A simple Connectorized U-bracket allows setting the desired intensity attenuation or spectral filtering by inserting the appropriate mini filter from the set.

The inserts can be fitted with attenuating filters or spectral filters made from a variety of glass materials.

This micro splitter separates incoming beam into two output beams of equal intensity.

The Light Intensity Distributor is basically an intensity splitter.

Thorlabs' Ø1' mounted pellicle beamsplitters are ideal for use in applications where chromatic dispersion must be minimized (i.e. cases where focused beams are necessary).
