Light Sources
Ocean Insight manufactures a number of light sources which cover broad UV-Vis-NIR range. They can be used for illumination as well as excitation and calibration purposes.
UV-Vis-NIR Light Sources: Deuterium & Tungsten, Xenon Light Sources
PX-2 Xenon Light Source
Deuterium-halogen as well as Xenon (apart from the pulsed-Xe model) light sources cover the widest spectral range and are generally used for absorbance, reflectance, colour and fluorescence measurements.
| Model | Illumination source | Spectral range, nm |
| DH-2000-BAL | Deuterium & Tungsten Halogen | 210-2500 |
| DH-2000-FHS-DUV-TTL | Deep-UV Deuterium & Tungsten Halogen | 190-2500 |
| PX-2 | Pulsed Xenon | 220-750 |
| HPX-2000 | Continuous Xenon | 185-2000 |
Vis-NIR Light Sources: Tungsten-Halogen & Krypton Light Sources
HL-2000 Tungsten-Halogen Light Source
There are several choices of the traditional Tungsten Halogen light sources providing spectral output between 360 and 2400 nm, while the Krypton light source can be used between 400 and 2500 nm.
The Krypton light source additionally displays an integrated cuvette holder (10 mm) which can be used for either absorbance or fluorescence measurements.
| Model | Illumination source | Spectral range, nm |
| HL-2000-LL | Long Lifetime Tungsten Halogen | 360-2400 |
| HL-2000-HP-FHSA | High-powered Tungsten Halogen | 360-2400 |
| ECOVIS | Krypton Halogen | 400-2500 |
Raman Lasers
