Customer Reviews
I have always used laser pointers in my classroom. They're such an efficient teaching tool to direct attention. I'm very pleased and excited about using this particular laser pointer this school year. The color of the laser is fabulous! It demands attention because of the strong, unusual color. The quality of this laser pointer is very nice, as well. It is sturdy and comfortable to hold. Shipping was quick, which is much appreciated.
I used this laser pointer when I was giving a presentation to some older professors. The younger ones could see it fine, but the older guys claimed they couldn't see the light. However, as physics professors, they knew exactly why. One of them he said his minimum wavelength to see was around 425nm, but that he hadn't tested it for a while and it might have gone up. Of course, as a physicist this is just the sort of thing he would know. As this laser outputs at 405 nm, it could be difficult for older people to see the light.
Other than that, it worked great and seemed well made. However, if you have to do a presentation to someone older than 65, I would recommend a green one instead.
