The Fresnel lighting character works best with a large aperture and a wide zoom range. Despite its large aperture, the Orbiter Fresnel lens housing is compact (approx. 340 mm x 380 mm x 370 mm / 13.4 in x 15 in x 14.6 in) and lightweight (~ 4.5 kg / 9.5 lbs). Its lens diameter of 285 mm / 11.2 in equals that of the True Blue ST2/3 and T5. The large zoom range of 15 to 65° is fully motorized and can be precisely positioned while being controlled locally via Orbiter’s Control Panel or remotely by DMX/RDM or IP based (ArtNet or sACN). The Orbiter Fresnel lens will be available in black.

While the idea for Hoya360 emerged about five years ago, it only began to take shape two years ago, with the design process beginning last year. The portal itself is based on Salesforce, a widely-used customer relationship management software.

“When you talk to alumni about what defined their time at Georgetown on the hilltop, they use the word home. We really wanted Hoya360 and the overall GU360 project to strengthen that sense of home while they were here for the four years on the hilltop, and then extend it to when they leave the hilltop,” Little said.

The yokes for Orbiter come with a newly developed release system that allows for quick change from a manual version lamphead to a pole operated version. The 28 mm spigot (Junior pin) is already mounted on the yoke. No tools needed for setting up Orbiter.

This intuitive design makes changing colors or finding a setting easier than ever before. In addition, the control panel is removable and can be used handheld with the aid of a control panel cable.

Vice President for Information Technology and Chief Information Officer Judd Nicholson said the idea for a new system arose from two areas: a desire to revamp the alumni relationship network and student-voiced concerns about locating information.

Lenses of longer focal lengths are generally capable of producing narrower depth of field (partly because, as we learned above, an F1.4 aperture in an 85 mm ...

The ARRI Orbiter is a versatile, tuneable, and directional LED fixture including a six-color light engine. With its changeable optics, Orbiter can transform into many different types of lamphead.

Orbiter’s unique Quick Lighting Mount (QLM) system allows the Orbiter Fresnel lens to be mounted safely and quickly. ARRI accessories like the 4 and 8-leaf barndoors can be added to the new Orbiter Fresnel lens to enable a perfect cut. Physical gels can also be used in addition to the more than 300 already pre-programmed gels available for Orbiter.

“When you become an alumni, we want to talk to you and have conversations with you that’s representative of your experience at Georgetown, and we did get a lot of complaints from students about not being able to find things, not knowing who to go to,” Nicholson said. “Those two ideas, those two issues, really converged together.”

The Office of the Chief Information Officer presented its forthcoming centralized information portal, Georgetown360, which will be rolled out at the end of the month for the School of Nursing and Health Studies.

Nicholson said the larger hopes for this initiative include introducing Hoya360 in the School of Continuing Studies, the Georgetown University Law Center, the Georgetown University Medical Center and the other graduate programs, as well as creating a portal for parents to access important information.

The new portal, Hoya360, will integrate all current sources of club and academic information for Georgetown students in one location. A version of the portal has already been implemented for faculty, while a version for alumni will be formally launched with the student portal by the end of the month, according to the platform website.

Nicholson said the rollout will begin with NHS students because its population is a model of the greater school community.

Many student groups contributed to the project, including the Georgetown University Student Association’s Student Technology Advisory Board and the NHS Academic Council.

The Orbiter Fresnel Lens creates a precise light spot with a soft single shadow, and it delivers true Fresnel output with a real Gaussian field of light. The light output of Orbiter with the Fresnel lens is comparable to the ARRI L-Series L10 and True Blue ST2/3 with 2000 W Tungsten bulb.

The Open Face Optics produce a high-output, directional beam of light in several different beam angles including 15°, 30°, and 60°. They are perfect for throwing light long distances or providing a broad swath of light. The accessory slot can be used with modifiers such as barndoors or snoots.

ARRI accessories like the 4- (L2.40950.0) and 8-leaf (L2.40960.0) barndoors can be added to the new Orbiter Fresnel Lens to enable a perfect cut. Physical gels can also be used in addition to the more than 300 already pre-programmed gels available for Orbiter.

The entire concept of Hoya360 represents a way that Georgetown is adapting and keeping up with the changing technological world and being responsive to student needs, according to Little.

Combined with Orbiter’s ARRI Spectra light engine, the high-end optical system is perfectly suited for cinematic application, broadcast studios, as well as theaters or live productions. The Orbiter Fresnel lens is a great addition to the already existing Orbiter Open Face Optics 15°, 30°, and 60°.

Currently, Georgetown utilizes a variety of different systems and websites for students to access information, including MyAccess, Blackboard, Canvas, and the Georgetown University website. With the implementation of Hoya360, some of those services may be gradually retired.

One of the largest challenges throughout this project was the integration of older Georgetown technologies, such as MyAccess into the new portal.

“There were a number of technical challenges, and it’s been a long process, so I think the other challenge I would say is keeping people engaged and excited and informed, and making sure we consider stakeholders’ input,” Nicholson said.

On the occasion of our 100th anniversary of ARRI Lighting in 2024, we are giving you 3 Open Face Optics (15°, 30°, 60°) on top of every Orbiter Beam Set.

Redesigned from the ground up, the Orbiter control panel is an evolutionary step in light fixture control. Including a 4" full-color display, quick navigation buttons, and integrated sensors, the Orbiter control panel allows for easy use with a graphic user interface. Simplified menu structure and reimagined user interfaces provide one-glance operational views and uncluttered screens.

In addition to function, the development of Hoya360 also focused on the site’s aesthetic, keeping in mind the desires and expectations of its target audience. Student input was brought in from the beginning and it has helped focus the platform on the user experience and make it unique.
