The DCRIV Halogen Light Source from SCHOTT provides the Ultimate Flexibility in Light Control.

Combining three products in the same footprint, the DCR® IV integrates a 150W halogen light source, a RS232 control interface, and an equalizer light feedback. The DCR® IV also incorporates user-friendly front equalizer controls and a simplified command protocol.

The DCR® IV equalizer light feedback provides stabilized light output for the most demanding machine vision inspection applications. The light feedback feature provides stable lamp output over the life of the lamp and minimized lamp-to-lamp variation. The DCR® IV can be operated using either a reference Modulamp® and off-the-shelf fiber optics, or with a reference bundle. Light feedback stability for these configurations is as follows:

Light Output with Reference Modulamp® Unit ±2%
Light Output with Independent Fibreoptic/Reference-Bundle ±1%
Lamp to Lamp Variation with reference Modulamp® Unit ±8%
Lamp to Lamp Variation with Fiberoptic/Reference-Bundle ±1%

The DCR® IV's built in RS232 interface allows the lamp to be controlled remotely, as well as indicates the status of the bulb. The DCR® IV also offers enhanced expansion capabilities by allowing the control of up to 3 DCR® III light sources from the DCR® IV's RS232 interface. Other capabilities include: restoring settings for all 4 independent light sources upon power up and the ability to embed checksum error codes in RS232 command strings.

The DCR® IV has all the popular DCR® III performance features including: a current limiting DC regulated power source, interchangeable Modulamp® units, soft start "lamp saver" circuitry, solid state dimmer control for continuous dimming, and a stackable design.
