In a Nutshell

High End Aspherics

• A New Series of Aspheric lenses.
• These lenses  offer regular performance with a slightly  relaxed tolerance in the aspheric surface.
• Allowed deviation now < 0.25 µm RMSi compared to < 0.05 µm RMSi for the High End Aspherics.
• The allowed wave front deviation is about 1 wave at the laser wavelength.
• All other tolerances are compatible to the precision series.

In a Nutshell

• The use of aspheric lenses in optical systems, focusing optics and laser optics, is  increasing.
• They enable enhanced resolution especially for optical systems with a high f-number.
• The aspheric deviation of the high end series is < 0.05 µm RMSi.
• Special forms and customized versions are available on request.
