ZPS – Zero Pixel Shift Filters
Enable fluorescence microscope imaging at multiple visible wavelengths with near-perfect image registration.
Advances in fluorophores and sources are driving wider use of multi-color microscopy. Coherent draws on our advanced coating expertise to offer filters with no wavelength walk-off. ZPS are ideal for excitation and emission as well as dichroic beamsplitters.
ZPS – Key Specifications Summary
Superior coating flatness and precise mounting eliminate pixel shifts due to wavelength and filter exchange.
