10-band Multispectral Solution

SWIR MultiSpec solutions that can address
your inspection issues

By combining CMICRO's dual-band SWIR line scan camera, NDB100H, with
ProPhotonix’s COBRA MultiSpec SWIR lighting system, it becomes possible
to introduce SWIR inspection systems with the following advantages over
a hyperspectral SWIR imaging system:

♦ Multispectral inspection of up to eight bands
     (10 wavelengths are selectable)
♦ Fast scan rate (10–40 kHz)
♦ Long lifespan (LED illumination)
♦ Cost-effective

10-band Multispectral Analysis

♦ Configurable LED lights with 10 wavelength bands are emitted from
     a COBRA MultiSpec SWIR.
♦ Reflected (or transmitted) light from the test objects is captured by
     two sensors of NDB100H
♦ Up to four bands from five wavelengths are captured by each sensor
     when the split wavelength is 1,250nm.
♦ The wavelengths of LEDs are sequentially switched for the same line.
♦ The reflected (or transmitted) light information of up to four bands
     for one scan line can be sequentially captured by each sensor.
♦ The maximum scan rate can be 10kHz, one-fourth of 40kHz,
     the maximum scan rate of NDB100H when four wavelengths
     information is captured for one scan line.
♦  In total, the SWIR line information of two wavelengths at 40kHz to
      eight wavelengths at 10kH becomes available.

ProPhotonix’s COBRA MultiSpec SWIR

The COBRA MultiSpec SWIR, with up to 12 wavelengths from 980nm to 1650nm, provides an ideal lighting solution when coupled with a multi-sensor SWIR camera. The wavelength choice for the COBRA MultiSpec is fully configurability and specific to the application in question. In addition, the high-speed strobe capabilities, and capacity for up to 4 independently triggered strobe groups, allow for sequential image acquisition across multiple sensors for even more detail material analysis.

The COBRA platform utilizes adjustable optics, specifically suited to the SWIR spectrum, which guarantees high-power, and narrow linewidth for a multitude of different working distances. Utilizing chip-on-board technology, and incorporating a choice of diffusors options, the COBRA MultiSpec SWIR guarantees best-in-class spectral uniformity and the flexibility to be used across a wide variety of applications. With over two decades of experience developing machine vision lighting for specific applications, ProPhotonix is well-positioned to help you get the most from your SWIR imaging application.
