COL_1 Collimator

  • Col_1 Monochromator or Light Source Collimator

Using a two-lens systems with three interchangeable apertures the COL_1 allows the user to optimise the throughput/power trade-off. An adjustable iris allows the user to set a beam diameter between 2 and 20mm.

Options include a range of lenses dependant on spectral range of use, and the COL_2 for us with the IL1 halogen light source.
