plano-convex and plano-concave lenses in the diameter range 10 - 60mm 

     Paraxial focal distance /f/

     ± 5%

     Diameter

     ± 0,25

     Refraction index /n/

     ± 0,001
 

     Material

The plano convex lenses are widely applied in telescopes, collimators, transport system, condensers etc.
The plano concave lenses are largely applied in telescopes, 
in conjunction with plano convex lens they form a Galilean system suitable e.g. for laser been enlargement.
Further on they are used wherever a divergent beam is required without a real point of concentration.

On request we are ready to manufacture optical elements of other dimensions,
surface quality and accuracy according to the drawing of clients.
