Ealing has a wide selection of standard mirrors for research and OEM use in a variety of materials, forms, sizes and quality levels. The selection includes broadband dielectric mirrors, aluminum mirrors made from BK7, Fused Silica, Pyrex and Crown glass. They are used throughout the Ultraviolet, Visible and Infrared spectral regions as beam steering components, imaging optics, collimators, condensers and light collectors. Our broadband beamsplitter plates are made from high quality BK7 laser quality substrates and are designed to work at 45 degrees incidence. The Ealing beamsplitter cubes are non-polarizing elements consisting of two right-angle prisms cemented at their hypotenuse faces producing equal reflection of both the s and p polarization states of a laser beam.
