As described in my intro post ("Hello from Massachusetts"), I'm interested in doing laser-stimulated fluorescence photography and I'm trying to assemble a setup.
My requirements are:
- Battery-powered 405nm laser pointer (or module, if a pointer is impractical to attach the lens to) in the 150-300mW range.
- Powell lens with a 30 degree fan angle attached to the above laser. Somehow.
- [ETA] As little fabrication as possible since I live in a small studio apartment and even drilling stuff is difficult with no place to put a workbench.
Also desireable but not strictly necessary:
- A way to decrease the beam power.
The problem is that I have no experience with lasers really, so I am not sure how one goes about attaching the lens to the laser, especially an odd-looking thing like a Powell lens. ThorLabs has some nice Powell lenses and I've found many other sellers, so obtaining the lens doesn't look hard. For the laser, portability is very important (this is likely to be used to photograph graffiti in abandoned houses and the like, which may require a hike) so I need things to be light and self-contained as much as possible. So I think a laser pointer is preferable, and I can carry the batteries separately for safety.
I haven't settled on a pointer yet but I was thinking strongly of the JetLasers PL-E Pro 405nm Violet Laser at 300mW, or possibly the Mini at 150mW (but the Pro seems to allow power adjustment?). And probably the Thorlabs 30 degree Powell lens if I can figure out how to attach it! All help much appreciated.
