There are many factors taken into consideration during the development of a valve design. Prototyping the complex geometries of valve stators can be expensive and time-consuming but with the use of simulation tools, we can iterate multiple designs quickly and select the most desirable solutions before the first parts are manufactured.

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.

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. Learn more in this white paper.

While most applications call for optical filters to be used at normal incidence, it is important to understand how the spectral properties of different types of filters change when using these filters a non-normal angles of incidence (AOI). There are two main effects exhibited by all filter spectrum as the angle is increased from normal which are discussed in this article.

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. Learn more about what optical filters are included in a fluorescence instrument and how Semrock optical filters can optimize your application.

Laser damage to optical filters is strongly dependent on many factors, and thus it is difficult to guarantee the performance of a filter in all possible circumstances. Nevertheless, it is useful to identify a Laser Damage Threshold (LDT) of pulse fluence or intensity below which no damage is likely to occur. Laser damage may be broadly classified into two types: absorption-driven and dielectric-breakdown damage. Which type dominates depends on the material properties (absorption coefficient, specific heat, melting temperature, as well as defects that cause scattering and concentrated electric field effects), geometric properties of the sample (thickness, homogeneity, surface morphology, etc.), and of course the properties of the laser beam itself.
