Achromats for fs-Pulses

fs-Achromate/Zeichnung(4k)

Twin lens air spaced achromats (Fraunhofer achromats), back focal length achromatized at 790 nm, corrected for constant pulse propagation time (vs. aperture) for fs pulses with 790 nm.
An achromat with negative focal length is available for the setup of laser beam expansions without focus.
The lenses are coated with broadband multi layers for the spectral range around 790 nm.
We have available for this objective a drawing of the holder dimensions with some additional data about integration.
