Photodiode Laser Power Measurement Systems

New CW, low power photodiode laser measurement systems are now available from Scientech. These hardy systems consist of a handheld meter and your choice of highly sensitive, silicon optical detectors. Utilizing intelligent detector technology, these easy-to –use handy systems provide wavelength compensation along with a slim profile.

The Astral Series AI51/AI51D indicators are a compact, portable, handheld device in a rugged, metal case. The AI51 marries both a 4-digit LCD display along with a true analog needle meter movement. The needle makes laser tuning a cinch with no possible misinterpretation of digits. Or you may choose the AI51D which is the digital only version of the AI51. Both meters make wavelength corrections at the push of a button. The meter can be powered by the standard wall mounted power supply/battery charger, the optional USB data interface, or the optional battery. Optional meter accessories include a lithium-poly battery, a non-skid weighted base mounting system, a soft case, a hard sided carrying case, and a USB data interface with drivers.

Although the Astral Series AP50S/AP50UVS detectors possess a large aperture of 11mm and a slim profile of 2.8cm, they are both able to resolve down to 10nW. The maximum power of the AP50S is 50mW and can be expanded to 1W if you purchase the optional APXVIS attenuator. The maximum power of the AP50UVS is 4mW and can be expanded to 400mW if you purchase the optional APXUV attenuator. Both attenuators slip fit into the 11mm aperture for ease of use.

Each detector also comes with a NIST traceable calibration certificate to insure that you are getting the most accurate laser measurement possible. Standard equipment for the detectors includes a 1.27cm diameter x 8.89 cm long mounting post for easy mounting to optical tables and an aperture extension for blocking out unwanted environmental light sources. This extension is easily removed allowing close proximity to the absorbing surface for measuring diverging beams. Removing the aperture extension also permits the detectors to fit into tight spaces. Optional accessories for the detectors include two different holding bases.

Optional Accessories

Mounting System

This sturdy mounting system has a moldable, weighted, rubber base with a non-slip surface, ball mounts, and an Astral Series S cradle. The system will hold the Astral Series S meter up to 12 inches vertically above your working surface in an upright position. The ball mounts let you reposition the meter to accommodate any viewing angle you desire. You can also readily remove the Astral Series S meter for safekeeping at the end of the day.

Bases

These bases will hold the Astral Series S Detector upright on your working surface. Base 11788, which is a slotted base, will bolt down to your optical bench. Base 301019 will work on any surface.

Lithium Battery

The battery can be easily installed either in the field or at the factory. It is a rechargeable, lithium-poly Battery with in-use time of 12 hours before needing recharging. Charging time is one hour.
