    Optimet (Optical Metrology) product line was founded in 1995 by Ophir Optronics Solutions.  Ophir Optronics, now a part of MKS Instruments, is a global leader in precision IR optics, laser measurement instrumentation and 3D non-contact measurement equipment. Optimet develops and  manufactures non-contact distance measurement sensors based on the patented Conoscopic Holography technology.


    Optimet’s sensors are based on the unique and patented Conoscopic Holography technology,  which is advantageous over standard distance measurement methods used for various industrial applications. The sensors are reliable, accurate and contain no moving parts. Our technology  has major benefits when integrated in measurement systems compared to the standard  triangulation method. Two major advantages are:

    • Colinearity: our sensor's outgoing laser beam share the same optical axis as the reflected signal. This colinearity allows the sensor to measure inside holes, through folding optics, and steeply inclined surfaces of up to ±85°. The ability to incorporate relay optics enables the sensor to be used simultaneously with the same focusing lens of laser welding or cutting applications and with machine vision applications.

    • Low electronic noise dependency: In Optimet’s sensors the entire detector is used to evaluate a single spatial frequency, making the measurement highly noise resilient. Moreover, if some of the light  isblocked, other areas can provide sufficient measurement signal.

    Here are some of the unique properties of our sensors:


    There is a growing need for improved measurement solutions which offer higher precision,  speed and accuracy that will provide better in-process inspection measurements, resulting in lower manufacturing costs and improved products. Optimet's innovative sensors overcome the limitations of many existing measurement devices, in many cases providing the only comprehensive solution for  complex measurement problems. Optimet has a great variety of sensor configurations which address  a large number of demands of metrological measurements associated with many kinds of material  surfaces. For choosing the right sensor configuration the user must identify what kind of material  is involved, along with its surface properties. More specifically, is the material diffusive or reflective?  Transparent or translucent? Each material has its own physical and optical properties that must be  taken into consideration. Other factors which need to be taken into account are the standoff from  the object, the measurement range of the sensor and of course the precision needed for the specific application.


    A major advantage of Optimet's sensors is the separation between the sensor and the lens. Each  sensor head can be used with a large variety of lenses. This advantage allows a single sensor to cover a  large measuring range, standoff (distance from sensor to the center of measurement range) and  accuracy. Furthermore, Optimet's technology has real time control and filtering of SNR (Signal to Noise  Ratio) and Total (relative laser power collected) of the signal retrieved. These unique technological  properties along with the collinear optical configuration allow the perfect setup to match most known  applications.
