High Efficiency Mounted Collimating Glass Lens - Machined

The lens carrier of these lenses has been machined with a taper so that it can be used with some diode holders where otherwise the lens cannot be screwed close enough to the laser diode to focus at short distances.

This single element lens gives around 15-20% increase in output compared with the 3-element lenses with a small reduction in beam quality. Machined version.
