镜头选择与安装

This guide shows you how to select the right lens for your application and safely replace lenses on the OV10i camera. The lens choice determines your Field of View (FOV) and working distance.

本指南向您展示如何为您的应用选择合适的镜头，并安全地更换 OV10i 摄像头的镜头。镜头的选择决定了您的 Field of View (FOV) 与工作距离。

When to Use This Guide: When you need to change working distance, adjust field of view, or replace a damaged lens.

【使用本指南的情境】：当您需要改变工作距离、调整视野，或更换损坏的镜头时。

Prerequisites​

  • OV10i 摄像头系统
  • 十字螺丝刀
  • 替换镜头（6mm、8mm、12mm、16mm，或 25mm）
  • 对于 25mm 镜头：需要额外的定位垫片套件组件

Step 1: Calculate Required Lens Size​

1.1 Determine Your Requirements​

  • Working Distance：相机与零件之间的距离
  • Field of View：需要检查的区域宽度
  • Part Size：您要检测的工件尺寸

1.2 Use FOV Chart for Lens Selection​

Field of View (FOV) Widths at Different Distances:

Camera Specifications:

  • Aspect Ratio：4:3
  • FOV Height：Width × 0.75
  • Standard Lens：12mm（随摄像头附带）

1.3 Online Calculator​

Use the OV10i Calculator for precise FOV calculations based on your specific mounting distance and lens requirements.

使用 OV10i Calculator，根据您的具体安装距离和镜头需求，进行精确的 FOV 计算。

Step 2: Standard Lens Replacement (6mm to 16mm)​

2.1 Remove Faceplate​

  1. Power down the camera

  2. Remove four corner screws on the faceplate using Phillips-head screwdriver

  3. Carefully lift off the faceplate to expose the LED board and lens

  4. 断电 摄像头

  5. 使用十字螺丝刀 移除前面板上的四个角螺丝

  6. 小心取下前面板，露出 LED 板和镜头

2.2 Replace Lens​

  1. Unscrew existing lens by turning counterclockwise (hand-tight only)

  2. Install new lens by turning clockwise

  3. Hand-tighten only - do NOT use tools to avoid damage

  4. 逆时针旋拧现有镜头（仅手拧）

  5. 顺时针旋拧新镜头

  6. 仅手拧 - 禁止使用工具以避免损坏

注意

Over-tightening can damage the lens or camera threads.

注意

过度拧紧可能损坏镜头或相机螺纹。

2.3 Reassemble​

  1. Replace faceplate on camera

  2. Secure with four screws removed earlier

  3. Power on and test focus

  4. 将前面板重新安装到摄像头上

  5. 用先前拆卸的四颗螺丝固定

  6. 通电并测试对焦

Step 3: 25mm Lens Installation (Special Procedure)​

3.1 Additional Components Required​

  • M12 25mm lens
  • 15mm faceplate spacer
  • Spacer rings
  • 4x M3x22 socket head cap screws

3.2 Determine Spacer Configuration​

  1. Remove faceplate as in Step 2.1
  2. Set up camera at working distance
  3. Slowly screw in lens until image is sharp
  4. Measure lens extension beyond mount
  5. Select spacer rings to match measured distance

3.1 需要的额外组件

  • M12 25mm 镜头
  • 15mm 前面板定位垫片
  • 定位环
  • 4x M3x22 内六角螺钉

3.2 确定定位垫片配置

  1. 如步骤 2.1 移除前面板
  2. 将相机设置在工作距离
  3. 慢慢旋入镜头，直到图像清晰
  4. 测量镜头在安装座外的伸出长度
  5. 选择定位环以匹配测量得到的距离

3.3 Install 25mm Lens​

  1. Slide spacer rings onto lens to correct size

  2. Install lens with spacers into camera mount

  3. Hand-tighten clockwise

  4. Attach 15mm faceplate spacer with M3x22 screws

  5. Place original faceplate onto spacer

  6. 将定位环滑入镜头以调整到正确尺寸

  7. 将带定位环的镜头安装到摄像头安装座

  8. 顺时针方向仅用手拧紧

  9. 使用 M3x22 螺丝将 15mm 前面板定位垫片固定

  10. 将原始前面板放置到定位垫片上

Step 4: Focus and Test​

4.1 Initial Focus Check​

  1. Power on camera

  2. Navigate to Imaging Setup in camera interface

  3. Use Focus View to achieve optimal sharpness

  4. Adjust focus using camera controls

  5. 给相机通电

  6. 在相机界面导航至 Imaging Setup

  7. 使用 Focus View 以获得最佳清晰度

  8. 使用相机控件调整对焦

4.2 Verify Field of View​

  1. Check FOV covers required inspection area

  2. Ensure part positioning fills appropriate portion of image

  3. Confirm image quality meets inspection requirements

  4. 检查 FOV 是否覆盖所需的检测区域

  5. 确保工件定位在图像的适当部分

  6. 确认图像质量符合检验要求
