Objectives for the Swift Microscope

I would like to purchase 3-4 60X objectives that will fit my Swift Microscopes (M7003D). Previously, I purchased Swift's DIN achromatic 60X objectives (N.A. is 0.85 and other numbers etched on tube are 160 /0.17) which worked fine with these scopes, but they no longer carry these objectives at Swift. Please send me specs. and purchase prices for my high school scopes. Diana

Hi

If your objectives are parfocal 45mm, you can use the LOMO Objective, Q-Plan Achromat.
