If the grating you require is not shown above, please contact our sales department as new gratings are added on a regular basis. Alternatively we can manufacture custom gratings to your specification.

Please Note: Grating efficiency curves are indicative only and may vary from master to master. Efficiency may also vary depending on measurement technique and geometry of use.
