为什么热像仪镜头价格不同

Choosing a thermal imaging camera lens often raises questions about pricing. 例如, 一个 4毫米镜头 may cost 美元 55, 而一个 35毫米镜头 can cost 美元 210. The price difference is due to several key factors.

---

1. Focal Length and Optical Precision

• Short focal lenses (4毫米): Wide field of view, suitable for near-range observation.
• Long focal lenses (35毫米+): Narrow field of view but can capture distant objects with more detail.

Long focal lenses require higher optical precision and assembly accuracy, which increases production complexity and cost.

2. Material Costs

Thermal lenses use special infrared materials like germanium or chalcogenide glass.

• Long focal lenses often require larger or more complex lens elements, increasing material cost.

---

3. Manufacturing Complexity

• Longer focal lenses have stricter tolerances.
• Production yield is lower, making them more expensive than short focal lenses.

---

4. Application and Market Demand

• Short focal lenses: 大众市场, near-range use, lower price.
• Long focal lenses: Professional, long-distance applications, lower demand, higher price.

---

概括

• 4毫米镜头: 价格实惠, 广角, mass-market use.
• 35毫米镜头: Expensive, 长途, high-precision, professional use.

Understanding these factors helps customers make informed decisions and appreciate the value of long focal lenses.
