Dual range laser diode driver for low power applications

4200-DR Series LaserSource

Arroyo Instruments Logo

The 4200-DR Series LaserSource dual range laser diode driver is ideal for low power applications, such as butterfly and TO-can lasers, as well as many LED applications. The compact enclosure takes up little space and offers an excellent value.

Many of our customers have switched to the 4300 after years of using other products, and they have all made the same discovery: Why spend significantly more when you can get the same performance for a fraction of the price?

The LaserSource has all the features you would expect from a laser driver, such as safety interlock, ESD protection, and hardware limit circuits for current and voltage. Dual range allows this instrument to operate at half-scale for improved resolution.

In addition, the LaserSource has unique features not found on competing products including optically isolated modulation and photodiode inputs, programmable PD bias, and a constant voltage control mode.

  • 100 mA, 500 mA, and 2,000 mA models available
