1The calibration markers listed are produced by a HeNe laser incident on the small calibration gratings. Use of a different calibration light source having a different wavelength will produce markers (see Fig. 4) coinciding with different values of the dispersed spectra of the four primary gratings. Using a common input angle for calibration light and signal， the calibration marks delineate spectral output ranges of the primary gratings that are independent of grating input angle.

2 For orders with the total product value below $250.00， a handling charge of $75.00 will be added.
