Lumetta compact spectrograph

High Sensitivity Imaging Spectrograph

Compact, affordable imaging spectrograph with deep-cooled scientific CCD

HORIBA Scientific’s new Lumetta™ delivers benchtop performance in a small, value priced package to the rapid compact spectrometer market. It offers the highest throughput/signal gathering capacity in its class, employing a tall sensor and an F/2 design. With a scientific grade-one high quantum efficiency CCD cooled to -50 ^oC, it provides a sensitivity that rivals more expensive high-end benchtop systems. As an imaging spectrograph, it enables advanced techniques such as multitrack spectroscopy and hyperspectral imaging ― all at an affordable price.

The Lumetta features:

• 1200:1 Signal-to-Noise
• 16-bit electronics with exceptionally low noise
• Lowest stray light in its class at <0.1%
• Highest optical throughput in its class:
  • 6.7 mm usable slit height
  • F/2 spectrograph matched with common fibers of 0.22NA
  • 40% longer focal length allowing wider slits (high throughput) for a given resolution
  • Large area sensors enable optical light gathering for low light application
  • Smallest CCD non-linearity for computational accuracy (<0.4%)
  • Top of the range on speed – up to 278 spectra/second
  • Accepts/couples to SMA FC and Ferrule Fiber termination
  • Can integrate for hours under low light conditions to build up the signal
