Filters

Ealing offers a wide range of optical filters using a variety of materials and techniques in order to provide a range of solutions that will allow you to select the most cost effective solution for your application. The applications include laser combining or separating, color temperature correction, laser attenuation, imaging, microscopy, cytometry, spectroscopy just to name a few. The selection of the most appropriate optical filter depends on a number of key criteria such as spectral transmission and rejection at various wavelengths, blocking characteristics, peak transmission, angle of incidence, temperature, size and mounting requirements.

Ealings range of filters include bandpass filters, edgepass filters, color glass filters and neutral density filters.
