Datasheet: DUV Integrating Sphere Series MgF-AL Coated Spheres For VIS And NIR Applications

SphereOptics is pleased to introduce a series of integrating sphere assemblies featuring our new magnesium fluoride over aluminum (MgF-Al) coating process. The DUV series integrating spheres including 2-inch, 4-inch and, 6-inch diameter spheres with a choice of three (3) or four (4) ports. Each sphere assembly includes a baffle, SMA Adapter, TO5 Detector Adapter and port plugs coated with our new MgF-Al deep UV coating.

About our MgF-Al Sphere Coating
Aluminum has a high intrinsic reflectance value in the UV region above 100 nm. The protective overcoat of magnesium fluoride helps protect the aluminum and optimizes its reflectivity. Our new MgF-Al coating is quickly becoming an industry and national laboratory choice of coating for applications in the UV wavelength regions. The coating is efficient for applications covering the 100 to 400 nm range and is more stable than PTFE materials in that region. Our deep UV coating provides three major advantages for use in the 100 to 400 nm region: non-fluorescence, damage resistance, and high stability. The coating has a reflectance of >90% over the wavelength region from 1000 to 2500 nm, so may also be used effectively for many VIS and NIR applications.
