Features:

nnnn

• Ultra narrow rejection bandwidth

nnnn

• Highly repeatable performance

nnnn

• Environmentally stable at high temperature

nnnn

and humidity

nnnn

• No degradation overtime, even under high

nnnn

power illumination conditions

nnnn

Ondax's SureBlock™ ultra narrow-band notch filters are the ideal

nnnn

solution for highly selective wavelength applications like low

nnnn

frequency Raman spectroscopy. With laser line attenuation greater

nnnn

than 99.99% (optical density: OD 4) and spectral transition width of

nnnn

<10 cm"1, SureBlock™ filters can dramatically improve the ability of

nnnn

any Raman system to resolve low frequency Raman scattering. High

nnnn

transmittance on both sides of the notch enables both Stokes and

nnnn

anti-Stokes Raman spectra to be observed simultaneously.

nnnn

Individual filters are mounted in 1" housings for compatibility with

nnnn

standard 1" optical systems. Alternatively, our SureBlock™ XLF Filter

nnnn

System integrates two notch filters into a rugged, pre-aligned, light-

nnnn

tight enclosure with free space or fiber input & output.

nnnn

Available at standard Raman wavelengths: 488, 514,532,633,78Xnm.

nnnn

Custom wavelengths are available on demand.
