MACRO ZOOM LENS FROM 0.8X TO 4X
(48X-240X with CCD 1/3" / field of view 6.2x4.6 - 2.4x1.8 mm)


   Macro zoom objective has been studied to be applied to 1/2" and 1/3" CCD, with the possibility of variable focal at continuous scale for magnification between 0.8X (= scale 1:1.25) and 4X (= 4:1), with a working distance of about 98 mm ± 4 mm.
   To enlarge the range of magnifications, four converters are available: 0.7, 0.5, 0.4 and 0.3. These converters allow to have: 0.56X ... 2.8X, 0.4X ... 2X, 0.32X ... 1.2X, 0.24X ... 1.2X.
   This lens can be mounted on a practical stand; the illumination can be of two types: ring and axial illumination with cold light, with optic fiber.
   To inspect narrow cavity, it is advisable to use axial illumination or incident light with reflecting substage mirror for the projection, parallel to the axis, of the light; this eliminate completely eventual shadows and allows a perfect inspection.
