1 The peak efficiency wavelength, λPE, indicates wavelength(s) of highest efficiency at 1st diffractive order for a given polarization state (in parenthesis). S (P)-polarization: Incident electric field vector parallel (perpendicular) to grating lines. Values are given for Littrow mount.
2 Second dimension corresponds to the groove length.
3 For orders with the total product value below $250.00, a handling charge of $75.00 will be added, otherwise the handling fee is $5.00.
4 Example of price calculation for 200 unit order: $60*99 (first 99 units)+ $25*101(100+ units)=$8,465.00
