GE IS200TSVOH1B Multiplexer switch module

Photodiode detectors are inherently very linear but also have a large variation in sensitivity with wavelength. In addition, most sensors from the Ophir PD300 series are equipped with both a built in filter and removable filter to allow measurement of higher powers without detector saturation. These filters also have a transmission that depends on wavelength. Therefore, when the PD300 is being used with the Nova II, the Nova II has a built in calibration adjustment for wavelength which is described in the next paragraph.

Method of Factory Calibration 

The sensitivity of various Ophir photodiode sensors can vary from one to another as well as with wavelengths. Therefore, Ophir photodiode detectors are individually calibrated against NIST traceable standards over the entire operating range of wavelengths for both filter out and filter in. The calibration curve is normalized to the correct absolute calibration at 632.8 nm using a HeNe laser against a reference meter traceable to NIST.
