Finally some Opto 155mW Pics

Alright I've been pretty busy but I thought Id throw up a few pics of my newest laser, the Optotronics 150mW Green ( tested at 155mW ). Now my pictures aren't like emc2's because one, Im not much of a photographer and two I use a 5mp sony point and shoot lol. So Im not counting on anyone using these as backgrounds.

thanks thanks thanks thanks thanks thanks
really

Just be careful with that if you don't have eye protection! I don't necessarily know the effects of looking at it on a surface and burning but reflection and you're done

Ya Im very careful indoors. I have a pair of laser shades used for burning and up close playing, thanks to thug life in the buy, sell, trade forum.

its too bad my 150 opto looked nothing like that. Mine couldn't even light a match with brand new lithium ion batteries. My lasers never turn out right.

ALSO I could barely see the beam at night.

What did Jack specify the average power output to be? There was a piece of paper in my box that said it had an average of 155mW.

I drained some juice from my lithiums before using them in the opto because they have been known to push 1.7 or even 1.8 volts, which can damage your laser in minutes or instantly.

Ill take some night shots later if I can, but the beam is amazing at night. Even under streetlights it just glows. Im up in michigan, we usually have high humidity which I imaging helps with night time visability.

Lastly did you contact about about your issues?

Ive found that batteries at around 1.4 to 1.5 volts gives the optimum brightness to heat related issues. Fresh lithiums are noticably less bright that partially drained coppertops. Dont ask me why but My opto 178mw pen likes batteries at around 1.4 volts or less. Trust me Lithiums are not your friend on this setup

mine is rated @ 164mW average, and WOW. just got it today and i already have my friend saving to get one... must have been after seeing my crappy one compared to this amazing unit.
very nice laser and worth every bit it costs

Totally agree. Lithiums for one reason or another don't work well with this laser. Just grab some rechargeables (which gives plenty brightness) and call it a day. Not to mention you won't have to worry about possible long term damage.

BATTERY FACTS

Can NiMH batteries be substituted for alkaline batteries even though they are only 1.2 volts?

Yes, for most high drain electronic applications NiMH batteries are ideal substitutes and you needn't worry about the apparent voltage differences. Even though alkaline batteries are rated at a nominal 1.5 volts, they only deliver 1.5 volts when they are fully charged. As they begin to discharge the voltage of alkaline batteries continuously drops. In fact, over the course of their discharge, alkaline batteries actually average about 1.2 volts. That's very close to the 1.2 volts of a NiMH battery. The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. NiMH batteries stay at about 1.2 volts for most of their discharge cycle.

There are a couple of cases where their actual voltage difference may be important to you. In the case of a device like a radio, where a higher voltage can mean a stronger signal, a fresh alkaline battery may be more desirable - but more expensive - than a rechargeable NiMH battery. This is also true for a flashlight, which will be brighter with the initial higher voltage of alkaline cells. This minor difference may not be important to you and is probably offset by the much lower cost of operating NiMH batteries. And keep in mind that the alkaline battery only has a higher voltage when it is fully charged. Once it gets to 50% capacity or less, it will be delivering a lower voltage than a NiMH battery.

The one time when the voltage difference of the two is important would be in the case of a device that checks the voltage of a battery to estimate the amount of charge left on the battery. Because the voltage of an alkaline battery drops at a very predictable rate it's possible to estimate the amount of capacity left in an alkaline battery based solely on its voltage. (1.5 volts - fully charged, 1.25 volts - 50% charged, 1.0 volts - almost fully discharged). But a NiMH (or NiCd) battery stays at about 1.2 volts until it is nearly completely discharged. This makes it almost impossible to know the amount of capacity left based on its voltage alone. When a device that's using NiMH batteries indicates the battery is low, it's time to change the batteries now!

My lithium's seem to work great. I've used them with great results in my past 3 lasers a CNI 120, black chrome 150mW, and 55mW ebayzer. They seem to give excellent power and last for a long time.

Im wasnt saying they dont work great with other lasers all I was saying is they do not work with my Opto 178mw pen.

Alright dude....that looks like a 150! Nice photos and I am glad you are enjoying the laser.
