Customized Filters for Spectral Analysis II

Steep-Edge Long Pass Filters

Steep-edge Long Pass Filters provide very steep cut-on slope, deep rejection and high transmission at the same time. These filters are made by using dielectric thin films only without employing any absorbing filter glasses. Custom cut-on wavelengths and custom sizes are available on request. Sharp transition is useful for separation of exitation light and emission in various spectral analysis including fluorescence analysis.
