Horizontal Light Path Profile Projectors essentially have the light travelling horizontally (Laterally or sideways) starting from from the source to hit the job on the work-stage and then through the objective to the screen. This is ideal for measuring a wide range of cylindrical profiles which are excessive long and further other jobs can be measured using fixtures. A few examples for suitable jobs are pump shafts, automotive engine shafts, hollow/solid cylindrical bearing shafts etc.
