Press Release Summary:
Useful for FTIR spectroscopy and thermal imaging applications, Infrared Longpass Filters provide sharp cut-off below particular wavelength and are often used for order sorting. Units simultaneously provide high transmission of desired energy and deep rejection of unwanted energy. Constructed with hard first-surface dielectric coatings on optical-quality IR-transmitting substrates including sapphire, silicon, and germanium, filters withstand normal cleaning and handling.
Original Press Release:
Infrared (IR) Longpass Filters
o Ideal for Isolating Broad Spectral Regions
o Sapphire, Silicon, and Germanium Substrates
o Durable, First-Surface Coatings
Longpass filters provide a sharp cut-off below a particular wavelength. Often used for order sorting, they isolate broad regions of the spectrum, simultaneously providing high transmission of desired energy, and deep rejection of unwanted energy.
Constructed of hard, durable first-surface dielectric coatings on optical-quality IR-transmitting substrates, these Infrared (IR) Longpass Filters will withstand normal cleaning and handling associated with any high-quality optical component. These filters are particularly useful for FTIR spectroscopy and Thermal Imaging Applications. For custom sizes and coating requirements, please contact us.
