G&H (LON:GHH), a global leader in advanced photonics and optical solutions, will exhibit at SPIE Defense + Commercial Sensing (DCS) from April 15–17, 2025, at the Gaylord Palms Resort & Convention Center in Orlando, Florida. Visit Booth #811 to explore G&H’s latest shortwave infrared (SWIR) continuous zoom lens innovations for aerospace and defense.
“We’re excited to return to DCS to spotlight our advanced SWIR capabilities,” said Jacob Oh, Business Development Director of Optical Systems at G&H. “This year’s showcase highlights our purpose-built FireAnt lens series and ruggedized G&H | Stingray systems, engineered to deliver mission-critical performance in the harshest environments.”
At the event, G&H will showcase its FireAnt SWIR continuous zoom lens assembly—designed with a constant F/5.6 aperture through zoom, achromatic correction, and ruggedized housing for land, air, and maritime applications. Optimized for 0.9–1.7 µm and supporting up to 16.4 mm HD image formats, the FireAnt 40–400 mm system delivers superior resolution, transmission, and focus stability without the vignetting typical of visible-recoat SWIR approximations.
Visitors can experience G&H’s full portfolio of SWIR lens solutions, including:
FireAnt Series – Ruggedized continuous zoom lenses (40–400 mm and 80–800 mm) with constant F/5.6 aperture, no vignetting, and achromatic correction. Each lens is ruggedized for defense applications and ships with the StingWare™ controller for active athermalization and precise feedback.
Fuschia Series – Fixed SWIR lenses supporting 0.9–1.7 µm, available in a wide range of focal lengths and mechanical styles to suit both lab and field environments.
GhostSight Series – Achromatically corrected VisSWIR lenses (0.45–1.7 µm), ideal for multispectral imaging and inspection applications.
Beyond the hardware, G&H’s strength lies in its full-lifecycle capabilities—from optical and optomechanical design to environmental modeling and cleanroom assembly. In-house finite element analysis (FEA), interferometric testing, and thermal chamber qualification ensure that every lens is engineered for performance and built to endure.
G&H will also participate in two technical sessions at DCS 2025, sharing insights into ruggedized optics and domestic crystal growth for advanced photonics.
Thermosense Vendor Session
April 14, 2025|1:00 PM – 5:00 PM EDT|Tampa 2, Ballroom Level
Presentation: Continuous Zoom Lenses for SWIR & MWIR (Thermal Imaging) Applications
Jacob Oh, Business Development Director, G&H
Get a first look at G&H’s latest ruggedized SWIR and MWIR lens assemblies, including continuous zoom innovations that deliver performance across land, air, and maritime platforms. This early session helps attendees prioritize key technologies before the show floor opens.
Thin Film Lithium Niobate Workshop
April 15, 2025|1:00 PM – 5:00 PM EDT|Tallahassee 1/2, Ballroom Level
Presentation: United States domestic lithium niobate supply chain and opportunities
Dr. Matt Whittaker, Manager – Crystal Growth and Inertial Confined Fusion, G&H
Matt will present a detailed overview of current LiNbO₃ crystal supply chain capabilities in the U.S., including boule size, dopant options, wafer specs, and opportunities for scaling to meet Thin Film Lithium Niobate (TFLN) demand.
Panel Discussion: Materials Scaling and Manufacturing Requirements and Challenges
Dr. Matt Whittaker, Manager – Crystal Growth and Inertial Confined Fusion, G&H
Matt will also join fellow industry experts from Phase Sensitive Innovations, AFRL, and Apex Microdevices for a moderated discussion on the road ahead for U.S.-based lithium niobate manufacturing.
Don’t miss these sessions if you're tracking the future of IR imaging or the U.S. lithium niobate supply chain.
Find Us at Booth #811 the Gaylord Palms Resort & Convention Center in Orlando, Florida.
G&H’s Application Engineer, Zachary French, and Regional Sales / Business Development Manager, Amber Contant, will be on the booth to provide insights into the development of SWIR CZ systems, including the mechanical and optical considerations that underpin the FireAnt and G&H | Stingray series.
With a strong heritage of supporting U.S. DoD primes and integrators across gimbals, fire control, targeting, and surveillance platforms, G&H continues to push beyond the boundaries of what’s possible in photonics. Our vertically integrated global network—from Keene, NH to Ilminster, UK—ensures end-to-end control of materials, coatings, and quality.
Join G&H at Booth #811 to see how we’re advancing shortwave imaging—and photonics technology more broadly—through rugged innovation and precision design.
