Substrate Material Code CC	Substrate Material
AL	Aluminum
BF	Borosilicate float or equivalent
BK	BK-7 glass or equivalent
CU	Copper
FL	Float glass
FS	Fused silica or equivalent
LE	Low-expansion glass
SP	Special glass (unspecified)
TB	BK-7, transmission grade
TF	Fused silica, transmission grade
UL	Corning ULE® glass
ZD	Schott Zerodur®
Coating Type Code DD	Coating Material	Application
01	Aluminum (Al)	General purpose applications.
02	Gold (Au)	Offers higher reflectivity in the infrared.
03	Magnesium Fluoride on Aluminum (MgF₂on Al)	Prevents oxidation of aluminum coating, which helps maintain high reflectivity in the ultraviolet over time.
06	Protected Silver (Ag)	Offers higher reflectivity in the visible and near infrared. Silver is protected from tarnishing by a dielectric coating, which helps maintain reflection over time.
09	Silicon Dioxide on Aluminum (SiO₂on Al)	Prevents oxidation of aluminum coating, which helps maintain high reflectivity in the ultraviolet over time.
Master Grating Code EEEx	Master Grating Type and Groove Parameters
420H	Plane holographic, 2400 grooves per mm, 270 nm nominal blaze wavelength (1^storder Littrow), 200 nm - 800 nm recommended spectral region

Newport is pleased to discuss special and unusual applications that are not addressed by our build to order catalog diffraction gratings. In some instances, none of the hundreds of master gratings we have in stock meet specifications, so a new master may be required. Please see Custom Diffraction Gratings for additional information on our capabilities.
