Schott has released a new light source that provides stable lighting for the most demanding machine vision applications.
Schott has just released a new light source for the most demanding machine vision applications.
Combining three products in one, the DCR IV integrates a 150W halogen light source, an RS232 control interface, and an equaliser light feedback.
The DCR IV also incorporates user-friendly front equaliser controls and a simplified command protocol.
The DCR IV equaliser light feedback provides stabilised 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 minimised lamp-to-lamp variation.
The DCR IV can be operated using either a reference Modulamp and off-the-shelf fibre 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 fibre optic/reference-bundle +/-1%; lamp to lamp variation with reference Modulamp unit +/-8%; and lamp to lamp variation with fibre optic/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 three DCR III light sources from the DCR IV's RS232 interface.
Other capabilities include: restoring settings for all four independent light sources on 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.
