Company Description

Arroyo Instruments is a supplier of leading edge diode drivers, temperature controllers, and device fixtures. We offer both bench top and OEM power supplies in a wide range of power levels, and a wide range of heat sinks for lasers and LEDs.

Our diode driver offers high stability and low noise performance, and current ranges from 100mA to 20A. Our standard supplies will work with all conventional lasers and LEDs, and we also offer high voltage configuration for diode arrays. For those looking for a microsecond pulse driver, the 4300 Series LaserSource features an optional QCW (quasi-CW) mode, with pulse widths as narrow as 100 microseconds.

For temperature control, our TECSource temperature controllers feature 0.004°C stability and the models starting from 28W of TEC output power. The lower cost 5240 is a 28W controller, and supports thermistor inputs. The 5300 Series, with 60W and 120W models, adds support for IC sensors and RTD, as well as an auxiliary 12V DC power supply, which can be used to power fixture fans. Higher power controllers are available on a custom basis
please contact Arroyo for more information.

Our bench-top instruments feature a bright VFD display, while our Pak series offers a compact, display-less enclosure for embedded or low cost applications. All instruments include a USB computer interface, and many also include RS-232.
