ASTRAL PHOTODIODE DETECTORS

The Astral Series photodiode detectors are perfect for microwatt to 30mW cw power measurements. The AP30 and AP30UV photodiode detectors are powered by the Vector Synergy Indicators Models H410 and H410D to provide optimum performance with ease of use including automatic wavelength correction. These detectors come with an aperture extension for blocking out unwanted light sources. The slip-fit aperture 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. The detectors also come with a standard sized 1.27 cm diameter x 8.89 cm long mounting post for mounting to optical tables. Optional bases (Model 301-019) are available for holding the detector/post assembly upright on a tabletop.

With an aperture diameter of 7.9 mm (an area of 0.5 cm2), power density (intensity) determinations are made easy.
