- Spectrally Purified Output
- Compact plug-and-play design
Product Description
The VPL series of diode lasers provide variable width pulses in the ns to ms range, as well as CW operation with powers up to 60 mW.
They are optimised for long photoluminescence lifetime measurements using the Multi-Channel Scaling (MCS) detection method. The width of the excitation pulses is easily controlled from the VPL allowing quick optimisation of the measurement conditions.
The VPL lasers are compact, maintenance free, and user-friendly. Although they are designed to match Edinburgh Instruments spectrometers, they can be incorporated into any experiment thanks to their external trigger capability.
