OtO Photonics releases the Phekda (PD-series) ultra-high-resolution general-purpose micro-spectrometers, featuring a T-R-T (transmissive-reflective-transmissive) optical design with resolutions up to 0.1nm to address the needs of ultra-high-resolution measurements under narrow wavelength ranges. The innovative T-R-T design provides the flexibility of highly customizable wavelength ranges. You can choose the range in the VIS or NIR (within limits of 400 – 1000 nm or 900 – 1700 nm) to fit the specific needs. The PD-series is used in various applications such as optical coherence tomography, laser induced breakdown spectroscopy (LIBS), VCSEL source characterization, and Raman spectroscopy.
