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...
Beyond Visible Light: What Does a Germanium Lens Do?
To the untrained eye, a germanium lens might appear to be a solid, opaque, mirror-like piece of metal. Yet, for advanced infrared (IR) optics, it is as transparent as high-quality glass, enabling grou...
Optical 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 detect...
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.
IR Aspherical Lenses
At Hyperion Optics, we work with various infrared materials. Besides spherical parts, with increasing demand of IR aspheric components, designers are more likely to use aspheric parts in LIRP projects...
ZnSe ZnS window
· Low Dispersion· Available Uncoated or AR Coated· Ideal for Thermal Imaging, FLIR, and Medical Systems Hyperion Optics® Zinc Selenide (ZnSe) Windows are ideal for a wide variety of infrared applicatio...
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.
Gallium Arsenide Lenses
GaAs is semi insulator, which can be used in large power continuous CO2 laser system to replace the zinc sulfide in lens or mirror forms. GaAs is suitable in applications consists of toughness and dur...
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.
Zinc Selenide Lenses
Zinc Selenide has great transmittance through the band 0.5-22μm, especially at 10.6μm, and is commonly used in thermal imaging and FLIR systems, also its outstanding low absorption coefficient and h...
Zinc Sulfide Lenses
With the rapid development of military weaponry and correlative targeting and monitoring systems, ZnS is widely utilized in multi-spectral IR applications. Its relatively high transmittance through 3-...
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.
