NOTE: Photon etc. reserves the right to change the design and specification of the product at any time, without notice.

*** Valid if the divergence of the input beam does not exceed 1 mrad.

****  To reach this specification in free space configuration, it is required to couple the filter with Photon Etc.’s background suppressor accessory. Contact us for more details.

Applications

THIN FILMS OF GaP

Spectral dependence of the Faraday MO effect with temperature dependence measurements were performed on a semiconductor 2 µm epilayer (GaP) grown with embedded metallic ferromagnetic nanoclusters (MnP).

SWNT BREATHING MODES

Two narrowband tunable filters for resonance Raman spectroscopy (RRS) were designed to study the radial breathing modes of carbon nanotubes.
