Specifications — NIRONE Sensor

Spectral Engines high performance NIRONE Sensor for near-infrared wavelengths is a compact and robust tool for your NIR spectroscopic applications. These sensors are PCB mountable with a single connector for power and communication and two screws to fasten the sensor on the application board. Two integrated light sources allow easy implementation of different optical configurations. NIRONE Sensor provides an additional trigger signal that can be used to control a separate light source on your application board.

The parts are:

  1. Sensor optics

  2. Sensor

1 With an SMA-adapter and a fiber with 400 um core and 0.22 NA.
2 Specified by lamp manufacturer for ideal laboratory conditions. Lifetime may shorten as a result of shock, vibration, and extreme temperatures. Lifetime can be extended by using a lower than 100 % drive level.
3 With external illumination and signal level of 75% of the maximum range.
