Thanks for the input. I'll look into the mini! Already have a pair of nice safety goggles too :) I was worried that the DPSS lasers would have less longevity and efficiency. Is this not the case? Also, any thoughts on the duty cycle? I saw Sanwu had a 45 sec duty cycle on their 70 mW...

I'm thinking about buying this laser for some general star gazing, but I have a few questions about the options: 1. Is the beam expander worth it? Does it make the beam visibility significantly greater? 2. Manual or Code lock? What are the pros/cons? 3. What is the duty cycle of this laser...

Thanks. I will likely go for a 50-70 mW green laser. The main purpose will be for star gazing and observing the beam or dot from a distance. A few more questions: 1. Is there any noticeable difference between 532nm and 520nm? 2. What company is recommend for a 50-70mW green laser...

Hey thanks for the responses. To clarify, I'm aware of the FDA regulations on 5 mW laser pointers. However this based on direct expsure to the eye. I'm strictly referring to the ambient, reflected light due to the laser speckle.

Thanks for the quick response. :) Two follow up questions: 1. What are the upper limits before safety starts becoming a serious concern (like when does looking at the dot from about a foot away become dangerous)? 2. Even with a focusing lens I couldn't burn some kindling below 1-2W?

Hello all, I'm looking to purchase a new laser pointer to use when camping. I'd like something with high beam visibility during the day, that doesn't require safety goggles to look at the beam (or dot from at least 100m away) and the capability to start a campfire in under a minute (with a...

I went with the ebay link. Thats the same model I had from Olike and I liked it. I still have a few extra caps to play with too. Thanks for all the help.

I was actually planning on using a lot of mirrors with this pen... I was going to have them secured in place so that the laser follows a predesigned pattern though. Ehhh... still not sure which method to use. I want a working laser, a safe laser, and a bright laser. if you can confidently...

And if I want to use it without safety goggles or taking extreme precautions, where can I get a "safe" laser that is actually under 5mw? Thanks for the help so far btw

How bad is the IR leak really? I plan on just viewing the beam from close range on the wall.

So can I be confident buying one from Ebay then? I just want a bright laser pen, that hopefully isn't leaking IR.

I got one of these from O-like a while back saying it was 50mw, but I didn't notice much difference in my 50mw vs my friends 5mw from ebay. Mine recently broke (I would shake it a bunch, which led to the crystal becoming unaligned...i think). I want to get a replacement and I was wondering if...

I understand that I should be careful, and I always try to be. But, I don't want to have to wear safety goggles, as the laser is mainly just to show off to friends. I have a diffraction cap that makes a large array of dots that I project on my ceiling, and after a while I hurts my eyes to...

I've been playing around with my new 150mw green laser pointer and found my eyes hurting a little afterward (just feeling slightly heavy and tired). I believe its 150mw, from O-like. I know not to shine it in anyones eyes, but I'm wondering how dangerous it is to look at the beam, dot, and to...

I think I'm going to just get the 50mW one from o-like, but I can't seem to pay with mastercard. Doesn't give me the paypal option or mastercard option. only accepting visa. Is there another site that might sell this same model more reliably, or possibly a strong mW version?
