為什麼熱像儀鏡頭價格不同

Choosing a thermal imaging camera lens often raises questions about pricing. 例如, 一個 4MM鏡頭 may cost 美元 55, 而一個 35MM鏡頭 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: 大眾市場, near-range use, lower price.
• Long focal lenses: 專業的, long-distance applications, lower demand, higher price.

---

概括

• 4MM鏡頭: 負擔得起, 廣角, mass-market use.
• 35MM鏡頭: Expensive, 遠距離, high-precision, professional use.

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