CERA LT - Frequently Asked Questions

  1. What is CERA LT? CERA LT is a semi-automated forensic optical system designed to aid in the recovery of fingerprint evidence on cartridge casings and other cylindrical objects.
  1. What is CFIS? CFIS, or Consolite Forensics Imaging Software, is unique software which has been designed to operate CERA LT and to aid in the capture and enhancement of detail from cylindrical objects.
  1. What method does CERA LT use to develop prints on cylindrical objects? CERA LT does not physically develop prints. It can reveal and enhance prints using its optical system.
  1. Can the CERA LT help to visualize ridge detail which may be present on the cartridge cases but not visible with the naked eye? Yes, some ridge detail may not be visible with the naked eye yet visible with CERA LT.
  1. Does the ridge detail already have to be visible on the cartridge case prior to using the CERA LT? Ridge detail always has to be present however this might not always be visible with just the naked eye.
  1. What level of fingerprint detail can be captured with CERA LT? CERA LT is capable of capturing fingerprint Minutiae such as ridge bifurcation and endings, as well as finer detail such as sweat pores.
  1. Is CERA LT a photographic tool? CERA LT is a photographic tool to image the circumference of cylindrical items and produce a 360° flattened image. Ridge detail can also be revealed and enhanced through the integrated optical system and software.
  1. Can the CERA LT also be used for non-fired cartridges? Yes.
  1. Is CERA LT only for cylindrical items? Yes.
  1. What size cartridge can CERA LT process? 0.22" Rim fire - 12 Gauge Shotgun 3 ½".
  1. Is CERA LT only for finding corrosive fingerprint residue on metallic objects such as cartridge cases?  No. Many other cylindrical items can be processed.
  1. Can CERA LT be used for other cylindrical objects? Yes. A range of other cylindrical items can be processed i.e. syringes, pens, screwdrivers, batteries.
  1. What size cylindrical object can CERA LT process? Up to 25mm (0.9") diameter and 100mm (3.9") long.
  1. Do the objects have to be metallic for the CERA LT to be used?  No.
  1. Do the non-metallic objects (such as plastic) need prior processing to make any ridge detail visible?  CERA LT can enhance and capture latent prints on some cylindrical items which have not received prior processing. Items which have been subjected to prior processing can also be photographed and enhanced using the system. i.e., powdered, fumed and dyed.
  1. How does CERA LT make visible any ridge detail that may be on non-metallic cylindrical objects? Purely through a combination of lighting and CFIS.
  1. What type of light source does the CERA LT use? The light source is a unique uniform LED cloud sky lighting system in pure white and 460nm blue.
  1. Can CERA LT fluoresce? CERA LT has a 460nm blue light source and 6 position band pass filters to fluoresce cylindrical items which have been subjected to an appropriate fluorescing medium.
  1. What magnification does the lens have? The unique lens specially designed for CERA LT has a fixed optimised focal length with a 3.5x magnification.
  1. Will CERA LT damage the sample? No. Samples are held using a soft jaw system.
  1. Is CERA LT contaminant free? CERA LT has been designed using chemical resistant materials if cleaning is required. The soft jaw holding system is the only part in contact with the sample and can easily be removed for de-contamination.
  1. Can CERA LT image the head of a cartridge? Yes. CERA LT has a soft brush holding system to allow for ballistic examination of cartridge breech face.
  1. What are CFIS photo editing capabilities? CFIS has a large range of photo editing abilities.

This ranges from simple pre-sets such as contrast enhancement and edge enhancement, to more advanced editing tools such as Fast Fourier Transform and digital filters.

  1. What is the average file size of the final image? All images are saved as Tiff files to ensure high resolution imaging and these are approximately 30MB.
  1. What if I need to change the file type or size? All images can easily be changed to multiple formats – jpeg, jpeg2, bmp, tiff.
  1. Can images be output at the correct scale directly to AFIS/IDENT 1 systems? Once the file format and DPI has been initially set to match the system, images can be loaded directly at the click of a single button.
  1. Is additional software needed to convert the images captured in CFIS and directly send them into AFIS? No. This is all instantly done by CFIS.
  1. Can images captured using CERA LT easily be transferred to another computer or AFIS? Yes. Transfer can be via a network or USB drive.
  1. Can CFIS search and match prints? No. CFIS can only capture and enhance a print and output it to identification systems.
  1. Can a scale be added to an image? Yes, CERA LT is a calibrated system which can automatically add a detailed fixed or movable scale to any captured image.
  1. Can the calibration of CERA LT be manually checked? Yes, the system has a calibration tool to allow the user to check for accuracy.
  1. Does CFIS have an audit trail? Yes. CFIS has one of the most detailed audit trails available; ensuring all data from image capture to enhancement is recorded.  Data showing who has accessed the system and which operations have been performed are automatically saved.
  1. Can each image be authenticated? Each original image has its own unique signature to allow for image authentication.
  1. How do you stitch the images? Stitching is simple. Select the cartridge size from an extensive drop down library or by measuring the outside diameter of the cylindrical item. Then at a push of a button CERA LT will capture 8 single images from around the cylindrical object and automatically stitch them together.
  1. How long does the stitching process take? Between 5 – 20 seconds depending on the size of the object.
  1. Can measurements be taken from the captured images? CFIS allows multiple detailed measurements to be taken from images and side by side comparisons made.
  1. What software languages are available?  Multiple languages are available upon request.
  1. Why does CERA LT have a rotary door? The rotary door allows the user the ability to use an external oblique light source to enhance further detail.
  1. Which alternate light sources can be used? CERA LT allows the use of any external light source up to approximately 100mm diameter. Many of the existing light sources on the market can be used.
  1. Are the filters included with CERA LT? Yes. CERA LT has an integrated automated 6 position band pass filter wheel - 495nm, 530nm, 550nm, 570nm, 590nm.
  1. Are there any on-going consumable costs for the system? No.
  1. What is included in the CERA LT system? The system includes CERA LT machine, high resolution monitor and a custom built workstation with CFIS preloaded.
  1. What is the size of CERA LT? Approx. 485 x 350 x 160mm (19" x 13" x 6") 8 Kg (17 ½ Lbs.)
