Hamamatsu Photonics’ PMA-12 C10027-01 is a compact spectral measurement system that couples an optical detector and a spectrometer into a single unit. Due to the high sensitivity, spectra can easily be acquired in numerous applications, simply by moving the optical fiber near the sample without the need to connect to an exclusive light collection system.

The photo-detector and spectrometer are built with high machine accuracy, making the PMA-12 stable and enabling it to be used for extended periods. The wavelength axis and spectral response features are factory-calibrated, so spectral measurements can be performed in an accurate and effortless manner.

The C10027-01 spectral measurement system is an ultrahigh sensitivity model (200–950 nm).
