S140C In Stock

The ThorLabs S140C is an advanced integrating sphere power sensor head, engineered to provide accurate and reliable measurements of the optical power of incoming beams, regardless of divergence and beam shape. The S140C is ideally suited for power measurements that require independence from divergence or entrance angle, as well as beam uniformity and shape, making it the perfect tool for use with fiber and off-axis free space sources.

The S140C has an impressive power detection range, being able to recognize power levels anywhere from 1 µW to 500 mW. This wide range of intensities gives it great flexibility. Its detection mechanism is based on a high-performance silicon photodiode, which ensures reliable and precise measurements in the wavelength range of 350 nm to 1100 nm. The S140C is specially created to be easily linked with power meter display devices. It also features a non-volatile memory at the sensor connection point that includes all the necessary data for easy acquisition and assessment. The S140C is incredibly versatile, and its compatibility with a SM1 (1.035"-40) thread adapter and FC fiber adapter makes it an indispensable tool for fiber-coupled and free space applications. Furthermore, the S140C is designed with 8-32 tapped holes and M4 tapped holes, offering the possibility of attachment to 1/2" posts and post holders with flexibility.
