Product Description

Spherical biconvex lenses of BK7 are mostly used for monochromatic lights, such as laser beams or Fraunhofer lines. They are useful when lights from point sources are converged or images are relayed to other optical systems.

The lenses are polished carefully by selecting materials (striae, bubbles, inclusions, and homogeneity) and paying attention to dispersion (digs, scratches, and glosses) to prevent troubles with coherent light

Uncoated and coated with broadband multilayer AR coatings for visible are available.
