The frame rate of a high-speed camera plays a significant role in determining its cost. Higher frame rates require more advanced and expensive components such as specialized sensors, processors, and memory modules to capture and process the increased amount of data in real-time. Additionally, higher frame rates often necessitate more robust cooling systems to prevent overheating during prolonged use, further adding to the overall cost of the camera. Therefore, a high-speed camera with a higher frame rate will typically be priced higher than one with a lower frame rate due to the increased complexity and sophistication of its design and components.
