Scalar's DG-3 portable digital microscope has a 3.5 inch LCD for easy viewing, measurement bars can be calibrated for each lens and embedded in the image, and the preview mode insures that only best images are saved. The DG-3 has optional lenses from 25x to 1000x. The premier lens would be the 25x to 200x Parfocal Zoom Lens which makes it easy to magnify the exact item you would like to view in a broad range of magnifications.
Surfaces are magnified with its LED illuminated lenses (from 25x to 1000x) and then imaged by its 2.3 million-pixel CCD sensor. An engineer with Boeing at Kennedy Space Center reported that they are now using the Scalar DG-2A in close handheld inspections of bolt holes, bonding screens, corrosion, and braided flex hoses. The 25x-200x Parfocal Zoom lens can be used as a touch and view lens or it can provide about 1/2 inch working distance when its Touch Collar is removed. This zoom lens allows one to scan an area at 25x, bullseye a defect or area of interest, and then zoom to 200x without moving the lens. The surface of the material is preserved, time is conserved, and certainty is provided that the whole object has been inspected.
The strength of the DG-3 is its extreme portability. It can be used in the field or factory, in a fuselage, on animals, pipes, PCBs, and nearly any material requiring quality control or non-destructive testing. The cost of the unit begins at $5780 with optional lenses beginning at $660.
