Advanced Dark-Tube Pin-Hole Imaging Device for Precision Photography
1, Purpose:
This instrument is suitable for primary school science students to explore small hole imaging experiments in groups. structure
The instrument consists of a detachable cassette, frosted glass, small square orifice plate, small triangular orifice plate, and large, medium, and small circular orifice plates. 3, Operation usage
(1) Imaging of the small triangular orifice plate: Push open the front end of the cassette, then place the small triangular orifice plate into the front end of the cassette and secure it. At this point, the inverted image can be seen through the frosted glass at the rear of the dark box.
Attention: Operate in a well lit area.
(2) Imaging of small square orifice plate: Push open the front end of the cassette, then place the small square orifice plate into the front end of the cassette and secure it. At this point, the inverted image can be seen through the frosted glass at the rear of the dark box.
(3) Imaging of small circular orifice plate:
Open the front end of the cassette, then insert the small circular orifice plate into the front end of the cassette and secure it. At this point, the inverted image can be seen through the frosted glass at the rear of the dark box.
(4) Imaging of a circular orifice plate:
Open the front end of the cassette, then insert the circular orifice plate into the front end of the cassette and secure it. At this point, the inverted image can be seen through the frosted glass at the rear of the dark box.
(5) Imaging of large circular orifice plate:
Open the front end of the cassette, then insert the large circular orifice plate into the front end of the cassette and secure it. At this point, the image cannot be seen through the frosted glass at the rear of the dark box.
Conclusion: Small hole imaging is related to the size of the hole, and cannot be imaged when the hole is too large, regardless of the shape of the hole
