L Series open chamber

Bowman L Series XRF

The Bowman L Series XRF offers the largest chamber design and multiple options for ultimate versatility.

Product Overview

The L Series XRF is Bowman’s largest chamber benchtop XRF system. It combines all the advanced features of the P Series with a large, fully enclosed sample chamber and greater X-Y stage travel.

Ideal for samples larger than 12 inches on any dimension, the L Series offers a solution for large parts or fixtures holding multiple parts. An optional RoHS application package provides a turnkey solution for RoHS compliance testing.

Combined with adherence to international testing standards, it offers the ultimate in flexibility for both coating thickness measurement and RoHS testing.

About the Bowman L Series XRF

XRF has become widely recognised as the ideal solution for non-destructive coating thickness measurement. But what if you need to test large parts? The Bowman L Series XRF offers a large chamber solution that allows this industry-standard technique to be applied even to larger plated items.

Boasting a large, fully-enclosed sample chamber, the L series can handle samples up to 550mm x 600mm x 250mm as standard.

The fully programmable X-Y stage expands upon the capacity of the P Series by offering an increased X-Y travel, allowing multi-point measurement over a wider area without the need to re-position samples.

This feature also facilitates the measurement of larger batches of small samples where very high throughput is required. 

L Series open chamber

All the advanced features found on the P Series are retained: micro-focus X-ray tube, variable focal distances, variable collimator sizes, high-throughput SDD detector, laser auto-focus and 30x magnification camera.

In addition, an optional wide view camera allows the user to capture a whole-table image for ease of navigation across large samples. There is also an optional vacuum chuck for light element measurement on silicon wafer applications, and an optional RoHS application package that provides a turnkey solution for RoHS compliance testing.

All the above, combined with Bowman’s guaranteed compliance with standards such as IPC-4552, 4553, 4554, 4556, ASTM B568 and DIN EN ISO 3497 make the L Series the ultimate in flexibility for all your coating application needs.
