Ajax Scientific Polished Spherical Bi Concave Science Education and Optics Review

This bi concave lens is a great addition to any science classroom or personal lab. Its polished spherical design ensures clarity and accuracy in experiments. It`s a versatile piece of Industrial and Scientific equipment that can be used for both educational and professional applications. Its only downside is its fragility, but as long as you handle it with care, it'll provide reliable results for years to come..

Bought for a very specific purpose, to set the focus for a head worn digital eyepiece. The screen felt "too close" to the eye, and this lens mitigates that issue somewhat. However, I'd required an eyeliner makeover that I haven't completed yet, making it difficult to test in real-world conditions. However, the lens was within tolerance for the size described. I haven't measured the focal length, but as the description suggests, "it makes things smaller".
