Review on ๐ Ultrathin Classroom Magnifying Magnifier with Enhanced Diameter by Melvin Goerge
Does what it's supposed to do
Bought two of these picks for a science project. Came quickly and whole. With a collimated source, the focal length appears to be pretty much right around 50cm, the transmission (500nm visible) is estimated at around 80%, which is unimpressive but normal for acrylic lenses.
Pros
- High light transmission, high focus efficiency, high accuracy.
Cons
- Cord is shorter than other picks
