Introduction:
Ball lenses are highly polished spheres made of optically transparent homogeneous materials. Carefully controlled manufacturing process produces spheres with precise diameters and unsurpassed surface quality. Ball lenses are great tools for improving signal coupling between fibers, emitters and detectors.UVFS glass comes with low refractive index, much better thermal stability and wider transmission band from UV to NIR.

Substrate Material:
UVFS glass - deep UV grade
Wavelength Range:
200 - 2500nm
Lens Design:
Half-ball/Hemispherical surface, and specially truncated from bottom/plano surface
Radius of Curvature(ROC):
ROC=12.7, -0.1/0mm(Radius of Curvature of half-ball lens)
Center Thickness(CT):
CT=11.7, +/-0.1mm (i.e. 1.0 +/-0.1mm  down truncated from flat bast surface of hemi-spherical lens)
Edge Surface: None; Edge thickness (ET) = 0, specially processed.
Surface Quality:
Spherical surface:
40/20 scratch and dig; Surface accuracy: <lambda/4 @ 633nm; Clear aperture: >90%
 
Plano surface/bottom:
40-20S/D; <lambda/4 @633nm over surface; Clear aperture: >90%
