5.0 out of 5 stars Zooinc Laser: 5mW at 532nm (green spectrum region), 20 Mar 2010
This class IIIb product, is very powerful and consistent. It consumes 5mW of energy and emits coherent light of wavelength 532nm. I am very happy with it. It's a little too powerful for presentations, as in a dark ambiance its light-point is very bright to let anyone concentrate on the slides(!). I went for this laser in order to use it for some experiments (diffraction, diffusion, Young's experiment etc.)

In short, brilliant laser; powerful to the border the law would allow in most countries.

5.0 out of 5 stars Hoya 72mm Pro1 Digital Circular PL Filter (Purchased on 18/09/2009), 19 Oct 2009
I got this filter for my Nikon D300. I mainly utilize this filter for landscapes (& panoramas) to increase contrast and color vibrancy and to cut off reflections from non-metallic surfaces. So far, it's been a wonderful asset. Glass quality is brilliant, does not stain from water droplets, does not get scratched from dust. The only backside of this filter, which was expected, is that one looses two thirds of a stop when mounted.
