Lame Séparatrice, 90/10

Numéro de référence fabricant :


Fabricant Ondax


Description :

Ondax's NoiseBlock™ 90/10 Beamsplitter Filters are designed to diffract 90% of the incoming light that matches the designed Bragg wavelength (λ0) and incident angle. All other wavelengths will be transmitted through the filter, making them excellent for boosting the effective signal of a Raman spectrometer. Adding a NoiseBlock™ 90/10 beamsplitter filter to a Raman spectrometer with a wavelength stabilized laser source can increase the recovered Raman signal by almost a factor of 4 relative to a broadband 50/50 beamsplitter.
