Precise Infrared Filtering for Professional Optics
This 780nm infrared long wave pass filter allows light with wavelengths greater than 780nm to pass through while blocking shorter wavelengths. Its steep cut-off and high transmittance ensure clear, accurate imaging in your infrared optical systems.
Ideal for IR camera lenses and spectroscopy, the filter enhances image clarity by eliminating unwanted light interference outside the targeted infrared range.
Reliable Optical Performance and Material Quality
Made from durable acrylic with anti-reflective coating, this filter delivers excellent transmission with a wavefront error of λ/4 at 780nm. Its optical properties include a cut-off band steepness of 90% and a cut-off zone depth of OD4.
The filter is round with diameter options from 10mm to 58mm and a consistent thickness of approximately 1.0mm, ensuring compatibility with various imaging devices.
Applications Across Spectroscopy and Imaging
Use this filter in fluorescence excitation spectroscopy, Raman spectroscopy, spectral grouping, astronomical observations, and machine vision systems.
It effectively improves system sensitivity by filtering out interfering wavelengths and enhancing signal quality in scientific and imaging contexts.
