Thorlabs MCLS1 Multi-Channel Fiber Coupled Laser Source 635nm
635 nm on four channels, with analog modulation on the back
The analog modulation input is the specification that decides what experiments this can run. With 0 to 1.5 V driving the output, intensity becomes a signal you can generate externally: lock-in detection, ramps, pulse trains, anything a function generator can produce. Without it you get on and off.
Four independent channels at 635 nm, fibre-coupled, with a hardware interlock. This is the workhorse configuration for fluorescence excitation, alignment and general photonics where 635 nm is the line you need.
Where it earns its place
- Lock-in and modulated detection driven by an external analog signal
- Fluorescence excitation and alignment at 635 nm
- Feeding four separate fibre paths from one source
- Teaching and prototyping benches needing a safe interlocked source
