Motorized Pinhole Wheel, Uncoated Chapter 3: Description
Chapter 3 Description
The MPH16-UC is an optically encoded, high-precision motorized pinhole
wheel. It enables automated and repeatable positioning of pinholes for applic-
ations such as confocal laser scanning microscopy or scanning oph-
thalmoscopy. Additionally, the MPH16-UC has a chrome-plated glass disk that
is manufactured using standard photolithography techniques. This disk consists
of 16 pinholes ranging from Ø25
µ
m to Ø2 mm.
The MPH16-UC connects to a computer through a USB port. A DLL or GUI soft-
ware controls the pinhole wheel. An optically encoded motor provides repeat-
able selection between pinholes with a resolution of 10
µ
m, without the need for
realignment. Radial positioning of the pinhole is accomplished by adjusting the
focusing lens with a fine adjustment screw. The detection end has an SMA fiber
connector for efficient collection of the spatially filtered light. While our standard
MPH16-UC ships with an SMA fiber connector, other connectors are available
upon request; please contact
imagingsales@thorlabs.com for details.
Note: The position of each pinhole (0-15), reported by the DLL of GUI, directly
corresponds to the pinhole diameters (Ø25 µm - Ø2 mm), from smallest to
largest (refer to the SDK manual for details).
