| Ordering number : EN5859A DL-3148-023 Red Laser Diode DL-3148-023 AlGaInP Laser Diode Overview DL-3148-023 is 635 nm (Typ.) AlGaInP laser diode with low threshold current. The low threshold current and short wavelength are achieved by the use of a strained multiple quantum well active layer. The lasing wavelength is 635 nm (Typ.) which is 8 times brighter than that of 670 nm lasers. DL-3148-023 is suitable for battery powered laser pointers due to its low operating current and voltage.
