Pin Hole Camera
according to ASTM E1165-20 and
EN 12543 – 2

Measuring the focal spot size of X-Ray
tubes with Digital Detector Array (DDA)

KOWOSPOT X fully digital measurement of focal spot size with results within a minute

The new digital version of the KOWOSPOT Camera allows a fast stand-alone measurement of focal spots.
The digital version consists of the analogue version of the KOWOSPOT with a Digital Detector
Array (DDA) and complete easy to use software package.

– Measurement (ASTM E1165-20 or EN12543-2) within a few seconds
– Complete solution supplied — only a PC with MS WINDOWS® is required
– Storing images (tif) and results (cvs); repeated measurement stored in same cvs file for focal spot evaluation over lifetime of the X-Ray tube
– DDA design for about 6000 focal spot measurements; DDA can be replaced easily
– DDA with 20µm pixel size and special scintillator offer high resolution and efficiency
– Software with auto exposure function and easy to use evaluation (no expert required)
– Modular concept—fits for focal spots from 100µm up to >4mm (FS 0 to FS 17); may be extended to smaller focal spots with restrictions in precision due to pin hole size

DDA Specification:
– 20µm pixel (32µm SRb detector) with structured scintillator
– CMOS sensor protected with fiber glas shielding
– active area 1500 x 1000 pixel
– USB connection – may be extended to 6.5m

Features of the Software:
– automatic detector calibration when plugged in
– automatic evaluation of exposure time (1s..16s)
– image integration for high SNR possible
– automatic calculation of system pixel size
– free style tube descriptor and Serial Number
– scatter reduction with improved background substraction
– results are stored in images and sheet
– already captured images can be re-evaluated
– image size (Zoom) and gray value scaling adjustable
