Arroyo Instruments

Arroyo Instruments is a supplier of laser diode and LED drivers, temperature controllers, and fixtures. We have solutions for the LED industry, including precision low and medium power drivers, mounting solutions for various LED packages, and a broad range of temperature control options. On the diode driver side, our LaserSource diode driver offers high stability and low noise performance, and current ranges from 100mA to 20A. Our standard supplies will work with all conventional LEDs, and we also offer high voltage configuration for LED arrays. For those looking for a microsecond pulse driver, the 4300 Series LaserSource supports 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 ranging from 24W to 120W of TEC output power. The lower cost 5235 is a 24W controller, and supports thermistor seconds. 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. All instruments feature a bright VFD display, and RS232 and USB computer interfaces. Specific for LEDs, we offer our 226 LaserMount, which is a temperature controlled fixture that has a mounting pattern for STAR LEDs, in addition to additional mounting options. For high power LEDs, we offer the 264, which can support as much as 35W of waste heat at 25C. We also offer a broad array of
