3D Confocal Raman and Photoluminescence Spectrophotometer
The Nanofinder30 Raman spectrometer is designed for advanced spectroscopic analysis for both Raman (vibrational signatures in materials) and steady-state photoluminescence (i.e. fluorescence). It comprises an upright microscope with a range of standard objective lenses (20x to 100x), optical systems for both visible and near-infrared (NIR) spectra, and an imaging spectrometer with multiple gratings for precise spectral resolution. Equipped with a cooled CCD detector and laser scanning unit, the spectrometer enables high-sensitivity detection and XY scanning of samples within the field-of-view.
The Nanofinder30 features laser sources such as a continuous wave (CW) solid-state laser at 532nm and a CW NIR laser at 785nm, each offering high power outputs for Raman excitation. For near-infrared photoluminescence (PL) detection, the system employs a cooled InGaAs detector and a dedicated NIR objective lens.
The system is also equipped with a microscopy cryostat system, enabling measurements at cryogenic temperatures as low as 4-5 K.
New updates include a motorized stage for x-y positioning of the sample, and a Linkam heating and cooling stage -192 C to 600 deg C.
