OPTIMUM TECHNOLOGY

The Ultimate Technology For Supply in Forensic Science

OUR FORENSIC INSTRUCTOR IS AN EXPERT IN HIS FIELD

Milutin Stoilovic -Australian of the Year Nominee

FORENSIC SCIENTIST

Regarded internationally as a leading fingerprint expert and famous for his invention of a device, the Polilight, used in 98 per cent of crime investigations, Milutin Stoilovic now spends much of his time inspiring young people to study science.
A physicist by training, Milutin settled in Canberra in 1980 and was soon employed as a researcher at the Australian National University. There he developed the revolutionary Polilight – a high intensity light source which allows detectives to search crime scenes for previously undetected evidence like fingerprints and blood.
Named as one of Australia’s top 100 inventions, Polilight is now being used in skin treatment and in recycling processes.
After joining the Australian Federal Police, Milutin was part of the team that developed a new fingerprint reagent – Indanedione, that is now used worldwide. His skills took him to Thailand, Malaysia, China, Japan, Korea and the United States to train their forensic investigators.

SOLOMON STAR – SOLOMON News

Forensic officers of the Royal Solomon Islands Police Force (RSIPF) in December 2017 concluded a workshop on fingerprint detection using chemical treatments and optical light enhance techniques using the Polilight.
The workshop, held at the Rove Police Headquarters in Honiara, was facilitated by an Australian Forensic Scientist, Mr Milutin Stoilovic, who invented the ‘POLI LIGHT’ used worldwide at crime scenes and laboratories.

The workshop focused on the following subjects;

  • Fingerprint Laboratory,
  • Light Theory
  • Gathering information using light
  • Forensic light sources
  • Digital Photography
  • Interaction of latent fingermark and a surface

  • Development of latent fingermarks on porous surfaces
  • Development of  latent  fingermarks on non-porous  surfaces
  • Blood & semen detection
  • Sequences for latent fingerprint detection

During the training practical exercises were conducted with

  • Forensic Light Sources and Optical Techniques
  • Development of latent fingermarks on porous surfaces with Ninhydrin and Indanedione-Zinc
  • Development of latent fingermarks on wet non-porous surface-small particle reagent. Development of latent fingermarks on sticky side of tape-Wet Powder.
  • Development of latent fimgermarks on non-porous surfaces.
  • Optical and Chemical Enhancement of Blood.
