step-by-step of the method of building this (not wishing to take away from your little cottage industry, by the way!

We'll hopefully be seeing violet laser pointers very soon (which I'm sure, according to some manufacturers, will reach the moon etc)

You ***MUST NOT*** shine this in your eye - not even when the unit is below lasing threshold!!!
You will have bright afterimages that can persist for up to several DAYS...yes, I learned this the hard way

.

DOH!

We need a smiley that has an eye patch...

 

[The_LED_Museum]

Even below lasing threshold, the near-UV radiation is at almost a point source, and therefore, far brighter than the eye was designed to accomodate at these wavelengths.
Much brighter than any NUV LED you can find.
And yes, I'll reiterate: IT WAS BELOW LASING THRESHOLD!!! :green:

I'll agree - we need a graemlin that has an eye patch.

I'll go see if I can find one...BBS...nope, couldn't find one, so I made one:

 

[allthatwhichis]

... I made one:

NICE!!! Might want to make him look a lil "unhappy" about his situation...

or maybe

...

You know, I keep seeing these flashlight raffles... One of these UV "pens" would make a nice raffle.

 

[The_LED_Museum]

I just changed it from a "smiley" to a "frownie".

I DO believe you are correct - it would be an EXCELLENT raffle item !

ok, I just have to ask, what is up with "bash, toliaflex and torque?" only the other "T" seems to change. (and yes, I understand what BTTT originally means)

 

[The_LED_Museum]

The phrase was originally "BTTT (Bash Toliet Toliet Toliet)" but I was kindly asked to refrain from using the phrase on CPF.
So I had to come up with other terms besides "Toliet" to make the phrase work. :thumbsup:

 

[SenKat]

Uhm...What is a TOLIET ? I assumed you meant toilet - but I have learned not to assume too much anymore....

This may be a stupid question and NOT on topic... but why were you asked to refrain from using the phrase... "Toilet"? :ironic:

 

[The_LED_Museum]

I've misspelled that word since at least 1993.

To wit:

The top one is from an educational demo about AIDS that I wrote for the Commodore 64 computer in September 1993.
The bottom one is a screen for a BBS that I made around the same time.
Note the misspelled word on both of those screens.

Because some people who use CPF are rather sensitive about that particular fixture.

Honestly that makes me want to give up my CPF membership... As you say, it is a fixture, an appliance... It is probably cleaner than most... nevermind. It is not worth it. I find it offensive that you were asked to refrain from using the word. People need to worry about much more... sensitive matters than using "that particular fixture"'s name in a post on a public forum. I've seen worse words on an eBay auction. :sigh: What would that person use to describe... that fixture, to a child they were... training to use... that fixture? :duh2: We already have to sugarcoat what goes in there, now we need to sugarcoat the bowl also? Might as well start drinking daiquiries out of that fixture... :green:

I'm with allthat on this one... IMO this steps into political correctness and the overly sensitive feelings of people around the world nowadays. If you're ofended by the word "toilet" or "toliet" for reasons only personal, I have two words for you "grow up!"

Thanking your understanding;

I have sent this laser to a laser expert on the east coast of the United States - again. I also sent him my 100mW Blue DPSS Laser and my Yellow DPSS Laser.
As before, expect it and the other lasers to be gone for two to three weeks.

Two to three weeks... I'd die...

You have others to keep you occupied though right?

 

[The_LED_Museum]

I have my blue DPSS laser pointer, plus a plethora of red & green laser pointers & modules, so I'm certainly not SOL. :thumbsup:

 

[Heruursciences]

Oh NO!!! Try rapping the laser firmly on a hard counter top etc lens end down and see if the lens pops back in place. Failing that, send it back to me and i'll attempt to repair it for you.

BTW I have another unit on ebay currently also

 

[The_LED_Museum]

Hi Chris,

I tried rapping it firmly multiple times against a hard surface face-down and met with only partial success.
PM or email me your address and I'll get it sent your way pronto.
