PXT1 In Stock

The PXT1 by ThorLabs is a housing that serves as the perfect solution for creating light-tight connections between the Ø1-1/8" barrel side-on photomultiplier tubes (PMTs) and SM1 (1.035"-40) lens tubes and 30 mm cage system. The PXT1 eliminates the need to design a custom adapter plate for a PMT, resulting in quick and efficient connectivity in a variety of applications.

Designed with precision, the PXT1 features internal SM1 threads that are 0.38" (9.5 mm) deep, allowing easy connections to compatible Ø1" lens tubes. The four Ø6 mm holes accept cage rods and are strategically spaced for compatibility with a 30 mm cage system. For post mounting, the PXT1 body boasts two 8-32 tapped holes and one 1/4"-20 tapped hole, providing flexibility in your set-up. To insert a PMT into the PXT1 housing, simply remove the retention collar first. Then, slide the active area of the PMT into the body of the housing, where an O-ring creates a light-tight seal. Fasten the retention collar to lock the PMT in and create a second light-tight seal. Please note that the PXT1 housing is not compatible with PMTs that have windows which protrude outside the cylindrical Ø1-1/8" profile.
