Optical Filters For Raman Analysis:  Finding The Needle In The Haystack
Optical Filters For Raman Analysis: Finding The Needle In The Haystack Fundamental to most Raman microscopy applications is the desire to access as much of the Raman fingerprint of the molecule of interest as possible, requiring filters that provide “more signal with less background.” In order to optimize the capture of this very-low wave number Raman signal, a premium is put on edge pass filters with extreme steepness, very precise edge wavelength control, and deep blocking of the excitation laser.  Continue Reading...

HOT PRODUCTS

  • Optical Filters For Flow Cytometry
    Optical Filters For Flow Cytometry

    Iridian Spectral Technologies designs and manufactures optical filters that are optimized for flow cytometry. These dichroic (FLD) and emission (FLE) filters deliver more signals with less background noise, and are compatible with common excitation sources and fluorophores. They also feature high transmission and reflection levels, low ripple, steep edges, and deep blocking outside of the pass band.

  • Imaging Color Filters
    Imaging Color Filters

    Iridian Spectral Technologies has designed and manufactured a wide range of dielectric optical filters for imaging and machine vision applications. Featuring steep edges, high transmission values, and high durability, these color filters can be used to improve contrasts, and isolate spectral regions and colors in images.

  • Optical Filters for Endoscopy and Medical Imaging
    Optical Filters for Endoscopy and Medical Imaging

    Iridian Spectral offers edge, notch, and band pass optical filters covering the 300nm (UV) to 10µm (LWIR) wavelength range for biomedical instrumentation, and medical devices for endoscopy and laparoscopy.

  • Fluorescence Filters
    Fluorescence Filters

    Iridian offers excitation, dichroic, and emission fluorescence spectroscopy filters for confocal microscopy, flow cytometry, and other biomedical applications. These three different filter types are often used in a set in order to maximize the desired signal while minimizing the undesired signal.

  • Raman Filters
    Raman Filters

    In Raman spectroscopy applications, emitted light is very close in wavelength range to the excitation light. In order to attenuate a laser’s signal from reaching the detector while at the same time transmitting the weak emitted light signal, notch or edge pass Raman filters are required. Because of their high transmittance and extended deep blocking, Raman laser line filters are also required to ensure that only the desired wavelength is actually illuminating the sample being tested. This page provides an overview of Iridian Spectral Technologies' line of filters for Raman spectroscopy.

  • Telecom Filters
    Telecom Filters

    Iridian Spectral Technologies ships anywhere between 10,000 to 40,000 telecom filters per week.
