MPX-1 Encircled Flux meter

The MPX-1 Modal Explorer provides real-time measurement of Encircled Flux at 850nm. Simply connect your source and patchcord to the MPX, and it will measure their Modal Launch Conditions in real-time.

Standards compliant - have confidence in its accuracy

Encircled Flux is now widely accepted as the preferred way to specify modal filling by IEEE, TIA and IEC. Measurement of Encircled Flux is defined in FOTP-203 - the "Modal Explorer" is the most standards-compliant measurement system available today and has been chosen by major standards labs in the USA and Europe as the basis for their critical measurements.

Robust and reliable - ready for production

Its compact size and solid design make it the tool of choice in cable makers, fiber optic instrument companies and VCSEL, laser and LED source makers. In use in factories every day, major players in the industry rely on the Modal Explorer. This version of software also supports the MPX API – a new way to access data and control the MPX programmatically. This enables automated testing and incorporation of the MPX into automated test routines.

Release v8.0 of MPX software is applicable to users of both MPX1 ( 850nm ) and MPX2 (1300nm ) with a USB 2.0 interface between computer and MPX optical unit. We strongly recommend all applicable users to upgrade. This version of software also supports the MPX API – a new way to access data and control the MPX programmatically. This enables automated testing and incorporation of the MPX into automated test routines. Please contact support@ardenphotonics.com to get a quotation.

Please note – some early MPX-1s had an analog camera. ( serial number 1052 and lower ) and these units are not supported by the Version 8.0 software. If you have an analog MPX-1 and you want to take advantage of the latest software we can offer a hardware upgrade as well. Please contact us on the email address above to get a quotation.

Main features:

Feature Benefit
MPX API A new way to control and access data from the MPX programmatically to enable automated testing and enable incorporation of the MPX into integrated test routines (additional license required).
New Aerospace Templates New alternative template type to allow aerospace users to specify maximum and minimum radial widths for a set of given intensities.
Windows 10 32/64 bit processor support Can run on all the latest Windows computers. So there is no problem fitting in with your company’s IT departments requirements.
Larger Field of View Field of view increased by 16% to make fiber positioning and calibrating easier.
110µm maximum core diameter Increased maximum custom core diameter – can now create templates for fibers with cores of up 110µm.
