The BRM-6301 represents a significant advancement in divergence angle analysis — a fully automated instrument engineered specifically for characterizing laser diodes with large divergence angles. It effectively overcomes the limitations of traditional beam profilers, which are designed only for lasers with small far-field angles, delivering comprehensive angular distribution profiles in both polar and Cartesian coordinate systems, with optional half-intensity angle (FWHM) reporting.

The system offers flexible configuration, allowing the detector to be selected based on the wavelength of the tested LD, and the mounting base to be customized according to the package type. It can also be used for angular distribution measurement of LEDs. Optional accessories such as the BRM-610X series laser drivers, BRM-620X series temperature controllers, and laser mounting bases enable expanded functionality for measuring device characteristics including P-I-V curves, threshold current, and WPE.
