Lamp Types

Two different light sources provide the light for a wavelength detection range from 190 nm to 750 nm (VC-D40), or from 190 nm to 900 nm (VF-D40). Note that the VIS lamp is optional for VC-D40.

Refer to the table below to find out which lamp is recommended if at least one of your detection wavelengths is within the range indicated in the left column.

At least one detection wavelength

Recommended lamp(s)

≤ 345 nm

UV

Between 346 and 670 nm

UV and VIS (turn on both lamps)

> 670 nm

VIS

Identification Chip

Each lamp is equipped with an identification (ID) chip. The ID chip stores information about the lamp, including the number of lamp ignitions, and the operating time of the lamp, thus providing an overview of the lamp status.

When a lamp is installed, the ID chip is automatically connected to the detector electronics.
