basic information
Iridian Spectral Technologies' wide-angle long-pass filters offer excellent edge steepness and high blocking performance, allowing for easy spectral separation by transmitting or reflecting wavelengths around the specified wavelength. With an angle adjustment range of 0 to 2 degrees, positioning adjustments have also become easier. This is particularly useful for Raman spectroscopy measurements that require the separation of Rayleigh scattered light (laser wavelength) and weak Raman scattered light. In addition to Raman spectroscopy, these filters are ideal for integration into optical measurement systems such as confocal microscope systems. The hard-coated product lineup provides significantly superior optical characteristics compared to traditional soft-coated filters, along with longer lifespan and high durability.
