–Candela 7300 Inspection Tool (Candela 7300) is a device for performing the optical and electrical tests and can be incorporated to Ambient Fixture Tester; 

–Candela 7300 is able to perform the next tests:      CBCP (cd), CCT (K), u’v’, Load Power (W), Load Voltage (V), Load current (A), illuminance (lx) and to perform the morphological analysis of acquired images; –All parameters tested are set for Pass/Fail criteria with saving in spreadsheet report, and with saving of acquired images as a primary and as a morphologically processed sourced edges and baffled center beam of tested fixture. 

Candela 7300 can be incorporated to Ambient Fixture Tester for mass production

Clamps made from Delrin for smooth and reliable fastening

Candela 7300 is used with auto bar scanner for accurate and fast inventory control and database creation. USB3 hub is used to establish 15Gbit speed for image acquisition and all peripheral
