plane parallel plates

plane parallel plates


The plates are characterized by a high flatness of the surfaces and by a constant optical thickness over the entire aperture. They can be used as windows as substrates for beamsplitters in interferometers or as solid etalons.

We offer plane parallel plates either made of crown glass N- BK7 or of synthetic fused silica.

The plates are not coated by default.
