Optical Filters 

Inphora offers calculation, design and production of unique optical glass filters matched to the customer’s requested parameters or to fit  a specific application. Inphora is a leader in the design and production of all-glass filters.  All-glass filters have significant advantages over thin film designs including longer life, long term spectral stability, insensitivity to temperature, and a wider field of view. Our filters have excellent surface and internal quality with the ability to hold to very tight scratch/dig specs. Inphora optical filters provide reliable quality you can count on.

Photometric Glass Filters

 

  • CIE V(λ) function sensitivity.

  • Filters are matched to a spectral sensitivity function provided by the customer (Si photocell, CCD camera or other type of detectors)

  • Diameter and thickness can be adapted to the customers specific application.

  • AR coating may be added.

  • Edges may be painted black to block light from entering from the side.

Colorimetric Glass Filters

 

  • CIE tristimulus function sensitivity.​

  • Available in sets of X, Y, Z or X1, X2, Y, Z bars.

  • Filters are matched to a spectral sensitivity function provided by the customer (Si photocell, CCD camera or other type of detectors)

  • Diameter and thickness can be adapted to the customers specific application.

  • AR coating may be added.

  • Edges may be painted black to block light from entering from the side.

Radiometric Glass Filters

 

  • Uniform sensitivity within a given spectral range.

  • Available in neutral density (ND0, ND1, ND2, ND3, ND4), IR cut-off, and IR pass.

  • Diameter and thickness can be adapted to the customers specific application.

  • AR coating is standard.

  • Edges may be painted black to block light from entering from the side.
