Infrared (IR) Arrays For NIR Spectroscopy

LASER COMPONENTS offers a series of powerful IR arrays designed specifically for IR spectroscopy, photometry, industrial process control, and biomedical analysis applications. The IG22 array series consists of 256 rectangular pixels made of extended InGaAs with a TE2 cooler, and is manufactured with an element size of 30 µm x 250 µm, and a pitch of 50 µm.

Designed for spectroscopy up to 2.1 µm, these linear arrays feature a “dark pattern” due to the auto zero of the input offset, resulting a particularly large dynamic range. Additional features include eight different amplification levels, individual adjustment levels of each pixel for optimal signal-to-noise ratios, an integrated anti-alias filter, and an optimized thermal design.

IG22 Array specifications include:

  • 20% cut-off wavelength ≥ 2.10μm (@ 40°C)
  • Auto zeroing of input offset (<100 μV) results in reduced dark pattern
  • Correlated double sampling
  • 50 μm pitch
