Thermal Sight Lens Description:
Focal Length 25mm F1.1 Infrared Germanium Aiming Lens Apply to 640x512-17um Detector
8-12um Long Wave Thermal Sight Lens Suitable for Infrared Sights, Thermal Imager, Drone Monitor, Monitor Camera, Infrared Camera, etc.
What Determines the Quality of infrared Lens:
1. Number of Lenses Used: Combining different types of infrared lenses can improve focus and color accuracy, but it may also reduce the amount of light that passes through.
2. Light Transmittance: High-quality infrared lenses with excellent light transmittance tend to be more expensive, while lower quality infrared lenses may block light from passing through.
3. Coating and Grinding: The quality of the infrared lens is also affected by the technology used for coating and grinding.
4. Mechanical Precision: The internal mechanical structure of infrared lens impacts its accuracy and reliability. A poor quality mechanical structure can cause errors and inconsistencies in adjustments.
