• When projecting a mask image on a specimen by using a YAG laser system mounted on a Mitutoyo microscope unit, the mask image will be scaled by the factor f/200 times (f=200 mm, Mitutoyo tube lens).
Since the focal length (f) in ultraviolet radiation (λ = 266 nm) is slightly smaller than that in visible radiation (λ = 550 nm) as above, the working area in ultraviolet radiation also becomes slightly smaller than the mask image in visible radiation.
• Every resolution and single objective's depth of focus in the above table is a value determined on the basis of a reference wavelength (λ= 0.55 μm).
