Very similar to our L3723 and L10094 but smaller and longer focal length.  Edge thickness is 9.7mm, center thickness is 11.9mm. Cemented doublet in great original condition, coated but not color corrected as is.  These work well with other lenses to make exceptional color corrected eyepieces. If you are making your own eyepieces, this lens is for you. Combine this with single elements to make RKE, MPL or other designs. This is the hard to find special doublet that will help make your eyepiece designs spectacular. Cemented doublet with steep curves. Unused.  Limited supply
