The Noyes OFS-300 Optical Fiber Scope is a handheld visual inspection instrument for fiber optic connector end-faces. It enables technicians to detect contaminants, scratches, and defects that degrade network performance by providing magnified imagery of connector geometry and surface condition. The device resolves defects down to 3/4 micron and accommodates both single-mode and multimode fiber architectures.
Technical Specifications
Magnification: 200x nominal (OFS-300-200B, OFS-300-200C); 400x available in alternative models.
Inspection Resolution: Detects and resolves scratches down to 3/4 micron. Identifies dirt, scratches, and end-face defects across single-mode and multimode connector types.
Optical Protection: Integrated Schott KG3 laser safety filter provides >40 dB IR attenuation to mitigate eye hazard from active fiber signals.
Power: Two AA alkaline batteries deliver up to 60 hours continuous operation. Low-battery LED indicator activates with approximately 8 hours optimum brightness remaining.
Physical: 5 × 2 × 8 inches (13 × 5 × 20 cm); 1.5 lbs (0.67 kg). Ergonomic handheld design with tripod mount for stationary setups.
Operating Environment: 0 to +50°C operating; −20 to +50°C storage.
Optics Control: Momentary power switch and mechanical focus knob for precise image adjustment.
