Line.jpg (6918 bytes)

 

  • Popular lenses conveniently organized by focal length
  • Edged marked lenses allow easy identification
  • Available in 1 and 2 inch diameters
  • Master and starter kits offer complete and partial lens selection
  • Wide range of standard focal lengths from 26 to 1000mm

For applications where multiple focal length lenses may be needed, BK-7 lens kits provide a convenient selection of equivalent diameter lenses from which to choose.  Each lens comes with an edged marked label to help identify its focal length.  BK-7 lens kits are available in Master and Starter configurations.   Master BK-7 lens kits contain a complete selection of 50 one inch diameter lenses or 44 two inch diameter lenses.  The starter BK-7 lens kits offer an economical selection of 27 popular one inch diameter or 24 two inch diameter focal lengths. 

The focal lengths of the lenses in the one inch and two inch Master and Starter kits are listed in the tables below.  All BK-7 lens kits are offered with either broadband or narrowband laser line anti-reflection coatings in the UV, visible and near IR spectral regions.  Uncoated lens kits are also available.   All lenses are elegantly arranged in a foam inlaid hardwood box that may be used for permanent storage.
