This RF Emitter/Transmitter by 3D VIP is the same as the Optoma BG-BC100 RF Emitter as they are made by the same manufacturer.  The only difference is of course the lower price.  We have tested these personally and it works perfect on any of the Optoma projectors that have the 3D Vesa Sync Port on the back.  Models include the HD25 HD25-LV HD131X HD300X HD33 HD3300 GT750 GT750E HD83 HD8300, etc. This listing also includes the Vesa 3D Sync Cable which you will use to hook up the emitter to your Optoma Projector, Optoma 3D-XL Adapter, 3D Now & 3D VIP Theater processor, JVC D-ILA Projector with 3D Sync Port, etc.  

This RF Emitter is compatible with RF 3D Glasses by 3D Now, 3D VIP, Optoma, and Monstervision.
