This introduction to diffraction gratings guides us through the various types of gratings and understanding their advantages and disadvantages as well as some useful grating equations.

Total internal reflection fluorescence (TIRF) microscopy is used to watch biological processes unfold in real time. Taking advantage of the ability to label individual molecules with different colors of fluorescent tags, TIRF microscopy lets scientists view the complex molecular assemblies that govern cellular processes.

Considerations when specifying transition pass bands, blocking bands, and transition widths include filter manufacturing tolerances, thermal tolerances, and source/detector variations. These factors must be taken into account properly and completely to achieve optimal spectral performance.

In laser seam welding, a galvo scanner helps expand the laser source’s effective fine spot size to the seam width, lays a complex welding pattern over the motion path to create high-quality welds, increases throughput, and takes advantage of higher-power laser sources.

Abrisa offers solutions that promote color or signal separation, signal and “color” isolation, color temperature correction, aesthetic lighting effects, selective wavelength or color illumination, dichroic color separation, and filters for heads-up displays (HUD).

With speeds of over 1 million frames per second, high-speed imaging is an invaluable research tool capable of capturing the most fleeting events in scientific and engineering applications. Yet achieving this speed comes with strings attached.
