Spectroscope

• Polychromator architecture with in-house InGaAs PDA
• Fixed diffraction grating offers robust configuration
• Architecture has no moving parts which enables the module to be compact, highly reliable, and to achieve high-speed measurement.

• High resolution ( 1 pm) is achieved by a unique interpolation algorithm from pixel data.

The center wavelength of an FBG spectrum is calculated through interpolation of pixel data, which allows a wavelength display resolution of 1 pm. Number of simultaneously measurable FBG sensors is 40 (typical, depending on FWHM and pitch (max. 100 FBGs)).
