1.3 mm High-Power Laser-Diode DIP Module
GENERAL DESCRIPTION
The OL3201N-40 and OL3204N-40 are extremely high power, 1.3 mm laser-diode DIP modules
with single-mode fiber pigtails. The OKI laser chips achieve single-mode fiber output of over
40 mW. These modules are optimal light sources for optical measuring instruments and other
systems that require high power.
