This page provides access to transmission spectra for round dichroic mirrors we have in the lab (most are 25 mm diameter). Spectra are organized into three categories based on the type of dichroic mirror: BP (Bandpass), SP (Shortpass), and LP (Longpass). Spectra files are named using a lineshape analysis program that locates regions above 50% transmission and creates the file name by concatenating the center and FWHM of each region to the dichroic index number of the optic in the library. Example name: D20_450-80_BP, indicates dichroic #20 with a transmission peak center wavelength of 450 nm and FWHM of 80 nm in the BP (Bandpass) category.

To view a spectrum, select a file from the dropdown menu for the desired category and click "Plot".
