Hastings Triplet 20X

About This Product

The 20X Hastings Triplet shown in the photo is a wide field, distortion free, color corrected three element lens design. The lens is 8mm in diameter and has a 10mmm Field of View and a Focal Length of 12.5mm. The design provides 11mm of working distance and is very suitable for viewing detail features and lines as small as 2 microns on 20 micron center to center distances, or Ronchi Rulings as fine as 60 LP/mm (8.333 micron line and space).

The optics are mounted in a machined black anodized holder with a protective metal cover that swings over the optics and makes this an ideal pocket magnifier for Jewelers, Machinists, Inspectors, Engineers, and Scientists.
