Optical inspection instruments can be put into four basic categories. Optical comparators, microscopes, video and laser systems. Optical comparators utilize traditional optics to magnify and project the image of an object onto a glass screen. This type of optical inspection instrument is by far the most widely used and is also the least expensive method of optical non-contact inspection in use today.
The basic principle of an optical gaging instrument is to provide a method to inspect a desired feature with versatile way of non-contact gaging. This enables manufacturers the ability to inspect a wide variety of parts without the need for complex fixtures. This non-contact method of inspection allows an inspector to view a desired feature using the magnification ability of optics. Optical inspection instruments allow to determine characteristics such as size, shape, location or surface finish.
