Highly Efficient Tunable Filter for Broadband Light Source

Author: Jun Hee Kang Sunday, September 1, 2019
A new, simple and compact approach for tunable wavelength filtering is introduced with a device called Flexible Wavelength Selector. 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 high transmission efficiency, circular round aperture of up to 10 mm and independent tuning of center wavelength and bandwidth. More white papers
