Condensing lens for ultraviolet light
We offer a long focus condensing lens for ultraviolet light consisting of a set of 4 lenses.
feature
We offer lenses that can focus ultraviolet light with a long focal point. Light can be efficiently focused from outside the ultra-high vacuum chamber for micro focusing angular dispersive photoelectron spectroscopy (μ-ARPES).
In addition to standard products for wavelengths of 190 nm - 210 nm (photon energy 6 eV - 6.5 eV), we also offer custom products according to customer requests.
