The Gentec-EO monitors come in various sizes and types to cover all applications. We have monitors with or without display (PC-based) and for power or energy readings, or both. We also offer the fastest digital needle display on the market.

  • Languages: Select the display language: English, German, Japanese or French (Firmware V1.04.02 or higher)



Use the elements in this menu to set everything related to your measurements:

  • Wavelength: Select one of the standard wavelengths offered, enter a custom value and create your own list of standard wavelengths.
  • Range: Set the measuring range to autoscale or a fixed scale.
  • Measure Mode: Use this menu to decide what type of measurements will be displayed: average power, single shot energy, pulse-to-pulse energy, etc.
  • Corrections: Enter multipliers and offsets.
  • Trigger Level: Set the trigger level in 0.1% steps, from 0.1% and 99.9%.


DUAL SCREEN DISPLAY (shown with Scope Display)

With the Dual Screen mode, the MAESTRO really takes full advantage of its extra-large screen! Any display mode can be used in both single or dual display mode. In dual display mode, the Real Time display takes the upper portion of the screen, while any of the other displays (Scope, Needle, Averaging or Statistics) is set on the lower portion. The display in the lower portion can be easily changed using the parameters bar with drop-down menus in the center of the screen. You can also expand one of the displays to have it in Full Screen mode using the maximize button. Just as easily, you can go back to Dual Screen display by using the minimize button.


This display shows the measured value in real time, with a corresponding bar graph below. The large size of the digits and high contrast of the graphics allow to see the measurement from a good distance. This mode is also always present in dual screen mode, in the upper portion of the screen.

  • Very Large Digits
  • Bar graph



With its line filling from the right of the screen, in a first-in/first-out manner, this display mode is a good approximation of an actual oscilloscope reading. Settings include time (x-axis) and range (y-axis). Basic statistics can also be displayed directly on the screen.

  • Oscilloscope-type graph
  • On-screen, real time statistics (min, max and average)
  • Fully customizable x and y axis



Exactly like an analog needle, only faster! This mode is particularly useful when tuning a laser. The Real Time value is also displayed at the top of the screen.

  • Ultra-fast readings
  • Great for tuning
  • Real Time value at the top of the screen
  • Min and Max Values hold



This very unique mode is perfect to show the trend of a laser over time. Set the number of points per batch and let the MAESTRO identify the minimum and maximum values of every batch. A yellow curve then follows the average of each batch, displayed as bars on the screen. The wider the difference between the white and blue portions of a bar (corresponding to the min and max values), the more unstable your laser is.

  • Calculates the min, max and average values of batches of measurements
  • Perfect to check laser stability over time
