Using three ruling engines in a controlled environment, Optometrics can rule polarisers with groove spacings up to 1200 per mm. Optometrics manufacture ruled polarisers by ruling precisely spaced grooves directly into high polished CaF₂ or ZnSe substrates. The ruling process forms sharp, well defined peaks which are then coated with aluminum at an oblique angle, resulting in a series of closely spaced, highly conductive wires with a high extinction ratio and an inherently high damage threshold, allowing the use of the ruled polarisers with relatively high power lasers. Typical damage thresholds are 100 W/cm² CW and 2 J/cm² pulsed.
