The L Series is Bowman’s most versatile instrument. 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 both large parts, or large sample fixtures holding multiple parts, to be measured. The chamber is fully enclosed and holds 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 for measuring recessed areas. As with other models, the collimator sizes and focal distances are customizable. 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. A high performance SDD detector is optional.
