1427 nm ... 1608 nm calibration of PM1000 polarimeter

The PM1000 polarimeter is now available with calibration not only in L and C bands but also down to 1427 nm, thereby covering the important pump wavelengths. Total optical frequency range is about 186.4 ... 210.1 THz. With another polarimeter head the PM1000 works around 1310 nm. Ask us for your needed wavelength calibration range!
