LDH Series
Brand: PicoQuant | Category: Nanotechnology
The LDH Series are picosecond pulsed laser diode heads covering a broad range of wavelengths. The beam optics use a numerical aperture of 0.55, with typical divergence of 0.11 mrad and 0.32 mrad along the two beam axes and typically linear polarisation. They are used for time-resolved techniques and LiDAR.

- LDH-I Series
The LDH-I Series are smart picosecond laser diode heads covering the UV-A to the near infrared. They provide high power at high repetition rates, with a numerical aperture of 0.55 and a spectral width of about 2 to 8 nm below 900 nm. They are used for time-resolved methods including FLIM and TRPL.
- PDA-23
The PDA-23 is a cooled 23-pixel single photon avalanche diode array detector. It provides low-noise, high-efficiency single photon detection across all 23 pixels for imaging and time-correlated single photon counting. Reported uses include fluorescence correlation spectroscopy with SPAD arrays.
- LDH-FA Series
The LDH-FA Series are fibre amplified picosecond laser diode heads delivering high pulse energy and stable output. Configurations cover UV, visible and infrared wavelengths, and optional fibre coupling is available for beam delivery. They are used for time-resolved techniques and for LiDAR.
