Brand: ThorLabs | Category: Scientific & Laboratory Equipment

Photomultiplier modules with bialkali, multialkali or GaAsP photocathodes for detecting faint optical signals. Their large active areas suit divergent light, and SM1 or C-Mount threading lets filters and lens tubes attach directly.
| Parameter | Value |
|---|---|
| Wavelength coverage | 185 to 920 nm across the range |
| Specification | Typical radiant sensitivities from 51 mA/W to more than 189 mA/W |
| PMTSS gain | greater than 1.0 x 107 |
| Specification | Photocathode active areas up to 22 mm diameter |
| Specification | Dark current from 2 nA typical depending on model |
| Specification | SM1 (1.035"-40) or C-Mount threading, 30 mm cage taps, post and table mounting |

Detectors that report the position of an incident beam rather than just its power. The lateral effect PDP90A is insensitive to beam shape, while the segmented quadrant models suit automatic alignment and beam stabilisation loops.
Actively quenched, temperature stabilised silicon avalanche photodiode modules that produce a TTL pulse for every detected photon. They pair with correlated photon pair sources for quantum optics teaching, and also suit photon correlation spectroscopy and LIDAR.
Integrating spheres in black anodised aluminium that spread incoming light evenly by multiple internal reflections. They are used for laser power, flux, reflectance and radiance measurements, and take Thorlabs SM05PD photodiodes directly.
