Achromatic Objectives for fs-Pulses

Achromatic Objectives for fs-Pulses

The achromatic doublet lenses with air gap (Fraunhofer achromats) are designed for a constant back focal length in the spectral range around 790 nm. This yields a constant propagation time for fs pulses over the entire aperture at this wavelength. The lenses are broadband antireflection coated.

Chromatic Focal Shift

Achromatic Objectives for fs-Pulses

The graph shows the typical relative spectral shift of the focal length referenced to the nominal focal length f for objectives of this series. To calculate the shift in length units for a certain objective the values must be multiplied by the respective nominal focal length.
