Product Introduction

MWIR ODEM825 (40-825 F4.0) is an ideal choice for long-distance thermal imaging applications due to its ultra-long focal length, high sensitivity, and strong environmental adaptability. Whether for security monitoring, industrial inspection, or military reconnaissance, its performance meets the requirements for precise identification and rapid response in complex scenarios. When selecting, it is necessary to comprehensively evaluate the matching degree between the lens and detector based on the specific detection distance, environmental conditions, and system integration requirements.
 

Optical Performance

Focal Length and Zoom ： Focal length range 40-825mm, supports 21x optical zoom, covering observation needs from wide-angle to ultra-long distance. Aperture is fixed at F4.0, optimizing image quality while ensuring light intake.

Detector Compatibility: Compatible with 640×512×15μm cooled detectors, fully leveraging the high sensitivity and resolution advantages of the detector, suitable for low-light or complex environment thermal imaging.

Spectral Range and Field of View: Operating spectral range 3-5μm (mid-wave infrared band), horizontal field of view is 14.4° at the wide-angle end and narrows to 0.67° at the narrow-angle end, enabling precise identification from wide-area scanning to long-distance targets.

Optical Coating: All internal surfaces use high-efficiency anti-reflective coatings; the front surface optionally features diamond-like carbon (DLC) coating to enhance scratch resistance and durability.

 

Application Scenarios

Widely used for day and night all-weather monitoring in border defense, military, public security, safe city, water conservancy, transportation, railway, forest fire prevention, airports, cultural relics, petroleum, petrochemical, mining, factory areas, breeding zones, planting areas, and other industries.
