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.

LOVE this tough toy! My teething puppy is still enjoying it!
Color: Hedgehog
LOVE the hedgehog! Very tough! My dachshund has not been able to chew off any of the 'nubs', and does she try! lol The only thing is, the first thing she did was chew off the nose, but I discarded it and watched her closely to make sure she didn't chew off any more, and no, its still being chewed on. Wish I could find more toys like this one!!

still searching for a truly indestructible dog chew toy
Color: Hedgehog
My smallish dog (15 lb Boston terrier) got this chewed up within a half an hour. I didn't notice right away that he was also eating the parts he chewed off. Didn't last a day. Otherwise, quick shipping for a cute toy.

Good size for my pug!
Color: Dentachew 3 Pk
I love how it’s a good size for my pug it is easy for her to play around with. I had stuffed animals for her to play around with but it looked so silly to watch her play with something that is 10 times as big as her 😂. I had to buy her these toys and she seemed so happy when she first got them. It was so funny and interesting that she had to chew all three toys and decide which one she liked. At first she decided to play with the rope toy and she liked the rope toy, then she got curious with the rubber toys. She has decided that the rubber toys are her favorite and I’ve tried to engage with playing with her with the rope toy. She gets more interactive with the rubber toys! She also looked so relieved while chewing them so that’s a plus!

Good for Teething puppies
Color: Teething Stick
After getting my fingers chewed and bitten by my new foster - 8 week old Yorkie , I was desperate to find good teething toys. Fortunately this one arrived quickly. Turned out to be very good for teething puppies! Charlie loves this cooling stick. Once it’s frozen, the cold really seems to soothe his sore gums. The icy part doesn’t stay frozen for long, but it works so well that I bought a second one to keep ready in the freezer while he’s working on the first. Even after it warmed up, he still enjoyed chewing on the soft stuffed part and the tentacles. The product card says not to use it as a chew toy, so supervision is a must, but it held up just fine so far. Overall, this has been a big help during the teething phase — short-lived when frozen, but very effective while it lasts! And worth every penny to save my fingers from being a chew toy.

From Puppy Teething to Adult Favorite – 7 Years Later
Color: Teething Stick, Color: Teething Stick
This has been one of the best toys I’ve ever bought! My dog has loved the Pupstages Cool Teething Stick since she was a tiny puppy, and now at 7 years old, it’s still one of her absolute favorites. It’s been amazing for soothing teething when she was little, and now she still enjoys chewing on it and carrying it around. It’s held up surprisingly well over the years, especially considering how much use it’s gotten. I also love that you can cool it for extra relief—it really helped during those puppy stages. If you’re looking for a toy that lasts and actually becomes a long-term favorite, this is definitely it. Highly recommend for both puppies and even older dogs who still love a good chew! 🐶
