An apparatus for enhanced viewing of objects in two separate simultaneous frequency bands of light that is constructed in accordance with the principles of the present invention includes a primary mirror and a moveable secondary mirror that is disposed above the primary mirror to provide a long focal length. A beam splitter splits the optical path into two paths, one for infrared and another path for visible. Various optical elements and devices are described along each path. The secondary mirror is displaced away from its concentric position over the primary mirror to provide shorter focal lengths in IR and visible. Focal Plane Arrays (FPA's) are disposed where desired along both optical paths for real-time viewing and data acquisition. The preferred FPA in visible is a CCD. The preferred FPA in IR is disposed in a Dewar.

The present invention relates to a method and apparatus for testing electrical traces wherein ultraviolet wavelengths from a laser source and visible wavelengths from a scanning camera are focused to a common focal plane. In a first embodiment of the method and apparatus, the wavelengths are commonly focused using an auxiliary lens having a power sufficient to accommodate the difference between the focusing plane of the ultraviolet laser source and the scanning camera. In a second embodiment, the wavelengths are commonly focused by moving the camera optics of the scanning camera relative to its visible light source. Both of these methods and apparatuses employ a fused silica lens system, avoiding the use of calcium fluoride.
