L SERIES XRF

L Series XRF

Bowman brand XRF for large parts 12″ to 24″

The L Series is the most versatile instrument that Bowman offers. It combines all of the features of the P Series with a larger sample chamber and greater X-Y stage travel. For samples larger than ~12 inches (300 mm) in any direction, the L Series is a must-have. The large sample stage and travel allows for both large parts, or large sample fixtures holding multiple parts, to be measured. The chamber is fully enclosed and boasts a capacity to hold samples up to 22″ (550mm) x 24″ (600mm) x 13″ (330mm) (LxWxH). The X-Y stage travel distance is 10″x10″ (254mm x 254mm).

The standard configuration includes a 4-position multiple collimator assembly, and a variable focus camera allowing for measurement in recessed areas. As with other models, the collimator sizes and focal distances are customizable for different customer applications. The programmable X-Y stage is included, but can be removed to allow for the maximum sample height capacity (10″ (254mm) z-height with stage, 13″ (300mm) without). The solid-state PIN detector is included along with our long-life micro-focus x-ray tube. The high performance SDD detector is an optional upgrade.
