GBvi Launches Atlas-4 Projector Mount Solution

gbvi atlas-4 projector mountSussex, UK – 22 November 2018 — GBvi, an industry leader in the development of high performance projector optical blending solutions and display technology products, has announced the release of its Atlas-4 projector mount. Visitors to the I/ITSEC 2018 show in Orlando, Florida, from 26-30 November can see Atlas-4 on the Immersive Display Solutions Inc. stand (#1273) – GBvi’s partner stand.

The Atlas-4 projector mount has been designed to significantly ease projector installation and optical alignment, with four degrees-of-freedom adjustability. Atlas-4 robustly interfaces a projector to the support structure while providing all necessary mechanical adjustments to optimise projection geometry.

Geoff Blackham, GBvi’s founder and managing director, explains; “With GBvi’s depth of experience and expertise, we are frequently asked for support and advice that goes beyond optical blending. One aspect in particular has been that accurate projector installation and alignment is important to achieve the required performance, yet often time-consuming.

“By designing a family of projector mounts that not only eases interfacing to Chronos optical blending but also behaves the way installers like for predictable alignment, a complementary addition to our product range has emerged.”

Well-suited to a wide range of display applications including simulation, planetariums, live events, staging and entertainment, the Atlas-4 semi-custom configuration accommodates a wide range of projector models including the Barco F70 and FL40, Sony VPL-GTZ270/280, and Norxe P1. Its high configurability means that Atlas-4 variants for other projectors are easy to introduce.”

Blackham continues; “After listening to customer and market feedback, we’ve developed a unique solution that’s motion compatible and can sit under the projector body without compromising tight projector cluster designs typical in simulator designs.”

Meet GBvi at I/ITSEC 2018 on stand #2615

In addition to Atlas-4, GBvi will be showcasing Chronos Glass: Greyscale and Chronos Rewind at this year’s I/ITSEC – the world’s largest modelling, simulation, and training conference – with a dedicated on-stand demonstration featuring two Norxe P1 projectors.

Chronos Glass: Greyscale from GBvi addresses the ‘small 4K’ and 8K class of projection systems where some optical trade-offs are most challenging, particularly with laser-phosphor illumination.

Chronos Rewind is GBvi’s dedicated solution that allows for Auto Alignment systems to be integrated alongside Chronos optical blend masks as part of multi-channel projected displays.

GBvi solutions can also be discovered by visitors to the Immersive Display Solutions, Inc. (IDSI) stand (#1273) where Chronos Glass: Greyscale, Chronos Rewind and Atlas-4 will be in use with Barco FS40 projectors and IDSI’s new low-cost curved screen.

GBvi to Exhibit at I/ITSEC 2018

GBvi will again be exhibiting at I/ITSEC in Orlando. 

Visit us on Stand #2615 from 26-30 November.

More details on our on-stand demonstrations and product releases will be made available in the lead-up to the show.


The Interservice/ Industry Training, Simulation and Education Conference (I/ITSEC) is the world’s largest modelling, simulation, and training conference.

Held near the beginning of December in Orlando, Florida, USA, I/ITSEC consists of peer-reviewed paper presentations, tutorials, special events, professional workshops, a commercial exhibit hall, a serious games competition, and STEM events for teachers and secondary students. I/ITSEC is organised by the National Training and Simulation Association (NTSA), which promotes international and interdisciplinary cooperation within the fields of modelling and simulation (M&S), training, education, analysis, and related disciplines at this annual meeting. The NTSA is an affiliate subsidiary of the National Defence Industrial Association (NDIA). Hence, I/ITSEC also emphasizes themes related to defence and security.

GBvi to Premier Two New Technologies at I/ITSEC 2017

Sussex, England — 16 November 2017 — GBvi, an industry leader in the development of high performance projector optical blending solutions for out-the-window simulation and training, will be launching two new optical blend technologies at I/ITSEC 2017 in Orlando, Florida, from November 27th to December 1st. On the GBvi stand (#2736), conference attendees can see a live demonstration of two innovative new products – Chronos Greyscale and Chronos Rewind.

GBvi’s Chronos range of optical blending solutions enable display system integrators to achieve an even black level across multi-channel projection displays, realising the maximum dynamic range and enhancing the perception of life-like imagery.

Two new product additions to the Chronos range will be premiered for the first time by GBvi at IITSEC with on-stand demonstrations at the show.


Chronos Greyscale

Chronos Greyscale is the new specialist GBvi optical blend technology that addresses the ‘small 4K’ and 8K class of projection systems where some optical trade-offs are most challenging, particularly with laser-phosphor illumination.

Chronos Greyscale is qualified for use with LED and laser phosphor projectors .

Chronos Rewind

“Use of Auto-Alignment (AA) systems for projection display calibration is becoming universal.” Geoff Blackham, founder and managing director of GBvi, explains. “While these systems produce excellent results, some perform best after removal of the blend masks from the light path to enable alignment and calibration to take place.”

Designed for use with a broad range of digital displays, Chronos Rewind addresses this issue, using an actuated platform and simple trigger interface to move the blend mask to and from the projector lens as required in a carefully controlled and precise manner.

This process allows for the blend to be retracted from the lens, auto calibration to be completed, and for the blend mask to be returned to its original, correct position.

Chronos Rewind allows for AA systems to be integrated alongside our Chronos optical blend masks as part of multi-channel displays.

“Our expertise in the field of projection display systems means we can provide an unrivalled service, helping customers with the whole display challenge – not confining our input to the blending alone.” says Blackham.

GBvi’s optical blending technology enables integrators to provide display systems which are free from the visual issues caused by digital blending. This means no ‘double-bright’ overlap regions, and no impact to contrast or dynamic range, as black level infill is no longer necessary to match blend brightnesses.

Chronos has been successfully implemented on WUXGA, WQXGA and 4K single-chip DLP, WUXGA and 4K 3-chip DLP and 4K LCoS projectors, including lamp, laser-phosphor and LED illuminated models.

I/ITSEC 2015 – and the move away from lamp to solid-state projection

In December I was lucky enough to get to I/ITSEC and meet once more with many friends in this industry. 

I/ITSEC (see iitsec.org), a perennial event that’s always right after Thanksgiving in Orlando, is a conference and exhibition specifically focused on Training & Simulation.

For us at GBvi the main interest is projection displays – projector companies, systems integrators and related technologies.

DLP projectors continue to dominate in dome and high-light-output applications and indeed continue to improve, for example with motion blur performance, wobbulation to increase addressability (a subject for another blog, perhaps…) and ultra-short throw lens options.

A notable trend that many have commented on is the move away from lamp illumination towards solid-state – LED and laser phosphor illumination to be specific.  LED illumination has been around a while now and has successfully occupied niche applications in simulation visual systems where the very stable output and low maintenance overhead is of most importance, while the relatively limited light output is enough – particularly in cross-cockpit collimated visual systems.

Laser phosphor projectors extend the benefits to higher-output applications such as domes, as several thousand lumens are now available per unit.  So lamps beware – the writing is on the wall!

A notable non-trend, however, is that DLP projectors are stuck with relatively low native sequential contrast (full white to full black).  Considering that laser phosphor illumination is likely to substantially reduce lifetime related issues with LCOS projectors – its main weakness – and that LCoS still has the edge with native pixel counts (‘resolution’) and sequential contrast, it seems that competition between these projection technologies is set to continue, at least within the T&S market.

Watch this space…..
