JULIGHT VSM-1000-MICRO Series - Microscope laser vibrometers

Description

The VSM-1000-MICRO features a Laser Vibrometer optical head coupled to a digital microscope with a monochrome 1.6MP camera. The Mitutoyo-type long working-distance microscope objective tightly focused the laser beam, allowing to measure the vibration of very small objects, like MEMS, MOEMS, micromembranes, biological samples and insects.
The lightweight Julight optical head allows for a smart design that features a movable microscope column, that can be translated along X and Y using a manual or motorized micropositioner, instead of the usual configuration where the object under test is
mounted onto a translation stage. In this way, it is possible to easily test objects that are naturally attached/mounted onto larger structures, allowing for high flexibility of use and operation. The vertical focusing can be manual or motorized.
The tight focusing of the microscope objective (standard magnification: 10X, optional magnifications: 5X, 20X, 50X) also allows vibration measurements on highly reflective surfaces, even if inclined ad at angle (up to 60° and more is tolerated).

Technical data

• The VSM-1000-MICRO-A model only operates as microscope vibrometer.
• In the VSM-1000-MICRO-B model, the optical head can be detached and used as a standard vibrometer with fixed working distance (that can be selected by the customer at the time of order, the standard fixed working distance is 400mm) .
• In the VSM-1000-MICRO-PLUS model, the optical head can be detached and used as a standard vibrometer with full working distance from 0.1 m to 5 m.
