HDX-Trigger Adapter for Ocean Insight (former Ocean-Optics) Spectrometers

Important announcement:
Unfortunately the 40-pin connector is no longer available. The manufacturer of that connector discontinued it, so we have stopped manufacturing the HDX trigger adapter. If you recently purchased one of these via Paypal, please request your refund as soon as possible or write to us at This email address is being protected from spambots.

The trigger adapter "HDX-TRIGGER" is a simple plug adapter. It has a BNC trigger input and a BNC output to sense the strobe signal, which indicates when the spectrometer enters integration. On the other hand it uses the 40-pin DD4 connector facing the spectrometer. The trigger input and the strobe output have overvoltage protection.

Internally the module converts the levels of the TTL input trigger to 3.3V levels and vice versa, so it is compatible with any of the mentioned spectrometers. 

The HDX-TRIGGER is useful in applications that require synchronizing the capture of an optical event, as in Laser Induced Breakdown Spectroscopy (LIBS).

Additionally it has a push button switch to generate a manual trigger. This is useful to easily test that the spectrometer and its software on the computer are active and capturing spectra.

HDX-TRIGGER is compatible with the following spectrometer models:

Ocean HDX, Ocean FX, Flame-S, Flame-T, Flame-NIR.
