Chief Lens Support for ScreenStar Conversion Lenses

The Chief Lens Support NAV1 is engineered to simplify how Navitar ScreenStar Conversion Lenses—specifically the SSW08 and SST120—integrate with any RPA projector mount. This precision accessory is designed to maximize versatility, improve alignment, and protect image quality across a range of projector sizes and configurations. If you’re upgrading your projection setup or standardizing across multiple rooms, this lens support delivers the dependable performance you expect from Chief, while keeping installation fast and adjustments effortless.

• The NAV1 enables quick, reliable adaptation of Navitar ScreenStar Conversion Lenses to any RPA projector mount, bridging compatibility gaps and streamlining installs. By providing a stable, purpose-built interface, it eliminates ad hoc mounting solutions that can lead to misalignment or inconsistent image geometry. This is particularly valuable in environments where multiple projectors or lenses are used, or where replacement parts must be sourced rapidly, ensuring you can maintain a consistent projection workflow without sacrificing image integrity.
• Designed with flexibility in mind, the NAV1 supports maximum adjustment to accommodate different projector sizes and lens placements. Its adjustable lens plate and mounting geometry allow technicians to dial in tilt, yaw, and vertical position with precision, so the ScreenStar Lens remains centered in the mirror, the projection path stays clean, and keystone distortion is minimized. This adaptability is essential for maintaining sharp focus and uniform brightness across a range of throw distances and mounting heights.
• It addresses a common challenge with short focal-length lenses: images produced by lenses shorter than 2 inches can exceed the mirror’s capacity if not properly managed. The NAV1’s design accounts for this by providing optimized lens positioning and mirror clearance, helping to prevent image clipping and ensuring the full frame projects onto the intended mirror surface. In practice, this means more consistent edge-to-edge brightness and fewer adjustments after installation.
• Quality construction and durable performance are built into every aspect of the NAV1. The unit is engineered to withstand the rigors of frequent use in education, corporate, and staging environments. The materials, fasteners, and finish are chosen for long-term stability, resisting vibration and thermal shifts that can creep into optical setups. This reliability translates into fewer recalibrations, lower maintenance, and greater confidence in your projection system over time.
• With a focus on ease of use, the NAV1 simplifies the process of swapping lenses or repositioning a projection path. Its intuitive mounting interface reduces downtime during upgrades and service calls, while secure locking mechanisms keep the lens position fixed once calibrated. Whether you’re setting up a single room or outfitting a network of classrooms or conference spaces, the Chief Lens Support helps you deliver a consistent, high-quality image with minimal friction.

how to install Chief Lens Support

• Verify compatibility: Confirm that you are using Navitar ScreenStar Conversion Lenses (SSW08 or SST120) in combination with an RPA projector mount. This ensures correct interface geometry and reliable performance once installed.
• Prepare the projection path: Before mounting, inspect the mirror surface and projection path to ensure there is unobstructed clearance for the lens and any adjustment mechanisms. Clean surfaces as needed to prevent debris from affecting alignment.
• Attach the NAV1 to the RPA mount: Secure the Chief Lens Support to the projector mounting framework using the approved fasteners. Tighten to the manufacturer’s recommended torque to prevent drift while still allowing for deliberate adjustments during alignment.
• Install the ScreenStar Lens: Mount the Navitar lens onto the NAV1 interface, aligning screw posts and plate holes as specified in the installer’s guide. Ensure the lens sits squarely and the lens plate engages securely with the rail or dovetail system provided by the NAV1.
• Fine-tune alignment and lock in place: Use the NAV1’s adjustment features to dial in tilt, yaw, and vertical positioning so the lens projects cleanly onto the mirror with minimal edge distortion. Once the alignment is verified, engage locking mechanisms to preserve the calibration during operation.

Frequently asked questions

• Q: What lenses are supported by the Chief Lens Support NAV1?
  A: It is designed to adapt Navitar ScreenStar Conversion Lenses, specifically the SSW08 and SST120, to RPA projector mounts. If you rely on these lens models for screen or mirror-based projection paths, the NAV1 provides a plug-and-play interface.
• Q: Why is the 2-inch lens size note important?
  A: Lenses shorter than 2 inches can produce images that are larger than the mirror’s capacity if not properly positioned. The NAV1 addresses this by enabling precise placement and clearance so the image remains within the mirror bounds, preserving image integrity and avoiding clipping.
• Q: Do I need professional tools to install the NAV1?
  A: Installation is designed to be straightforward with standard mounting hardware found on RPA projectors. While no specialized tools are required, following the manufacturer’s installation guide for torque settings and alignment procedures will yield the best results and protect long-term calibration.
• Q: How does the NAV1 improve long-term reliability?
  A: By offering a robust, purpose-built interface with maximum adjustment range and secure locking, the NAV1 maintains alignment even with lens swaps, vibration, and routine servicing. This reduces drift, minimizes recalibration downtime, and extends the lifespan of your projection setup.
• Q: Can the NAV1 be used with multiple projectors in a network?
  A: Yes. The NAV1’s adjustable design is suitable for environments where different projectors or lenses are used across rooms. It provides a stable baseline so repeated lens changes or reconfigurations do not compromise image quality.
