PRODUCT NOTE<br />

Fluorescence Imaging of the Formaldehyde Spectrum<br />

<strong>Semrock</strong> is known for its spectrally complex filters, including the<br />

world’s only five color multiband filter set. Faced with the challenge<br />

of improving the fluorescence signal of the formaldehyde spectrum,<br />

<strong>Semrock</strong> designed an 11-band bandpass filter optimized to<br />

capture the peaks of formaldehyde emission over the 380 – 480<br />

nm wavelength range. Formaldehyde (CH 2<br />

O) is an ideal chemical<br />

for use in laser-induced fluorescence (LIF) when excited at 355 nm.<br />

This research techinique is most commonly used to investigate the<br />

homogeneous charge combustion ignition (HCCI) combustion process.<br />

The graph shows the measured spectra of the 11-band filter designed<br />

for imaging formaldehyde, overlaid with the emission spectra of<br />

formaldehyde. Note the nearly ideal overlap and high transmission of<br />

this filter. Blocking was incorporated into the filter design for the full<br />

visible and near IR spectrum.<br />
