Can Be Used On Tiny and Large Bore Diameters For Openings from .039" and Up.Depth of focus from .020" to 10.00".
The Micro-Bore Viewing System is a unique concept for checking micro-bores and cavities. It is composed of 17 different lenses each with a predetermined focal length. These lenses are mounted in a rotary disc and marked from .5 to 25 determining the focal length in millimeters when multiplied by a factor of 10. The disc is rotated clockwise to focus from the minimum to the maximum depth. Magnification is 10x at minimum focal point and decreases to 2x at the furthest point. The illumination system is on the Optical Axis and provided by a miniature 2.5 volt Halogen Light Bulb. It is adjustable with an exterior intensity switch. The light is then collimated and projected on a mirror that bends the light path 90° down the length of the tube or cavity. For deep cavities, additional illumination may be needed. This can be provided as back lighting by the FLEXBAR FLEXIBLE BEND-A-LIGHT.
