Any standard Optometrics grating is available with either P-type or CW-type construction or higher damage threshold performance.
Damage Thresholds: (no damage threshold minimums apply to gratings with an overcoat)
Standard Replica Gratings:
Pulsed - 350 milli-joules/cm2 @ 200 n sec.
CW - 0 watts/cm2
P-Type Replica Gratings: (pulsed type)
Pulsed - 3.5 joules/cm2 @ 200 n sec.
CW - .80 watts/cm2
CW-Type Replica Gratings: (for continuous high power applications)
Pulsed - 3.5 joules/cm2 @ 200 n sec.
CW - 250 watts/cm2
Coatings
Regardless of size, the additional cost per piece is:
Gold Overcoat (AU3) - $60.00
Aluminum Magnesium Flouride (ALMG-3) - $55.00
Note: while a gold overcoat can increase reflectivity, any overcoating may reduce the damage threshold by a factor of two or more.
