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.

• 36 W output power
• High stability 0.0005 °C/°C
• Thermistor, RTD and IC sensors
• Auto-tuning of loop parameters
• Dynamic switching between CT and CC modes

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.

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.

The PS300 Series High Voltage Power Supplies — rugged, compact, reliable instruments for just about any high voltage application.

With up to 20 kV output capability, a GPIB computer interface, and 0.001 % voltage regulation, these high voltage power supplies have become the industry standard.

There are several models to choose from, with outputs ranging from 1.25 kV to 20 kV.
