The field of view when a camera is connected to a borescope and observed on a monitor changes depending on various factors.

 

 

 

This time, we compared the following three points.

　(1) Borescope diameter (φ4mm and φ2.7mm)
(2) Number of camera inches (1/2 inch and 1/3 inch)
(3) f number of connected lens (mm) (35mm and 27mm)

 

 

 

(1) Comparison of borescope diameter between φ4mm and φ2.7mm
(Fixed camera size to 1/3 inch and lens to 35mm)

 

■φ4mm		■φ2.7mm

As mentioned above, increasing the diameter of the borescope will increase the field of view on the monitor.

 

 

 

(2) Compare camera inches between 1/3 inch and 1/2 inch

(Borescope φ4mm, lens fixed at 35mm)

 

■1/3inch		■1/2inch

As mentioned above, reducing the camera sensor size will increase the field of view on the monitor.

 

 

 

 

(3) Comparison of connected lenses between 35mm and 27mm

(Borescope φ4mm, camera fixed at 1/3 inch)

 

■35mm		■27mm

As mentioned above, increasing the focal length of the connecting lens will widen the field of view on the monitor.

 

In addition, our connection lens BA-A1835 allows you to adjust the field of view, so you can further widen the field of view on your monitor.

■■Full-field observation (using 1/2 inch camera)		■During magnified observation (using 1/2 inch camera)

 

By reducing the camera’s sensor size, it can be expanded to almost cover the entire monitor.

(When using 1/3 inch camera and magnifying observation)
