1.8mm 2mm BK7 half ball lens 

1.8mm  2mm BK7  half ball lens Ball lenses are great optical components for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications. Ball lensesare manufactured from a single substrate of glass and can focus or collimate light, depending upon the geometry of the input source. Half-ball lenses are also common and can be interchanged with full ball lenses if the physical constraints of an application require a more compact design.   Specifications: Material: BK7/K9,Fused Silica,Sapphire,Silicon, Znse and LaSF7 glass or other optical glass upon request Sphericity: ,3um Surface Quality: 60/40 Diameter: 1.8mm, 2mm, 3mm, 4mm 10mm upon request More Information as choice ZnS aspheric lens Germanium IR lens Germanium Plano Convex Lens Spherical Concave Mirror Curved round Mirr…
