Stanford SR540 Optical Chopper

The SR540 from Stanford Research Systems will handle all your optical chopping requirements - from simple measurements to dual-beam and intermodulation experiments. The SR540 has a 4-digit frequency display, front-panel frequency control, analog voltage frequency control and two reference outputs with selectable operating modes. Two anodised aluminium blades are provided; a 5/6 slot blade for frequencies up to 400Hz and a 25/30 slot blade for frequencies up to 3.7kHz. Reference outputs are provided for frequencies corresponding to each row of slots, as well as the sum and difference frequencies.

Features:

• 4Hz to 3.7kHz chopping frequencies
• Low phase jitter
• Single and dual beam experiments
• Sum & difference reference outputs
• Bolt clamp or rod mounting
