Guest Hypnotic Posted August 11, 2009 Share Posted August 11, 2009 Am gasit recent pe ebay un tip care vinde diode laser de diverse puteri. Cele care mi-au atras atentia sunt de blu-ray (cica) si vin in 2 modele: 150 mW - 34 $ http://cgi.ebay.com/150mW-405nm-Blue-Violet-blu-ray-Laser-Diode-in-Module_W0QQitemZ180395027285QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2a0061ab55&_trksid=p3911.c0.m14 200 mW - 52 $ cu transport moca. http://cgi.ebay.com/200mW-405nm-Blue-Violet-blu-ray-Laser-Diode-in-Module_W0QQitemZ170369649253QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item27aad28a65&_trksid=p3911.c0.m14 Ar mai fi inca una de 300 mW (rosu) la 36 $. http://cgi.ebay.com/300mW-650nm-Red-Burning-Laser-Diode-Module-w-Driver-Kit_W0QQitemZ170370214119QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item27aadb28e7&_trksid=p3911.c0.m14 Voi care credeti ca merita? Este posibil sa fie aceeasi dioda blu ray, cu driver schimbat? Multumesc! Link to comment
Laci Posted August 11, 2009 Share Posted August 11, 2009 Eu asi lua pe ala de 300mW rosu, cele albastre se pare ca sunt dintr-o unitate blue ray: "Pulled from a new (never used) high powered blu-ray burner".Ca driver ai acolo un LM317 cu care reglezi tensiunea. Link to comment
cotocu Posted August 11, 2009 Share Posted August 11, 2009 @Hypnotic,Salve,user-ul bandtled de pe Ebay este unul cunoscut si serios.Cea ce scrie el pe Ebay(150/200mW) este puterea maxima disipata.....dupa un test mai mare de cca 5 s puterea de iesire va fi de "0 mW"!!!In practica stam cam asa:la un curent de 95mA(pt dioda de 150mW) avem cca 75mW( dar asta cu un sistem optic bun...de ex. Lens 27..).Cea de 200mW functioneaza fara probleme la 100mW.Comanda este facuta pe LM317...deci este TTL.405nm nu sunt 473nm!!!....deci este violet.Pt mai multe info:http://www.sony.net/Products/SC-HP/pro/laser_diode/blu_ray.htmlPentru rosu, este o dioda LG de la un DVD RW cu un sistem de lentile(china).O zi buna!

Guest Hypnotic Posted August 12, 2009 Share Posted August 12, 2009 Multumesc de raspunsuri...mai am o intrebare: Care are putere de "ardere" mai mare? L-am intrebat pe vanzator si mi-a raspuns: Well, I'd say the red can burn more. But they each have their own special talents. The BR can light up glow-in-the-dark material and it can really be felt like a stinging burn on the skin. But you won't feel the red on your skin, but it can burn objects very quick.Aici nu inteleg ceva...daca rosul arde mai repede obiectele, de ce nu se simte pe piele? Link to comment
Laci Posted August 12, 2009 Share Posted August 12, 2009 parerea mea este ca din cauza ca cel albastru este aproape de UV, rosul cred ca patrunde mai adanc in tesut, oricum nu-i bine sa experimentezi pe oameni/animale. Link to comment
