The WFS-K1 kit combines the base camera unit and two interchangeable microlens arrays; one chrome mask and one AR coated microlens array. The chrome mask microlens array is 300 – 1100 nm with a pitch of 150 µm. The AR coated microlens 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.
