The blue semiconductor laser emitters’ Blu-Ray disk’s light sources work with a very low output and actually emit violet light at 405 nm. LIMO Lissotschenko Mikrooptik GmbH has developed micro-optics for true blue single-emitter diode lasers.

The technology focuses the beam with precision on an area measuring ~40 × 40 µm. Micro-optics technology is suited for pumping solid-state crystals and for fiber coupling.

The low-cost technology requires only one micro-optics device to focus the blue laser. Two versions are available for diode lasers with or without housing.

madmacmo;

Refractive technology can present some unique solutions

to our collimation of laser diodes.

Cost of this solution is the question now.

That is one crazy cool looking lens. Exactly how does it fix the wide beam of a 445?

Each side looks like a "cylindrical" lens kinda, and with the sides being 90* rotated. I'm guessing one side takes care of one axis, and the other side corrects the other axis.

Probably have to get them custom made to fit the output characteristics of a specific diode. I'm not enough of a nerd to know if, generally speaking, single modes have approximately the same divergence characteristics.
