The 34-514 from Edmund Optics is a portable Laser Power Meter that operates from 320 to 1100 nm. The device has LCD displays with touchscreen controls, the ability to adjust wavelength, brightness and screen orientation, and min/max display. This portable power meter can transfer data to a computer for data logging via a mini USB port. The silicon laser power meter has a folding body design with a click stop at 90 degrees, providing the unique ability of being placed on an optical table unmounted when oriented at 90 degrees. If the beam height is 78 mm off the optical table, you can simply set the folded power meter directly onto the table. It measures 212 x 41 x 15 mm, weighs 150 g and has 8 to 32 mounting holes for table top mounting. The meter comes with a rechargeable battery.
