The WFS-K2 kit combines the base camera unit and two interchangeable AR coated microlens arrays. The first array is 400 – 900 nm with a pitch of 150 µm. The second array is 400 – 900 nm with a pitch of 300 µm. The microlens arrays are mounted with a precision patent-pending magnetic holder. They can be easily interchanged using the pickup tool that is included with the kit, as shown in the photo to the right.
