holoOPTIX® STRATA is a range of holographic notch filters in industry standard 1” diameter form factor. These filters offer narrow, high optical density stop bands paired with high transmission in the pass band.
This makes them ideally suited to blocking laser sources in fluorescence or Raman spectroscopy instruments.
This holoOPTIX® STRATA 635nm, 1″ volume holographic grating is protected within a glass sandwich structure. All air interfaces have a broad band antireflective coating to maximize the out of band transmission. The wavefront distortion of transmitted beam is less than 1λ at 633nm.
The notch wavelength can be tuned by adjusting the angle of incidence. As the angle of incidence is increased, the notch center will blueshift to lower wavelengths. This allows a single notch filter to be used to block a range of wavelengths. Unlike typical dielectric notch filters, the notch center wavelength is the same for p- and s- polarization, even at high angles of incidence.
