The S12xC Standard Photodiode Power Sensors are ideal for metering low power coherent and incoherent sources from the UV to the NIR. These sensors feature an integrated viewing target for easy alignment, enhanced shielding against electromagnetic interference, over temperature alert device, and large Ø9.5 mm sensor aperture. The sensors are compatible with Ø1/2" posts and SM1 (1.035"-40) lens tubes and are ideal for free-space and fiber-coupled sources. They may also be mounted in 30 mm cage systems using our selection of 30 mm Cage System Optic Mounts with internal SM1 threading.
Each sensor is shipped with NIST- or PTB-traceable calibration data. The included data will match the calibration certification of the photodiode used to test the individual sensor. Thorlabs offers a recalibration service for these photodiode power sensors, which can be ordered below (see Item # CAL-UVPD for UV-extended Si sensors, Item # CAL-PD for Si sensors and Item # CAL-IRPD for Ge sensors).

The S170C Microscope Slide Power Sensor Head is a silicon photodiode sensor designed to measure the power at the sample in microscopy setups. The silicon photodiode can detect wavelengths between 350 nm and 1100 nm at optical powers between 10 nW and 150 mW. The sensor head's 76.0 mm x 25.2 mm footprint matches that of a standard microscope slide and is compatible with most standard upright and inverted microscopes.
The photodiode has an 18 mm x 18 mm active area and is contained in a sealed housing behind a neutral density (ND) filter with OD 1.5. A 20 mm x 20 mm indentation around the surface of the ND filter is sized to accept standard microscope cover slips. An immersion medium (water, glycerol, oil) may be placed in this well directly over the ND filter, or a cover slip may be inserted first to simplify clean up. The gap between the photodiode and the neutral density filter has been filled with an index matching gel in order to prevent internal reflections from causing significant measurement errors when using high NA objectives with oil or water.
The bottom of the sensor housing features a laser-engraved grid to aid in aligning and focusing the beam. In standard microscopes, this grid can be used for beam alignment before flipping the sensor head to face the objective for power measurements. In inverted microscopes, turn on the transmitted illuminator to align the grid on the detector housing with the beam, thereby centering the sensor in front of the objective. Alternatively, the diffusive surface of the ND filter can be used as a focusing plane.
Each sensor is shipped with NIST- or PTB-traceable calibration data. The included data will match the calibration certification of the photodiode used to test the individual sensor. Sensor specifications and the included NIST- or PTB-traceable calibration data are stored in non-volatile memory in the sensor connector and can be read out by the latest generation of Thorlabs power meters. We recommend yearly recalibration to ensure accuracy and performance. Calibration may be ordered using the CAL-PD recalibration service available below. Please contact technical support for more information.
The complete set of specifications are presented on the Specs tab above. Thorlabs also offers a Microscope Slide Sensor Head with a thermal sensor; the full presentation can be found here.
These Integrating Sphere Photodiode Power Sensors are the ideal choice for power measurements independent of beam uniformity, divergence angle, beam shape, or entrance angle, making them excellent for use with fiber sources and off-axis free space sources.
Our integrating spheres are designed for wavelength ranges from the visible through the NIR. Sensor heads for use between 350 and 2500 nm use a single Ø1" or Ø2" sphere made from Zenith® PTFE and feature a black housing to minimize reflected light around the entrance aperture. These sensors use either a silicon photodiode for detection in the 350 - 1100 nm range or an InGaAs photodiode for detection in the 800 - 1700 nm, 900 - 1650 nm, or 1200 - 2500 nm wavelength range.
The S180C integrating sphere for 2.9 - 5.5 µm uses two connected, gold-plated Ø20 mm spheres, with an entrance port in the first sphere and a port for the MCT (HgCdTe) detector located in the second sphere. Compared to single-sphere designs, the two-sphere configuration improves device sensitivity by minimizing the internal sphere surface area while still effectively shielding the detector from direct illumination. This design reduces the effect of input angle, divergence, and beam shape on the measurement result by effectively shielding the photodiode without the use of a baffle or other shielding mechanism.
The integrating spheres below feature large Ø5 mm, Ø7 mm, or Ø12 mm apertures, externally SM1-threaded (1.035"-40) front connections, enhanced shielding against electromagnetic interference, and an over-temperature alert sensor. Because of the large active detector areas of these sensors, the included S120-FC fiber adapter can be used with FC/PC- or FC/APC-terminated fiber. The externally SM1-threaded adapter can be removed using a size 1 screwdriver to place components closer to the window.
Each sensor is shipped with NIST- or PTB-traceable calibration data. The included data will match the calibration certification of the photodiode used to test the individual sensor. NIST- or PTB-traceable data is stored in the sensor connector. Thorlabs offers a recalibration service for these photodiode power sensors, which can be ordered below (see Item # CAL-PD for Si sensors, Item # CAL-IRPD for InGaAs sensors, and Item # CAL-MIRPD for extended InGaAs or MCT sensors).

These internally SM05-threaded (0.535"-40) adapters mate terminated fiber to our free-space detectors and power sensors, including, but not limited to:
For details on narrow versus wide key connectors, please see our Intro to Fiber tutorial. Please contact Tech Support if you are unsure if the adapter is mechanically compatible.
These internally SM1-threaded (1.035"-40) adapters mate terminated fiber to any of our externally SM1-threaded components, including a selection of our photodiode power sensors, our thermal power sensors, and our photodetectors.
The APC adapters have two dimples in the front surface that allow them to be tightened with the SPW909 or SPW801 spanner wrench. The dimples do not go all the way through the disk so that the adapter can be used in light-tight applications when paired with SM1 lens tubes.
For details on narrow versus wide key connectors, please see our Intro to Fiber tutorial. Please contact Tech Support if you are unsure if the adapter is mechanically compatible.
The SM1A29 adapter can be attached to our slim photodiode sensors using two setscrews, which are compatible with 0.035" (0.9 mm) hex keys. This allows for mounting SM1-threaded fiber adapters, filters, or other SM1-threaded mechanics or optics to our slim photodiode sensors. The target around the aperture uses the same material as our VRC2 Laser Viewing Card and is sensitive to light between the wavelength ranges of 400 - 645 nm and 800 - 1700 nm.
The FBSM FiberBench Mount enables stable mounting of our slim photodiode sensors into our FiberBench systems. A side-located setscrew with a 0.050" (1.3 mm) hex can be used to lock the sensor in place. The mount has dowel pins for compatibility with FiberBenches and an optical axis height of 0.56" (14.2 mm) to match other FiberBench components. The target around the aperture uses the same material as our VRC2 Laser Viewing Card and is sensitive to light between the wavelength ranges of 400 - 645 nm and 800 - 1700 nm.
The SM05A29 adapter can be attached to our compact slim photodiode sensors using two setscrews, which are compatible with 0.05" (1.3 mm) hex keys. This allows for mounting SM05-threaded fiber adapters, filters, or other SM05-threaded mechanics or optics to our compact slim photodiode sensors.
