UV Plate Polarisers
Thin
film plate polarisers are one of the best ways of creating a highly polarised
output while handling the high energy UV sources.
The film consists of a stack of reflecting surfaces, each of which
polarizes the incident radiation by reflective polarisation and must be used at,
or close to, the Brewster angle for UV Fused Silica (56°).
The
reflected beam contains only s-polarised light and the p-polarised component is
transmitted. Thin film plate
polarisers produce an extinction ratio in excess of 100:1 and they easily handle
energy levels of 5 J/cm2 (10ns).
These
polarisers are produced on highly polished substrates of UV Fused Silica.
They are circular or rectangular in shape—typical sizes are 25.4 and
50.8 mm diameter or 28 x 14 mm rectangles.
We
can supply high power thin film UV plate polarisers for the following
wavelengths: 248, 266, 308, 355 nm
