ASD 1° Field-of-View Mirror Fore Optic
This photo shows the 1° FOV fore optic with rifle scope (Item no. 11950). Because this
fore optic's primary is a mirror, the fore optic's field of view is constant at all
wavelengths. This is most important when the measured surface is at a great distance from
the fore optic (e.g. when collecting spectra from an aircraft or helicopter). When used
with the FieldSpec VNIR, this fore optic provides about a 0.5° FOV.
