Barco EN61 FLDX lens (1.7 - 2.5 : 1) - R9802241

Product Overview

The Barco R9802241 EN61 FLDX lens is a motorized zoom lens for Barco F-series single-chip DLP projectors, including the F35, FL40, F70, F80 and F90 platforms. With a 1.7-2.5:1 throw ratio (WQXGA) and 1.58-2.33:1 at WUXGA, it covers standard mid-room placement for many fixed installs and rental setups. The lens is optimized for WQXGA resolution and includes an encoder for repeatable positioning. Motorized zoom and focus with memory make it well suited to multi-source venues where lens positions must be recalled reliably.

Product Description

The R9802241 is part of Barco's FLDX lens range for the F-series projector family. It offers a 33.7-49.54mm focal length, an f/2.1-2.5 aperture and a 1.47x motorized zoom, with a focus range from roughly 4.9 to 49.2 feet. The EN61 designation indicates encoder-equipped optics optimized for WQXGA, giving precise, repeatable zoom and focus recall. On the F80 the throw ratio shifts to approximately 2.38-3.51:1 (4K/WQXGA), and a lens adapter is required for that body. The product image shows the lens barrel and mount used across the F-series.

Key Features

• 1.7-2.5:1 throw ratio (WQXGA) — 1.58-2.33:1 at WUXGA, covering common mid-room projector placement.
• Motorized zoom and focus with memory — 1.47x zoom with encoder-based recall for repeatable lens positions across sources and events.
• f/2.1-2.5 aperture — high-quality optics for bright, sharp images from F-series light engines.
• 33.7-49.54mm focal length — published optical data simplifies screen-distance calculation.
• WQXGA optimization — the EN61 design is tuned for WQXGA resolution with an encoder for precise control.
• Broad F-series compatibility — works with F35, FL40, F70, F80 and F90 projectors (F80 requires a lens adapter).
• Compact, lightweight design — about 2.6 kg, easy to install and transport for rental use.

Typical Applications

• Fixed installations using Barco F70 or F90 single-chip DLP projectors.
• Auditoriums and lecture theaters with standard mid-room projector placement.
• Houses of worship running F-series projection over a moderate throw distance.
• Rental and staging where motorized lens memory speeds source and venue changes.

Technical Specifications

Frequently Asked Questions
