Description Tables Metrology

They are used to focus light to a thin line for effective harmonic generation in nonlinear crystals, in laser scanners, spectroscopy, dye lasers, acousto-optics or other applications. They are the best for circularization of diode laser outputs, energy collection for linear detectors or for coupling to a slit input.
