Optoma BX-DL100 Short Throw Projector Lens

The Optoma BX-DL100 is a short throw zoom lens designed for professional AV installations where projection distance is limited. Compatible with the Optoma W505, EH505, EH503, and X605 projectors, this lens significantly reduces the throw distance required to fill a screen, making it an essential accessory for smaller conference rooms, classrooms, retail displays, and rear-projection applications where the projector must be positioned close to the screen surface.

The lens attaches via a manual bayonet mount, allowing installers to swap lenses quickly without tools — a practical advantage during setup or when the same projector is used in different venues with varying throw requirements. Zoom and focus are adjusted manually using the lens barrel rings, giving the installer hands-on control over image sizing and sharpness. While the lack of motorized control means adjustments cannot be made remotely, the manual design keeps the lens straightforward and reliable for fixed installations where settings are dialed in once and left in place.
