This automated wavelength tuning can be used to acquire
near-simultaneous microscope images of multiple fluorescent
labels (see Fig. 3). This simple example shows HeLa cell images optimized for DAPI and Dil. This type of imaging would
normally require either some type of filter
wheel or else multiple cameras, each with
a different bandpass filter.
In another very different application example (see Fig. 4), a
dramatic difference can be seen between the visualization of vessels in a hand viewed under normal white-light conditions and
via custom TwinFilm spectral filtering optimized by the user.
This is valuable because, from drawing blood to avoiding minor blood vessels during inoculations and in aesthetic procedures, there is a clear need for the sur-
geon or nurse to visualize blood vessels, which vary
greatly between individuals. This can be particularly important with elderly patients and also quite
challenging in infants.
In another product implementation, manual wave-
length tuning and bandwidth adjustment are per-
formed using two small knobs. This lowers the
package cost and size for applications requiring a
settable wavelength rather than a smoothly scanned
or stepped wavelength. And, in a third and even
smaller format, there are no adjustments, and the angles are all
factory-set and fixed. This enables immediate shipment of custom-select bandpass performance.
