Bandpass

Viewing Goggles & Camera Filters

A unique range of narrowband viewing goggles and camera filters that isolate a band of wavelength from the total spectrum and have been specifically tuned for the detection of a single evidence type.

A with all Foster + Freeman viewing goggles and camera filters, bandpass products are manufactured from Schott glass with an additional coating to supress auto-fluorescent emissions from the Schott glass itself. This ensures maximum optical performance, particularly when using high power light sources.

Bandpass goggles and camera filters are currently available to match the following evidence types:

• Blood - centered on a wavelength of 415nm
• Semen - centered on a wavelength of 530nm
• Body fluids - centered on  a wavelength of 550nm
