We are proud to annouce the launch of the LDC501 Laser Diode Controller, the SR470/474 Optical Shutter Systems, the PTC10 Programmable Temperature Controller and PS300 20kV power supply from Stanford Research Systems.
LDC501 Laser Diode Controller
The LDC501 Laser Diode Controller is a highly stable, low-noise current source, with an integrated temperature controller — all at a very affordable price.
The LDC501 is the ideal instrument for controlling the current and temperature of your laser diodes. It has the performance and features you expect from instruments costing twice as much.
With a low-noise current source that delivers up to 500 mA, a 36 W high-precision temperature controller, and standard computer interfaces including Ethernet, the LDC501 is the right choice for your laser diode testing and control.
| Laser Diode Controller | TEC Controller |
| 500 mA low-noise current source | 36 W output power |
| Low drift (<10 ppm/°C) | High stability 0.0005 °C/°C |
| High bandwidth modulation (1.1 MHz) | Thermistor, RTD and IC sensors |
| Dynamic switching between CC and CP modes | Auto-tuning of loop parameters |
| GPIB, RS-232 and Ethernet interfaces | Dynamic switching between CT and CC modes |

SR470/SR474 Optical Shutter System
SRS have introduced two new optical shutter systems — the SR470 Laser Shutter Controller and SR474 Four-Channel Laser Shutter Driver. These shutter systems are designed specifically to minimize vibration on your optical table.
They are built around a unique shutter head, supported by one of two available controller models. The SR470 provides timing signals to a single shutter head, while the multi-channel SR474 drives up to four shutter heads, and is controlled by external timing signals.
- Ultra-low vibration shutter head
- True mechanical laser beam blocking
- >10 M cycle lifetime
- Microprocessor controlled timing
- DC to 125 Hz (any duty cycle)
- Easy to align 3 mm aperture
- GPIB, RS-232, Ethernet interfaces

PTC10 Programmable Temperature Controller
Introducing the PTC10 Programmable Temperature Controller from SRS — the ideal instrument for measuring temperature, controlling heaters, and logging temperature data.
The PTC10 Programmable Temperature Controller is a modular system that can be configured to suit a wide range of applications. The system consists of the PTC10 Controller and up to four I/O cards — two types of input cards for RTDs and thermocouples, and two types of output cards for controlling heaters. The I/O cards are ordered separately, and you can mix and match them in any way you wish.
- Up to 16 input channels
- Up to 4 PID feedback control channels
- 50 Hz PID sampling
- 1 mK resolution
- Data logging on removeable flash media
- USB, Ethernet, RS232 interfaces (std.)
- GPIB interface (opt.)
