| These diodes are a deep violet (near-UV). Commonly used in Blu-ray devices (including game consoles and Blu-ray recorders), these diodes range in power from 100mW up to 500mW. These diodes have a very high Vdrop (approaching 6V) at higher current levels; consequently, a driver that can deliver this additional forward voltage must be used. | These diodes are a deep violet (near-UV).

| All diodes listed are single-mode, single-emitter. It is recommended to use AR-coated glass optics at output powers upwards of 200mW to prevent the lens/lens housing from melting and possibly damaging the diode. | All diodes listed are single-mode, single-emitter.

| This is a single-mode diode. It has a nice small beam with a good deep(ish) red color. The down side is they are expensive and don't make much over 150mw. If they could get powers higher these would be the diode to have. It has a small emitter, and makes a nice small beam. | This is a single-mode diode.
