Quasar-UltraCool spectrometers offer high-performance spectroscopy measurements in a compact form factor. The newest member to our StellarElite line combines our high throughput Quasar optics for 10x optical gain and Low Dark Current (LDC) detector technology to provide lower background noise than is possible with traditional font/back-illuminated detectors. Quasar-UltraCool’s CCD detector is vacuum sealed and cooled to -60 °C with peak quantum efficiencies of up to 95%! The Quasar-UltraCool is available in a variety of wavelength configurations including specialty configurations for Raman spectroscopy and custom low-light applications.
Quasar-785-UltraCool includes high throughput 10x optical gain and a low dark current, vacuum sealed, and deep cooled CCD array detector.
Quasar-532-UltraCool includes high throughput 10x optical gain and a low dark current, vacuum sealed, and deep cooled CCD array detector.
