General Information

FOG production


In 1990 Fizoptika, one of the world's leading fiber optic gyroscope (FOG) manufacturers, invented:




Series in production:

VG910 since 1990

VG091 since 1995

VG103 since 2010


- 40 µm PM optical fiber for an FOG;

jointless technology for manufacturing

  an all-fiber sensing assembly;

in-line high performance crystal-fiber polarizer; 

soldering technique for robust SLD-module manufacturing.


By 1995 Fizoptika had set up high volume cost-effective manufacturing of high performance FOGs and since then has delivered more than 140000 sensors worldwide.

Fizoptika gyros are used all over the world as embedded devices by original equip- ment manufacturers (OEMs) or as stand-alone sensors for testing and measurement to provide critical monitoring, feedback and control input. Our innovative technologies enable the customers to enhance their overall system performance by significantly reducing the size and weight of their products as well as manufacturing cost.

  • VG091 series
    Ultra-compact gyros

    Size   Ø 24.4 x 51.6 mm
    Weight        30 gram

    VG091 series

    The basic model of this series is VG091A - the smallest and lightest ever fiber optic gyro. The series features thumb-sized design combined with instant start-up and low power consumption. There are fiber optic gyroscopes with north seeking capability, magnetic immunity and suppressed vibration response. The gyro sensor VG091B has orthogonal (compared to VG091A) sensing axis orientation.

  • VG910 series
    Extra reliable gyros

    Shock     1 200 g, 1 ms
        95 000 h

    VG910 series

    This fiber optic gyroscope series features robust and reliable design coupled with a choice of outputs (differential, single-ended, digital). The wide range of models includes extra durable gyros, unmatched bias performance gyroscopes and high temperature operating FOGs. The basic model of the series is the VG910H.

  • VG103 series
    Fully plastic gyros

    Weight   40 gram
    ARW      0.01 deg/√h

    more info

    VG103 series

    This fiber optic gyro series features compact fully plastic design (no metal parts) coupled with a choice of outputs (differential, single-ended, digital) at low cost. The basic model VG103PT offers the best combination of excellent performance and superb shock/vibration endurance. The gyroscope sensor VG103LN stands out for its extremely low noise. There are also highly precise over a wide temperature range FOGs and an ultra compact gyro VG103S with exceptional shock endurance in the series.

  • VG095 series
    Compact gyros

    Bias stability     2 deg/h
    SF stability

    VG095 series

    This fiber optic gyroscope series features compact and lightweight "box" design coupled with a choice of outputs (differential, single-ended, digital) and housing (aluminium, plastic). The basic model VG095M offers exceptional bias stability and immunity to vibrations. The fully plastic gyro VG071PT can operate at extremely low temperature.

  • VG035 series
    Customizable gyros

    ARW    0.003 deg/√h
       40 cl

    more info

    VG035 series

    This fiber optic gyro series features low weight for its size due to sensors' plastic housing. The basic model VG035 demonstrates excellent bias and scale factor stability. The gyroscope VG035 design provides a spare inner space for customizing. A modified sensing coil and additional electronics blocks may be embedded to tailor the gyro's characteristics on request.
