APPARATUS FOR MICROSCOPIC DETECTION OF HARDNESS |
摘要 |
An adjustable stage mount includes a housing having a base defining a hole and an adjustable stage including a ball joint extension that rotatably engages the hole and is rotatably securable about the x-, y-, and z-axes. An adjustable indenter mount includes a housing defining a hole and an adjustable indenter including a ball joint extension that rotatably engages the hole and is rotatably securable about the x-, y-, and z-axes. A collision protection switch includes a first plate having three pairs of electrically conductive spaced apart pins wired to a voltage source in an open circuit, and a second plate having three electrically conductive balls. A spring pulls the first and second plates together causing the three balls to complete the circuit. A sufficient force against the second plate causes a ball to disengage and open the circuit. A two-objective microscope includes two parallel objectives, upper and lower light sources, three half-mirrors, and a camera. The camera and the half-mirrors are configured such that the camera views through either objective depending on which light source is on. |
