This excitation filter is designed specifically for use in fluorescence imaging applications. The Ø25 mm filter is mounted in a black anodized housing that is 5 mm thick. The engraved arror indicates the recommended light propagation direction.

These Filters are manufactured to high-performance optical specifications and designed durability. They are produced with multiple dielectric layers deposited on a high-precision, fused silica substrate. The substrate is ground and polished to ensure that the highest possible image quality is maintained. These Hard-coated optics produce filter layers that are denser than those obtained from electron beam deposition techniques. The dense filter layers reduce water absorption and greatly enhance durability, stability, and performance of the filter. Each layer is monitored during growth to ensure minimal deviation from design specification thickness, ensuring overall high-quality filter performance. All filters conform to MIL-STD-810F and MIL-C-48497A environmental standards.
