Product Family Description

  • Stable Output
  • True On/Off Pulsed Control
  • Linear Amplitude or Time Modulation
  • Low Power Consumption
  • EMC/ESD Shielded
  • Focusable

This new design uses advanced circuits and components to eliminate unwanted variations in output. A single input allows the light intensity to be set using a simple resistor or voltage source. The output can be modulated rapidly with any arbitrary waveform. The module contains an industrial quality laser diode with built-in monitoring photodiode. An efficient processor controlled driver circuit is fully protected and matched to the diode. The stable adjustable focus lens mounting and case is electrically isolated from the electronics. A 4-way connector provides supply, control, and shielding inputs. Meet IEC60825 certification, in accordance with CDRH. Applications include: vision systems, telemetry, sensors, laboratory testing, and dynamic lighting.

A power supply, sold separately, is required for operation. We recommend #59-099 5V Universal Power Supply.
