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:

ㆍ 1200:1 Signal-to-Noise
ㆍ 16-bit electronics with exceptionally low noise
ㆍ Lowest stray light in its class at <0.1%
ㆍ 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
