DH-2000-S-DUV-TTL Ocean Optics Deuterium-Tungsten 190-2500nm


DH2000-DUV with shutter, ext. TTL control, 190-2500 nm


Ocean Optics deep UV deuterium tungsten source.

The Ocean Optics 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.

The DH-2000-S-DUV-TTL 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.
