Benm: When we speak of synthetic diamond, we speak of a mineral made of pure carbon, having chrystallographic, chemical and physical characteristics similar to those of the natural diamond; the difference is that the synthetic one is a man made mineral. First documented attempts to manufacture...

...the Grand Inquisitor....

pullbangdead: IMHO, I think that each single correction note, when performed under scientific purpose, must be witnessed with the examples and/or hypotized improvements; it is not sufficient to say "this interpolation is wrong" but it is important to show what kind of interpolation is right...

In order to supply scientific news to clear and avoid any doubt/misunderstanding, here are some info, taken from the book "The diamond today" (but this is the translation of the italian title of the book, so I don't know if this is the exact title in the english language), written by a famous...

And this is the Efficiency plot. (Updated 2009-11-09)

This is the Pi/Po plot. (Updated 2009-11-09)

After having seen the small size of the plot, I prefer to load one plot per answer. This is the Po plot. (Updated 2009-11-09)

Ok, here is the total comparison of all 8x and 12x actually I have recorded. All lasers have used 405-G-1 lenses with the exception of Larry, who used his special lens, which is the same of those used by Jay but fitted in a different nut. Sorry for the plot size. For a more accurate reading...

Ok Dave, give me half an hour and I'll summarize all 8x and now 12x I have.....:yh:

HIMNL9: well, everybody knows the Ohm law V = RI, so IMO your supposition is right. Unfortunately only three members, of the eighteen "declared" owners of a 8x BR, have been able till to-day to supply PIV data relevant to their products (you can easily check it giving a look to #2, #3 and #4 of...

IgorT: #529: Wow, Igor, beautiful work and plots!:beer: It looks that these diodes show a wider Pi/Po (efficiency) range with respect of the two BDR-203 diodes (Dave and mine ones) shown in my datasheets... I have replotted these data putting into evidence the 1600mW Pi line (but recorded with...

Hi realista, I was giving a quick look on the various Forum threads, when I have seen your question. So I suddenly took a small tripod (one of those sold by DX) and I fixed the IgorT PHR (equipped with a 405-G-1) at a distance of 4 inches from a sheet of white paper, as per the following pict...

Wow, Jay, your solution to use a standard Aixiz spring to hold the lens in place is simply genial! :D As you know, the "compression type" springs are designed to work till to pack, so if the free length for the spring inside the modified lens nut is 3.0 mm. (just to be sure) or greater, no need...

After a casual test performed in another thread of this Forum, I was curious to take a picture of three different beams refracted in the water contained in a glass square vessel. So this is the picture: The beams enter laterally from the right, and the lasers are 1 meter far and well below...

Daguin and dieselmarine: Datasheet updated.

rangedunits: Thank you. He he, Traveller reviews have really increased the difficulties to make a valuable review for all members that aren't poets/professional writers..... :D Olivia: Oh, wow! It is always pleasant for an old man to receive congrats from a gentle girl! :yh:

mfo: mmm, I used the wrong word: change reflection with refraction! Sure, this aspect must be always taken into account; using this pyrex container (with the rounded lower edges) it is possible to see a pale horizontal reflection inside the water, while the laser is clearly sloped and at a lower...

Another simple way to take a beam shot is to use a glass container filled with water....you can make also some interesting reflection effects...

To all LPF friends! At the end of the last week I had two days with "problems" (read disconnection :yabbmad:) on the phone line.... You can imagine my surprise when returning back in the Forum I have found my rep jumped to nine!:angel: What can I say? A really warm thank you to all members...

8x BR Owners datasheet updated.
