4200-DR

The 4200 Series LaserSource is a high-accuracy, dual-range laser driver for low-power laser and LED applications. This laser driver offers features typically found in only more expensive units, such as overlapping laser protection systems, high modulation rates, and programmable PD bias.

4200 FEATURES:

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 starting at only $995, the 4200-DR 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.
