Product Description

Name:
--Germanium (Ge) is a relatively hard, high-density, IR transmitting material that blocks UV and VIS wavelengths but allows IR from
2µm. Germanium has the highest refractive index of commonly available IR-transmitters and has low optical dispersion. This makes
it desirable in aspects of lens design where its refractive index allows otherwise impossible specifications to be built.

 

 

Ge Longpass filters

--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.
