420nm Lasers

What are 420nm Lasers?

420nm blue laser diodes are available with both single-mode and multi-mode beam profiles. They have either free space or fiber coupled outputs.

The diode laser packages are ideal for OEM applications, and laser modules are available for either OEM or plug and play applications.
