The steady advances in optical thin film deposition technology over recent decades have enabled production of high performance multiband optical filters that address the increasing demand for multicolor fluorescence instrumentation. Though there is now a wide range of available catalog filters designed for a large variety of fluorophores, selecting suitable filters is often a complex process. Here we present considerations relevant to the design of such a multiplexing system. Learn More
Any imaging instrument has a limited tolerance for wavefront error – and every optical element in the light path (including dichroic beamsplitters) contributes to wavefront error, thereby limiting overall imaging system performance. When aiming to achieve diffraction-limited imaging performance or better, it is important to consider wavefront errors from all optical elements in order to calculate the total instrument wavefront error, and to compare it to the maximum allowable value.

Fluorescence occurs when a molecule absorbs light at wavelengths within its absorption band, and then emits light at longer wavelengths within its emission band. For example, brightly fluorescent molecules (called fluorophores) can be attached to biologically significant molecules in e.g. cell membranes, in the brain, or even on subunits of DNA, whose structures become visible in a fluorescence microscope that allows us to track the way cells function in health and disease. Fluorescence is widely used in biology, biotechnology, and medicine, due to its extraordinary sensitivity, high specificity, and simplicity of usage.
