Expose Curved Barrier Filter Orange

The Expose Curved Barrier Filter – Orange from Laser Innovations Ltd is an advanced optical accessory designed to significantly enhance ridge detail in forensic photography. This unique curved long‑pass filter is engineered for use with forensic lasers and ALS in the 315–532 nm range, blocking unwanted excitation light while perfectly transmitting evidence-generated fluorescence. Crafted from durable polycarbonate, its curved form compensates for Gaussian roll-off, providing clearer, distortion-minimised imagery

Key Features:

• Optimised Wavelength Range: Long-pass filter designed for 315–532 nm (UV–green) excitation sources.
• Curved Barrier Design: Enhances ridge detail and reduces lens distortion in forensic photography.
• High Optical Density: OD +7 blocks background fluorescence and ambient light, perfect for trace evidence imaging.
• Polycarbonate Construction: Lightweight, rugged, and field‑ready.

Applications:

• Latent fingerprint photography using lasers/ALS
• Fluorescent detection of biological trace evidence
• Imaging of bone fragments, teeth, and other fluorescing tissues
• Enhanced contrast in hair, fibres, and bruising documentation
• Ideal for crime scene and laboratory environments
