Hi to all.
This is my first complete and almost well done review for a laser build, so be nice please
Starring two awesome items:
- The DTR 16X BDR-209 Diode In Copper Module With Driver @ 700 mA and 405-G-2 Glass Lens;
- The Sinner's Cypreus II copper host.
For this build I have used three new special guests:
- A new digital WELLER WSD81 SE 80W soldering station;
- A 7W Laserbee power meter with Ophir head;
- An handmade reamer.
So, let's start!
The soldering station:
The 7W Laserbee:
The handmade reamer:
This item was built usying a japanese white marker and a extra-fine sandpaper.
I put also some pre-lim paste over the sandpaper, a very gently surface cleaner.
The total diameter is about 11.5 mm, but I can easily vary it adding more coils of sandpaper.
I use this reamer to create a very smooth mirror surface into the heatsink hole,
to have a perfect contact between the parts.
The violet diode and the 0,05mm Indium foil:
All the needed parts:
Diode module gently scrubbed with extra-fine sandpaper:
All the contact parts were extra-cleaned with the best cleaning liquid fluid available today in the market:
Diode with Indium foil wrapped around, ready to be inserted into the heatsink:
Diode inserted with good pressure into heatsink.
No need to use the set screw.
Crown pressed into focus ring with the help of a vice:
Soldering and connect the inside wires:
In order to avoid any possible short, I have added a soft piece of rubber between the screws:
Assembled heatsink:
The final product:
Cypreus II on Manfrotto minipod:
The beamshot:
The violet beam is very difficult to capture with a camera, especially to obtain the right colours.
This shot looks like a blue laser, but really is much more violet.
I was forced to use a 15 sec long exposure to have a decent amount of light.
The fluorescence ignition:
Those air-conditioner remote control buttons seems to be backlighted, but they are off!
This is a pretty fast reaction of fluorescent materials when affected by a violet frequency.
The performance graph:
What an awesome diode! It is very stable, and tend to slightly increase output in the time!
I have limited the test to 90 seconds, but with Cypreus II surely I will have a longer duty cycle.
After 90 sec the copper become slightly warm, so Indium foil and copper parts are doing their dirty work!
Finally, the video:
The host was placed at about 3.5 meters from the mouse pad (yes, was a
professional mouse pad ... :yabbem
.
The surface began to smoke immediately! Also the match light at once.
The dot is so powerful, tiny and precise that ignite light wood pretty fast.
Goggles is a must, this is really a dangerous laser !
Conclusions: this is a masterpiece, powerful, precise, rock solid and made with a high craftsmanship.
I wish to thanks a lot two guys that allowed the creation of this project: DTR and Sinner.
See ya soon for my next reviews .. stay tuned! :beer:
