Note a: LP1 heads have relatively large spectral variation in absorption and have a calibrated spectral curve at all wavelengths in their spectral range. When used with the Nova II (software v 1.59 and above) or USBI (V 1.17 or above) supporting this feature, accuracy is ±3% for any wavelength from 250 to 2200nm. When used with displays not supporting this feature, accuracy will be ±3% for wavelengths 532nm, 755nm, 1064nm and 2100nm and ±6% for other wavelengths in the spectral range 400 – 1100nm.
