NDL3321ST
DESCRIPTION t The NDL3321ST and NDL3321SU are Al Ga In P 650 nm visible laser diodes and especially developed for DVD,
DVD-ROM. The newly developed Multiple Quantum Well (MQW) LD chip, can achieve low operating current, wide c temperature range.
Use of a CD package allows easy replacement of conventional 780 nm LDs. u FEATURES d
