Position two collimators for absorbance/transmission measurements of one sample
Position two collimators at 90?for fluorescence measurements
Position two pairs of collimators for simultaneous absorbance/transmission and fluorescence measurements of the same sample. You can even unscrew the collimating lenses from the holder assembly and use them separately, in any fixture for applications requiring a fiber for free-beam coupling

* There is no single combination of optical fibers that satisfies the requirements of every application. As a rule, however, it is best to use a large-diameter (>50 µm) illumination fiber to get maximum light throughput and a small-diameter (<50 µm) read fiber to achieve the best optical resolution
