What are the varieties of laser scan micrometer available? Above and beyond the basic concept of the laser scan micrometer, these tools come in different varieties and with different accessories that help to specify their measurement capabilities. They can be purchased in different sizes and models. Additionally, you might need a laser scan micrometer with a separate display unit or an integrated display, both of which are available. The four main types of laser scan micrometer include the automatic (sometimes called the inline), the bench-top (sometimes called the floor), the handheld (sometimes called the portable), and the machine-mounted. The typical optional accessories that are available alongside laser scan micrometers include: a workstage or an adjustable workstage, a calibration gage set, a wire guiding pulley, extension relay cables, extension signal cables, air-screen covers, and air-blow covers.
