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