Light sources in instrument and art object analysis are a toolbox for experts

The analysis and expertise of instruments and art objects requires in-depth specialist knowledge, experience and a trained eye. However, some details remain hidden even to the trained expert. In these cases, light analysis comes into play.

Using light sources of different wavelengths, various features of instruments and art objects that escape the naked eye can be made visible. The high-quality forensic flashlight fulfills these tasks.

Flashlights with Spectral Filter and >80% Uniformity

Unlike many conventional UV lamps, the Forensic Flashlights SCHILBACH 365nm (short UV light) & 405nm (long UV light) are equipped with a high-quality spectral filter that largely filters out visible light above the desired wavelength. This significantly reduces the visible light portion and minimally affects the UV output, allowing for precise control. Particularly noteworthy is the integrated lens system, which ensures over 80% light beam uniformity, eliminating bright or dark spots and revealing the finest details. These flashlights with a broad light spectrum are ideal for cleanroom inspections, examining high-value antiques, and instrument analysis, covering all essential wavelengths.

Additional information

• The optimum light source for a particular examination depends on the type of object and the features to be examined.
• As a rule, it makes sense to combine several light sources in order to obtain a comprehensive picture.
• Light analysis should be carried out by experienced professionals who have the necessary knowledge and equipment.
• Only use wavelengths from UV to cyan with long-pass glasses (UV protection)!

Why a special lamp for building forensics?

The principle of the building forensics lamp is based on using short-wave visible light or UV light (e.g. 365 or 445 nm) to cause certain molecules to fluoresce and thus make them visible. This method is particularly effective for chitin, a main component of the cell walls of molds. In this way, mold infestations that are normally invisible to the naked eye can be made visible on building components, walls, ceilings, floors and furniture. The entire mold tissue becomes visible, not just the areas where mold has already formed spores with dyes or pigments.

For example, a plasterboard facing in front of a damp cellar wall shows no abnormalities without a forensic lamp. However, when this is irradiated with short-wave 365 nm UV light, the unpigmented fungal colonies become visible. In building forensics, the lamps not only reveal mold tissue, but also many other substances that fluoresce under short-wave light or UV light. Discoloration and edges caused by water, salts, oils or chemicals are often found in building examinations. These substances can either have been applied deliberately or caused by structural damage. The building forensics lamp therefore offers a wide range of possibilities for examining building components and materials. The long-wave 625nm red light makes it possible to look under slightly opaque paints in order to make substrates or overpainting visible.

Short UV light 365nm & long UV light 405nm

In building forensics, UV light (ultraviolet light) is often used to identify and analyze a variety of materials and substances that remain invisible under normal light conditions.

• Mold infestation
• Moisture and water leaks
• Salt efflorescence
• Chemical residues
• Surface damage and discoloration (surface damage, discoloration and cracks)
• Biological materials (bacteria, algae and certain types of fungi)
• Adhesives and sealants
• Microorganisms and biological contamination

Blue light 445nm

By using 445 nm blue light in building forensics, experts can carry out a detailed inspection and analysis of building structures and materials. This enables the detection of hidden damage, contamination and potential problem areas, allowing targeted remediation measures to be planned.

• Mold infestation
• Biological materials (bacteria, algae and certain types of fungi)
• Moisture and water leaks
• Chemical residues (oils, greases and other organic compounds)
• Salt efflorescence
• Surface damage and discoloration (around surface damage, discoloration and cracks)
• Adhesives and sealants

Cyan light 505nm

In building forensics, cyan light, which lies in the range of visible light between blue and green (around 490-520 nm), is used to visualize certain materials and substances that react less strongly to other wavelengths.

• Moisture and water stains
• Salts and chemical residues
• Biological materials (mold, bacteria and algae)
• Hidden discolorations and stains (organic substances such as oils and greases)
• Inorganic substances

Green light 525nm

• Biological materials (mold, bacteria and algae)
• Chemical residues (oils, greases and other organic compounds)
• Moisture and water leaks
• Salt efflorescence
• Surface damage and discoloration
• Building materials and coatings

Red light 625nm

• Surface changes and damage
• Layer structures and coatings
• Hidden moisture and water damage
• Material differences
• Pigments and dyes
• Building materials and structural integrity

How is a crime scene investigated?

1. First search: After entering the site, the white light output of the multi-band light source is generally used to conduct the first site survey. The main purpose is to investigate whether there are dust footprints, dust fingerprints, hair, fibers, glass fragments, etc., mainly using grazing incidence light.
2. Second-pass and multi-pass search: After the white light search, the trace evidence found should be fixed, extracted and other processing in time. then, make the scene dark as possible, and if conditions permit, it is best to search again in no light conditions. Use multi band fluorescence excitation light source output, wear color filter glasses to conduct multiple on-site surveys, because mayn suspiciouse substances on the site will emit inherent fluorescence, such as: body fluids, fibres, oils, etc.
