When choosing an infrared lens for a specific application, several factors need to be considered. First, the required field of view and magnification determine the appropriate focal length of the lens. A wider field of view may require a shorter focal length lens, while a longer focal length provides greater magnification for observing distant objects.
Second, the operating wavelength range of the infrared system should match the transmission characteristics of the lens. Different applications may require lenses optimized for different infrared bands, such as near-infrared, mid-wave infrared, or long-wave infrared.
Third, focus type, such as athermal fixed focus,motorized,manual focus and continuous zoom.
Fourth,detector type cooled or uncooled.
Finally, the resolution, format, pixel pitch and image quality requirements of the application also influence the choice of lens, with higher-resolution applications typically requiring lenses with better MTF and lower distortion.

When installing an infrared lens, it is important to handle it with care to avoid scratching or contaminating the lens surfaces. The lens should be properly aligned and mounted to ensure accurate focusing and optical performance. In some cases, precise mechanical adjustments may be required to achieve the best focus and alignment. Additionally, any necessary accessories or adapters should be used correctly to ensure a proper fit and connection between the lens and the camera or imaging system. It is also crucial to follow the manufacturer's instructions and guidelines for installation to avoid any potential damage to the lens or the equipment.

To clean infrared lenses, it is recommended to use a soft, lint-free cloth or lens cleaning paper. Gently wipe the lens surface in a circular motion to remove dust, fingerprints, or other contaminants. If there are stubborn stains, a small amount of lens cleaning solution specifically designed for optical lenses can be used, but care should be taken not to use excessive liquid that could seep into the lens assembly. Avoid using harsh chemicals or abrasive materials that could damage the lens coatings. Regular maintenance also includes storing the lenses in a clean, dry, and protected environment when not in use to prevent dust accumulation and potential damage. Additionally, periodic inspection of the lens for any signs of damage or degradation in performance is advisable, and if any issues are detected, it may be necessary to have the lens serviced or replaced by a professional.

Present your volume requirements clearly, as larger orders may entitle you to volume discounts. Also, other terms are important, such as payment schedules or delivery times.

The cost of infrared lenses can be affected by several factors. The choice of lens material, with materials like germanium being more expensive than others, significantly impacts the cost. The complexity of the lens design, such as the use of multiple elements or aspheric surfaces for better performance, also adds to the manufacturing cost. The level of precision required in manufacturing, including tight tolerances for surface accuracy and optical alignment, increases production costs. Additionally, any special coatings or treatments applied to the lens for enhanced performance or durability can contribute to the overall cost.
