Panasonic ET-D75LE90 Ultra Short-Throw Lens

Ultra Short-Throw Projection
Extremely short projection distance – Can project a 100-inch image from just ~0.25 meters (25 cm) from the screen.

Ideal for small rooms or installations where space is limited.

High Optical Performance
4K-resolution support – Compatible with 4K DLP projectors, delivering sharp, detailed images.

High brightness retention – Maintains high lumen output (optimized for Panasonic’s 50,000-lumen laser projectors).

Low distortion – Advanced optics minimize image warping.

Motorized Focus & Zoom
Motorized adjustments – Allows for remote-controlled focus, zoom, and lens shift.

Precision alignment – Simplifies setup and calibration.

Lens Shift Capability
Vertical & horizontal lens shift – Enables flexible installation without keystone distortion.

Vertical shift: ±60%

Horizontal shift: ±10%

Robust Build for Professional Use
Durable construction – Designed for 24/7 operation in commercial/rental environments.

Sealed optics – Dust-resistant design for long-term reliability.

Compatibility
Designed for Panasonic PT-RZ and PT-RQ series laser projectors (e.g., PT-RQ50K, PT-RZ21K

The Ultra Short-Throw Lens for Panasonic 3-Chip DLP Projectors enables large screen projection from a short distance. The 200" diagonal image can be produced from a distance of about 5.0" (1.5 m) away from the screen. Other short throw projection is possible by exchanging the lenses.
