Congratulations to Rudolf Mayer and Steve McMahon
1. No More Costly Microscope Collisions:
Users have been known to ram the microscope objective into the test specimen while manually jogging the microscope downward in an attempt to bring the indent image into focus. This type of collision can destroy the objective, the turret and the XY stage.
The VH3100 uses a unique demountable kinematic connection of the objectives that senses any collision and responds by retreating the actuator before any components are damaged, saving the customer five-thousand dollars in repairs and days of downtime.
2. No More Rotating Turret:
All other Vickers testers use a multi-position rotatable turret to hold and select the microscope objectives and the indenters. These turret systems are rather complex (with motors & controllers and drive systems) and may be prone to needing service.
The VH3100 was designed with a unique two-objective microscope system that uses one camera, a few half-mirrors and two light sources to create a “virtual turret” that switches between objectives by simply switching which light is on. Our thinking was’ “fewer moving parts means fewer service calls”; indeed, this system has proven to be very reliable.
3. No More Compromising on indenter Angle Adjustment:
Previous Wilson Vickers testers required elaborate shimming of the XY stage to obtain symmetric indents from one of the indenters and we would hope that the second indenters would also be sufficiently aligned.
The VH3100 was designed with an easy-to-use, adjustable three degree-of-freedom mounting between each load cell and its indenter; ensuring alignment of BOTH indenters.
4. Repeatable X-Y Stage Mounting:
Previous Wilson Vickers testers had a threaded-post XY stage mounting that had poor repeatability in positioning. That is, if you moved it (for service or system install), all alignment would be lost and only re-obtained through a tedious hit-or-miss try-and-retry method.
The VH3100 was designed with a push-and-lock mounting plate that exactly-constrains the X and Y positions. This mounting also has an easily adjusted and lockable Z axis rotation mechanism that ensures, after removal and reinstallation, repeatability of all stage positions.
