Review on 🔍 Ajax Scientific Double Convex Bi-Convex Spherical Optics for Science Education by Jason Vigil

For a project I ordered two lenses with a diameter of 50 mm and a focal length of 50 mm and two lenses with a diameter of 50 mm and a focal length of 150 mm. I prepared for the reception and processed the holders. When they arrived each was individually bubble wrapped with a size tag. I could see the envelope inside each bubble wrap. As I removed the bubble wrap and moved on to the envelopes, I discovered that what was labeled 50mm x 50mm was actually 38mm x 50mm. Wrong diameter! So my editing time was wasted and the project was put on hold while I figured out what to do. From the pluses it can be seen that the lenses are fine. Unsatisfied.
