4 Detection of Latent Fingerprints The detection of latent fingerprints is enhanced by the ability to use a variety of light sources spanning the optical spectrum. LatentMaster is the only workstation which has a proprietary, high sensitivity solid state video camera (not a CCD camera) with all quartz optics that spans the spectrum from infrared nm to deep ultra-violet nm. The camera sees what the human eye cannot, and the image is displayed, in real time, on a high resolution computer monitor. In many cases latent finger-prints can be detected and lifted without chemical treatment, using ultra-violet absorption, ultra-violet reflection, or ultra-violet fluorescence. The latent fingerprint shown was lifted with LatentMaster using UV illumination. This latent fingerprint was deposited on glass. No chemical treatment was used.

5 NON CONTACT LIFTING OF LATENT FINGERPRINTS LatentMaster lifts latent fingerprints with the press of a button! Unlike conventional photography, you see displayed on the computer monitor exactly what you will lift so that optimum results are obtained every time. Not only does LatentMaster save time, but in many cases, a better lift is obtained than can be achieved with photography. Latent fingerprints which can be seen by the eye, or seen after dusting or chemical treatment can be immediately and non-destructively lifted. The lifted prints are stored on a disk file in the computer for later viewing, image enhancement or hardcopy printout. Displayed Camera Live-Image Just press F9 to snap a Fingerprint!

6 The System LatentMaster is a complete advanced electronic latent fingerprint workstation. It has state of the art computers, electronics, and software written specifically for processing latent fingerprints. It uses a specially designed, high sensitivity, solid state video camera with quartz optics to allow consistent sensitivity and sharpness in the IR, UV, and visible spectrums. LatentMaster will allow you to: Detect more latent fingerprints than any other Latent Fingerprint Workstation. Produce photo quality images across the spectrum, even in the UV spectrum. Significantly reduce the time required to lift, photograph, and print latent fingerprints to scale. Use the most powerful latent fingerprint enhancement software on the market. Automatically document each step of the process for complete traceability, including capture. Examine evidence in realtime under a broad spectrum from IR to UV using a variety of light sources.

7 A Revolution for Fingerprint Analysis LatentMaster is not just software, but a complete advanced electronic latent fingerprint workstation which uses state of the art computers and electronics, software written specifically for processing latent fingerprints, and a unique high sensitivity, solid state video camera with all quartz optics. This camera is NOT a UV sensitized CCD camera, and is NOT an image intensified camera. It is a proprietary solid state camera which has the same sensitivity, low noise, and sharpness in the UV spectrum as in the visible spectrum. LatentMaster is the only system currently on the market which spans the spectrum from infrared (1100 nm) to deep ultra-violet (200 nm) without a loss in sensitivity or clarity. LatentMaster will detect more and better latent prints than ANY other electronic video imaging system, will significantly reduce the time required to process latent prints, and will result in more identifiable latent prints as well. BEFORE AFTER LatentMaster is by far and away the fastest, most powerful image enhancement system available at any price. LatentMaster is currently being used by the more advanced forensic laboratories in Europe, and has made a positive identification possible in a number of important cases which otherwise would not have been solved.

8 The Software EASY TO USE SOFTWARE LatentMaster software was developed specifically for fingerprint enhancement by a team of knowledgeable software engineers. This software was designed to be simple to learn and easy to use yet it incorporates the most powerful tools available for the image enhancement of latent fingerprints, such as fully interactive Fourier processing with a comprehensive set of Fourier Filters. File handling is simple and automatic. You cannot accidentally overwrite the original latent fingerprint image. A complete log of every processing step is automatically generated. Any process performed can be undone at the click of a mouse, so there is no fear of making an unrecoverable error and ruining the previous work. Of course, this powerful software runs in Windows 98/2000/XP. HARDCOPY Hardcopy output can be produced by any Windows compatible printer at any scale, from 1:1 to the full size of the paper. The is no need to adjust the distance from the camera to the evidence to set the scale. Scaling is internal to the LatentMaster software - if a ruler or object of known size is in the image, the exact scale can quickly be set.

9 FAST DIGITAL IMAGE ENHANCEMENT Digital image enhancement of latent fingerprints has been accepted in court on numerous occasions, and has been instrumental in the identification, arrest, and conviction of many criminals who would have otherwise never been identified. LatentMaster has a comprehensive set of image enhancement processes developed specifically for the enhancement of latent fingerprints, such as Brightness/Contrast, Kernel Filtering, Unsharp Filtering, Histogram Equalization, Fourier Processing, and many, many more. Most of these processes, including Fourier Processing, are real time and interactive - you see the results as you perform the process. LatentMaster image processing can, in many cases, produce a clearly identifiable latent fingerprint from a formerly unusable latent fingerprint. The latent fingerprint above is from an actual case, deposited on electrical tape used in constructing a letter bomb. The latent was lifted with UV illumination and enhanced using LatentMaster Fingerprint Software.

10 The Components Latentmaster Quarz Lens This lens was custom developed for Elephant Engineering to our demanding specifications. It produces an extremely sharp and clear image at 254 nm. A similar 105 mm Quartz lens is also available, however our 78mm lens produces a sharper, higher contrast image with the LatentMaster camera. We also sell a 25 mm quartz lens for other UV applications. The 25 mm lens has the same clarity in the UV spectrum as our 78 mm lens, but has a much larger field of view - 25 cm at 52 cm. Specifications: - C-Mount & T-mount - 3 element 78 mm F3.8 all Quartz lens - 49 mm thread for filter holders - Spectral response (80%) 200nm to over 2,000 nm - Designed to image a 2.5 cm by 2.5 cm area at 30 cm - At 250 nm: Focal length: mm Back focal: mm Fringe back: (C-mount) Image Circle: 18.0 mm - Angle of View at infinity: 6.64 degrees diagonal - Optical distortion (at infinity): -.27% diagonal - Magnification: Front lens aperture: 23 mm - Rear lens aperture: 21 mm - All surfaces single MgF2 coated

11 LatentMaster Gold Broadband IR-VIS-UV Camera Shown here is the latest version of our famous cooled UV camera - the LatentMaster GOLD camera. Like the previous version of our famous camera, it has hermetically sealed head backfilled with Argon for a long life with no maintenance. Unlike a CCD camera, there is no image blooming when part of the image is saturated. The cooler ON-OFF switch has been removed, since there is no reason to ever turn the cooler OFF. The LatentMaster GOLD camera has lower noise and an even sharper image. There are a whole bunch of improvements inside the camera controller box (a 7.5" x 9.25" x 1" black box), like wider bandwidth, higher gain, and closed loop cooling control. Specifications: - Quantum efficiency: 35% - Pixel size: 15x15 um - Active area: mm - better than 51 db S/N - Geometric Distortion: 0% - Frequency Response: 1100 nm to 200nm - Gold colored - anodized gold --> all pieces in the cases are electronically connected to shield the camera head from electronic noise
