Optowell Red VCSELs
Optowell
Visible Red VCSELs have a wavelength of 670nm, stable output power of 1mW
at a maximum operating temperature of 50° C, circular beam and power
consumption 10x lower than equivalent laser diodes making them suitable
for various commercial applications where they could be used to replace
existing red laser diodes.
