Light Sources

Halogen Light Source

The Ocean Insight HL-2000-LL light source comes standard with most of our flow injection analyzers

HL-2000-LL

Ocean Insight offers sturdy, reliable tungsten halogen light sources to meet your application requirements. The HL-2000-LL uses a unique long-lifetime lamp that extends operation to 10,000 hours. Our HL-2000 product family provides flexibility for your lab for measurements from 360-2400 nm.

All HL-2000 models have an integrated fan to keep source cool and stable, and a built-in holder that accommodates filters for conditioning the light. A universal power supply makes setup quick and easy.

Also available are the high-power (HP) and shutter option (FHSA) versions. The HL-2000-HP uses a 20-watt bulb for large-diameter optical fibers or fiber-probe bundles. Its intensity can be attenuated via an RS-232 module. The HL-2000-FHSA features a TTL shutter for attenuation.

Deuterium Light Source

DH-2000

The DH-2000 light source offers stable, continuous output from 215-2500 nm. Using a combination of deuterium and halogen lamps, the DH-2000 is ideal for measuring a sample that has multiple features in different spectral regions or for analyzing a variety of different samples in your lab. All models of the DH-2000 family include easy-to-replace bulbs, keeping your measurements going with fast lamp changes.

For those that need light into the deep UV, the DH-2000-FHS-DUV-TTL and DH-2000-S-DUV-TTL models include a special deep-UV deuterium lamp providing output from 190-2500 nm. Both models come with a shutter to limit the exposure of samples to the UV light.

The DH-2000-FHS-DUV-TTL comes with a filter holder for filters up to 25 mm square or 25 mm round in diameter and 4 mm in thickness, plus a shutter controlled via TTL signal or switch up to 5 Hz.

The DH-2000 light source uses a combination of deuterium and halogen lamps.
