Applications

  • Emission Filters in Fluorescence Applications
  • Order Sorting Filters for Photometry
  • Stray Light or Trim Filters to Eliminate any Unwanted Near Band Radiation
  • Raman Spectroscopy Filters
  • Astronomy Applications

Thorlabs' Edgepass Filter Kits each contain 10 mounted longpass or shortpass filters for isolating regions of the visible or IR spectrum. Each filter is mounted in an unthreaded Ø1" black anodized aluminum ring that can be placed into our selection of filter mounts or  Ø1" lens tubes using retaining rings. The filters are packaged in a metal storage box. Detailed specifications can be found in the table below.

Our edgepass filters are constructed of durable dielectric coatings and will withstand the normal cleaning and handling associated with any high-quality optical component. Their film construction is essentially a modified quarter-wave stack, using interference effects, rather than absorption, to isolate their spectral bands. Thus, unlike colored filter glass, the cut-off/cut-on wavelength will be shifted to shorter wavelengths with an increase in the angle of incidence. This feature can be useful in applications where it is desirable to fine tune the location of the cut-on or cut-off wavelength. Our edgepass filters are hermetically sealed for maximum humidity protection and may be combined for custom bandpass filters.

To inquire about our custom edgepass filter options, including the possibility of alternative cut-on or cut-off wavelengths, please contact Tech Support. Please note that there is a significant lead time and tooling cost associated with custom filters that makes the purchase of only a few pieces fairly costly.

Response from Javier at Thorlabs to t6669036: there are two methods that you can use to safely clean your filter. The first method is the drag method: -Blow off any superficial dirt and dust with compressed air (CA3) -Place a kimwipe on the optic and pour a generous amount of reagent-grade isopropyl alcohol or acetone and slowly drag the tissue uniformly across the surface of the mirror -The solvents should then evaporate without leaving any spots or streaks The second method is very simple. You can use cotton tipped applicators along with isopropyl alcohol or an optical cleaner such as the FCS3 (same page as CA3), and gently run the applicator in a circular pattern throughout the surface of the optic. I hope this helps.

I want to know the proper way to clean this filter. My filter is dirty and Im afraid if I didnt clean it properly it will be damaged. Thank you very much and looking forward to hearing from you soon.
