Paper Abstract

A new, simple and highly efficient approach for tunable wavelength filtering is evaluated with a motorized angle dependent tunable filter. This new device combines the flexibility of a monochromator with the imaging functionality of a thin-film interference filter, and is ideal for use in both illumination and image acquisition in optical microscopes. The main features include independent tuning of center wavelength and bandwidth, high transmission efficiency and circular round aperture with high damage threshold.
