ZnSe vs. ZnS Windows: Choosing the Right IR Material for 2026 Defense and Medical Systems
In 2026, advancements in thermal imaging, medical diagnostics, and defense technologies demand precise and durable optical materials. For applications like drone-based thermal sensors or surgical lase...
Aspherical Lenses
Hyperion's aspherics capabilities can deliver high-precision aspherical surfaces from VIS imaging system to athermal lenses for LWIR applications. Material options include ZnS, ZnSe, Ge, CaF2, Chalcogenide, and more.
Infrared Lenses
Hyperion regularly work with IR materials that spans across almost the entire IR spectrum. We use laser-based edging device to control MWIR and LWIR lenses' decenter deviation, and test on reflective centering station to fulfill extremely precise tasks.
Optical Design & Assembly
Hyperion's expert engineering and production teams work on 80+ custom lens projects every year. Our services range from feasibility research, design specifications verification, preliminary design, design optimization, cost/ performance analysis, to prototyping and volume production.
Prisms
Hyperion supplies a wide range of prisms to meet UV-Visible-NIR applications. Our capabilities can fulfill high-precision surface quality and tight angle tolerance. Materials selection ranges from flint/crown glasses, fused silica, ZnSe, CaF2.
Windows
Our precision optical windows range from UV to VIS, NIR, SWIR further MWIR and LWIR applications. We offer a variety of substrates, such as Germanium (Ge), Silicon (Si), N-BK7, UV Fused Silica, Zinc Selenide (ZnSe), or Multiple anti-reflection coating options are available for the Ultraviolet (UV), Visible, or Infrared (IR). Please also refer to our IR optics category for more information.
Dome
Glass domes are widely used for commercial applications which require protective boundary between different environments; domes perform as windows, providing protection to electronic sensors or detectors without sacrificing field of view.
Laser Optics
Protect scan lenses from backsplatter and other workplace hazards, Hyperion Optics offers protective windows -- also known as debris windows -- that are either included as the overall scan lens assembly part, or sold separately. These plano-plano windows are available in both ZnSe and Ge materials and also supplied mounted or unmounted.
LWIR Lenses
LWIR lens plays a critical role in thermal imaging surveillance applications, beyond night vision capabiliity, critical targets differentiation in poor vision conditions is considered the most practic...
