Description

The Crime-lite Imager, an evidence recording system, is designed to meet the varying demands of forensic photography providing optimum illumination for all types of evidence and backgrounds:

Latent &Treated Fingerprints includes preset examinations for all common fingerprint treatments

Trace Evidence including body fluids, fibres, paint, glass fragments and gun shot residues

Counterfeit & Altered Documents examine all handwritten and printed documents

Combining advanced imaging and multi-wavelength illumination with simple to use software the Crime-lite Imager is the only digital imaging system for forensic applications with two distinct modes of operation providing rapid, high qualty results for users with varying degrees of photographic expertise.


 

Professional results in minutes without training:

Using the Automatic Mode of operation, effective imaging and enhancement can be achieved in 3 simple steps.

1   Place evidence under the Crime-lite Imager

2   Select a preset evidence type from the drop-down menu

Dual-Mode Software

The Crime-lite Imager provides two modes of operation both offering rapid, high quality imaging results:

Automatic Mode

Expert photographic practice is made simple using the Automatic Mode of operation where enhancement options are presented as a simple dropdown list.

Having selected the type of evidence and evidence treatment the Crime-lite Imager automatically performs a number of preset standard enhancements displaying each enhanced image in a thumbnail gallery.

  • Fingerprints, includes commonly used chemical treatments
  • Documents, handwritten and printed

Advanced Mode

In Advanced Mode the operator may select and apply specific image enhancement processes with full manual control of lighting, filters and post imaging enhancement.

This mode allows an expert operator to fine tune the enhancement process.

Advanced Mode features include:

  • High resolution imaging system providing both 5 Megapixel 14bit monochrome and 15 Megapixel colour imaging.
  • High sensitivity, scientific grade camera and optimised colour corrected lens giving high contrast, high resolution images in the visible and infrared wavelengths from 400-1000nm.
  • Maintenance free integral LED ringlight providing intense focussed multi-wavelength illumination
  • Variable wavelength narrow band light source for advanced hyperspectral imaging of fingerprints on highly coloured backgrounds
Colour extraction is used to enhance fingerprints on 'busy' backgrounds

Enhancements are applied to a fingerprint on a shopping bag treated with BY40
