SCHOTT-Filter Calculator Program

Online-transmission-calculator for all SCHOTT optical color glass filters


Our online SCHOTT-filter calculator allows you to individually calculate and analyze the transmission curves of nearly all SCHOTT color glass filter materials. This makes it easy to find out the best optical color glass filter for your individual application. This useful tool is provided to you for free.



Calculation Parameters

Select filter type:

Enter filter thickness:

mm ?Please enter the desired filter thickness here. Please consider, that it is not recommended to choose filter thicknesses below 1mm, because the compliance with the transmission specifications of the material at lower thicknesses isn't safe anymore.                                                 

Transmission curve output:

Spectral transmission ?Choose this option to see the transmission under real world conditions: This option includes surface reflection losses based on a single filter used in air.                                                        
(Surface reflection losses included)
Internal transmission ?Choose this option to see the internal transmission of the filter. This option does NOT consider the surface reflection losses which under normal conditions occur. The internal transmission is important to know for the design of cemented filter combinations.                                                        
(Internal transmittance, surface reflection losses NOT included)
Best scale factor for transmission axis (Y-axis zoom) ?This option allows the automatic best scaling depending on the max. transmission within the measuring range. If for example a max. transmission of 10% is reached within the measuring range, the Y-axis which is the transmittance will be scaled to a value range of 0-10%. This allows a more exact analysis of the transmission in wavelength ranges with lower transmissions.
