🔬 Elevate your optics game—see science in a whole new light!
This set includes two 30mm diameter glass lenses: a 5cm focal length double convex lens for focusing light and a 7.5cm focal length double concave lens for dispersing light. Both lenses feature optically polished round edges for safety and durability, making them ideal for physics experiments, photography, and optical instrument applications.
A**S
The biconcave lens has a circular line along the perimeters, ruining the optics
The media could not be loaded. It's not seamless. There is a circular line that runs along the outer line line of it, and it's plainly visible, ruining the optics. I'm not sure if I got a defective one, or if this is how it really is supposed to be, but it was not displayed as such the photos
