High precision diameter 1mm 2mm Optical Glass Crystal Bk7 Fused Silica Ball Lens
DESCRIPTION
Ball lenses are a completely spherical lenses most commonly used for improving signal coupling between fibers, emitters and detectors. Aside from fibre coupling applications, ball lenses are also used as objective lenses in endoscopy, laser measurement systems and bar-code scanning. Ball lenses are manufactured from a single substrate of glass and can focus or collimate light, depending upon the geometry of the input source.
FEATURE
- Easily positioned
- High diameter tolerance and spherisity
- Excellent surface roughness
APPLICATION
- Optical Measurement Systems
- Projection Optics Systems
- Imaging Optics Systems
- Astronomical Optics
