ZnSe Infrared Beam Splitters for MWIR and LWIR Systems

Custom zinc selenide beam-splitting optics

ZnSe is widely used for infrared transmission and beam-splitting applications where MWIR or LWIR optical performance is required. Junbang produces ZnSe beam splitters according to customer drawings, including geometry, thickness, clear aperture and coating requirements.

Beam splitter performance depends on substrate material, coating design, incident angle, polarization, wavelength band and environmental conditions. We review these requirements before production to support stable optical performance.

Projects can include plate beam splitters, wedge beam splitters and special infrared optical components for optical testing, imaging, sensing and laser systems.

Typical applications

• Infrared optical testing and alignment systems
• Thermal imaging and LWIR camera modules
• CO2 laser and infrared laser optical paths
• MWIR/LWIR sensing and spectroscopy assemblies

RFQ information we recommend sending

Please include drawings, material, dimensions, quantity, wavelength range, coating requirements, angle of incidence, surface figure, surface quality, roughness, environmental requirements and inspection report needs. This helps us review manufacturability and quote faster.
