Characteristics

◎ Spectral distribution

Deuterium lamps emit high intensity light in the UV range at wavelengths shorter than 400 nm. Light intensity on the short wavelength side is deter- mined by the window material used

◎ Arc distribution

Arc distribution of deuterium lamps is determined by the aperture (light exit) size. At the same input current and voltage, lamps with a 0.5 mm aperture provide 1.4 times higher intensity than lamps with a 1.0 mm diameter aperture.

POWER SUPPLY

Applications using L2D2 lamps require a very stable light output, so using a Hamamatsu dedicated power supply is recommended to operate these lamps.

Our dedicated power supplies use a constant-current circuit and constant-voltage circuit that deliver stable and reliable lamp ignition. Two types of power supplies are available: AC input (100 V to 240 V) type C9598 and 24 V dc input type M9596. Please select the power supply that matches your application.

LAMP HOUSING

These lamp housings are designed for Hamamatsu L2D2 lamps with a mounting flange. Despite being low cost and compact, these lamp housings also function as efficient heat radiator housings to allow stable L2D2 lamp operation.

The window and mounting surface of these lamp housings are finish-machined and have tapped holes, making it easier to install them in equipment.

These lamp housings are ideal for designing photometric equipment that uses L2D2 lamps.
