FLIR 6° Lens 70 mm FOV 6°x4.5° with Case (T5xx, T8xx, A400/A700)
The 6°, 70 mm IR lens provides outstanding magnification of details at long distances. It is ideal for small or distant targets such as overhead power lines. For science cameras including FLIR A400, A500, A700, T5xx, T8xx cameras.
Highlights
- Super-Narrow Field of View: Approximately 6° horizontal × 45° vertical, helping isolate distant targets in thermal scenes
- 70 mm Focal Length: Offers strong magnification for capturing fine thermal details at long range
- Designed for Remote Targets: Perfect for imaging small or distant objects like power lines, towers, or far-off equipment
- Compatibility: Meant for use with advanced FLIR thermal cameras such as:
- FLIR T5xx series (eg, T530, T540, T560)
FLIR T8xx series (eg, T840, T860, T865)
FLIR A400, A500, A700 science/industrial cameras
- Protective Case Included: Comes with a durable carrying case to protect the lens during transport between jobs
Best Used For:
- Inspecting overhead power lines
- Distant industrial targets
- Detailed remote thermal surveys: The super narrow view and long focal length help your camera see small heat features far away without having to physically move closer
Specifications:
Optical & Imaging Data
Model / Part Number: T300095 (IR lens, f = 70 mm, 6° × 45° field of view)
Field of View (FOV): 6° × 45° — a narrow, super-telephoto view that’s great for tiny or distant targets like power lines or far-off components
Focal Length: 70 mm (28 in) — long focal length for extra reach
Minimum Focus Distance: 50 m (164 ft) — keeps subjects in focus at long range
Spatial Resolution (IFOV): Depends on the thermal camera you pair it with:
• 320×240 sensor: ~034 mrad/pixel
• 464×348 sensor: ~024 mrad/pixel
• 640×480 sensor: ~017 mrad/pixel
Lens Identification: Requires service calibration when installed — it doesn’t auto-calibrate like some other FLIR lenses
F-Number (Aperture): f/135 — bright for thermal lenses, boosting sensitivity
Lens Construction: Multi-element design optimized for IR (exact construction not usually published)
Measurement & Performance
Temperature Measurement Accuracy: About ±3 °C or ±3% of reading under industry-typical conditions — standard for FLIR optical add-ons
Physical Data
Weight: ~042 kg (≈093 lb) — solid but still portable
Size (L × D): ~108 × 75 mm (43 × 30 in) — compact telephoto build
Front Lens Diameter: ~63 mm (25 in) — nice wide front glass to catch IR
What's in the Box:
1 x 6° telephoto thermal lens (70 mm)
1 x Protective case for safe transport/storage
1 x Lens caps/covers to guard optics
