Spectrograph VPH
Product description
This Raman spectrometer is integrated with a high throughput spectrograph (Omni-iSpecT) that is designed for high resolution and high speed raman imaging. The Omni-iSpecTM has two models to accommodate different requirements: lasers, wavelength and spectral resolution.
The Omni-iSpecTM is a very good solution for collecting more light and achieving better S/N ratio. The high light collection efficiency capabilities of Omni-iSpecT spectrograph combined with ultra-sensitive CCD detectors offer the most versatile and sensitive detection solution for VIS & NIR applications. Its rugged and compact design makes an ideal module for in-the-field and industrial applications. It is still suitable for academic research with research-grade performance. The Omni-iSpecTM also provides the SDK file for secondary development.
