Hastings Triplet Geology Loupes
Hastings triplet loupes offer the best performance in terms of achromatic clarity and have a
relatively large viewing area. These magnifiers combine 3 cemented lenses, made from crown and BK7 glass, to correct for
chromatic aberration and barrel distortion.
A 15X lens may be used for geology field studies & is preferred by some rockhounds. The 20X magnifier can be used to view
fungal spores & the 30X for microfractures in jet engine turbine blades. The 20 & 30X magnifiers especially have a
limited depth of field & are NOT recommended for beginners. You should consider buying a lower power
10X geology lens if this is your first loupe.
Note: These loupes are blank on the reverse side & can be printed on with a 1 or 2 color logo. Click on this link
