Abstract
Low-loss and broadband optics is important in optical measurement and
imaging. Here, we design an axicon-based beam shaper for low-loss and
broadband microscopic optics by numerically calculating the
transmittance and focusing performance, assuming an application to
stimulated Raman scattering (SRS) microscopy. Furthermore, we
demonstrate the beam shaper equipped in an SRS microscope and confirm
that the axicon-based optics increases transmittance without
sacrificing spatial resolution or signal intensity.
