When used with model 84499 or 84499-5, this optional f/1.4, 25 mm lens provides approximately a 31degree field of view and a magnification of 0.22 at its close focus distance of 114.3 mm, (4.5”).

The built-in manual iris can be used to control intensity and increase the depth-of-field. This helps to reduce the necessity to refocus for changes in distance.
