He-Ne Laser
Ando AQ4302
The Ando AQ-4302 He-Ne laser light source is primarily designed for identifying a particular core during installation of single-mode or multimode multi-core fiber cables. This light source also permits detection of fiber breaks near cable connections or visual inspection on fiber end-cuts. The Ando AQ4302 can also be used for wide-band Optical Spectrum Analyzer calibration at 632.8 nm.

Features
________________________________________________

A gas laser is employed to obtain emission of a constant wavelength

Applicable for both single-mode and multimode fiber cables

For safety reasons, no laser beam is output unless a fiber cable is plugged into the output connector

Compact, lightweight, and easy to handle because the power unit and laser tube are one unit.
