A WORKSTATION FOR TRACE EVIDENCE ANALYSIS The ffTA is a powerful and flexible multi-functional system that provides the crime laboratory with a range of analytical facilities on a single microscope operated through a single PC. TM By switching from module to module the operator is able to perform a wide range of analytical tasks to extract the maximum amount of forensic evidence in the shortest possible time. Available modules RAMAN SPECTROSCOPY For the study of materials including paint chips, fibres, inks, & drugs Non-destructive analysis of organic compounds including paint & fibres GRIM...

ffTATM Modular Design Built around the Leica DM2700M laboratory microscope with high power LED illumination, the ffTA’s unique modular design enables the user to add functions to meet specific laboratory requirements. Using an optical multiplexer the operator simply switches the image from one module to another.

RAMAN SPECTROSCOPY for the comparison and identification of materials ffTATM FORAM® X3 Triple Raman Spectrometer Module The FORAM® X3 module can be equipped with a choice of one or three laser wavelengths: 785nm (invisible), 638nm and 532nm. High levels of sensitivity can be achieved with the 532nm laser, while the 785nm infrared laser is better able to suppress fluorescence. A balance between power and sensitivity can be achieved through the use of the 638nm laser. Raman spectroscopy is widely used in forensic science for the study of a variety of organic and inorganic materials including...

GRIM® GLASS RI MEASUREMENT for the analysis and grouping of glass samples ffTATM GRIM®3 Glass Refractive Index Measurement Module The ffTATM GRIM®3 module can be used to identify and group fragments of glass through the measurement of their refractive indices using the oil immersion/ temperature variation technique. The system can monitor up to four glass fragment edges per operation, speeding the casework examination process, giving improved statistical accuracy and reducing calibration time. Glass as Evidence As different types of glass have different refractive indices, it is possible to...

POLARISED LIGHT MICROSCOPY for the analysis and identification of fibres ffTATM PLM Light Polarisation Module Possibly the most widely used application for microscopy in forensic science, Polarised Light Microscopy (PLM) is a valuable tool for the detection and analysis of small unknown particles and for the identification of fibres. A contrast-enhancing technique, PLM uses the birefringent properties of materials to improve the quality of the images obtained with the microscope. The addition of a 360-degree circular rotating specimen stage enables the user to make accurate measurements of a...

FLUORESCENCE IMAGING for multi-spectral visual comparison of evidence ffTATM Fluorescence Imaging Real-time Fluorescence Excitation Module A widely used technique for the identification and comparison of trace materials including paint chips, fibres and biological materials. Equipped with four excitation bandwidths: UV, Violet, Blue and Green, this module provides versatile high resolution fluorescence imaging and spectra when used in conjunction with the ffTATM Micro-spectrometer module. Wide Ranging Applications In the forensic laboratory, fluorescence imaging is an ideal technique for...

UV-VIS-IR MICROSPECTROMETER for the analysis of organic compounds ffTATM Microspectrometer Available in a choice of Wavelength Ranges Micro-spectrometry is a powerful analytical tool that is widely used in forensic science for the study and comparison of trace materials including paint chips, fibres and inks. Spectra in the visible region provide the user with objective measurements of colour, and through the examination of ultra-violet and infra-red spectra, users are able to make comparisons between two materials that may be indistinguishable to the naked eye. Spectral analysis Depending...

IMAGE PROCESSING enhancement and comparison of high-resolution images ffTATM Image Processing High-Resolution Camera and Software Module A comprehensive module for processing images from a scientific grade 5 million pixel CCD colour camera. High quality imaging enables the examiner to zoom, orientate and position and item of evidence on screen for critical visual examination. Live and stored images may be compared side-by-side, subjected to digital enhancement (contrast stretch, Fast Fourier Transform, Sharpen etc.), or measured and annotated. Side-by-side comparison of a fibre:  Live image...
