Broadband Optical Modulator (BOM)

The BOM Component is designed for economical optical modulation at speeds of up to 200kHz.

Broadband Optical Modulator is an optical modulation component for speeds up to 200 kHz. It offers a low-cost alternative to acousto-optic modulators and electro-optic modulators in this range. The modulator component works as a reflective diffraction grating, chopping the beam by varying between an unpowered flat mirror-state and a powered diffractive state in a binary fashion. With an optical module that easily fits into a standard 1” optical mount, the BOM System is operable with connection to a standard high voltage power supply.  This product will be available soon through the Thorlabs website.
