Bench report
- Functional
- Optics clear front and rear. Standard RMS thread, undamaged, turns freely by hand. This objective needed no cleaning. It came to the bench clean and was inspected as found.
- Cosmetic
- Light handling marks on the chrome; green band slightly worn. Engraving fully legible. Comes in the clear screw-top canister shown.
- Tested
- Optics inspected under direct light and against a bright field. Front and rear elements examined at magnification. · No haze, no fungus, no balsam separation, and no chips visible in the glass. · RMS objective thread inspected for burrs, cross-threading, and dings. None found. · Every legible engraving read under raking light and transcribed exactly as marked (see Specifications).
- Not tested
- NOT mounted on a microscope. I do not have a matching stand for it, so resolution, field flatness, parfocality, and working distance at magnification are NOT verified. · No disassembly, recollimation, or internal service performed. · Sold as a used optical component, not as a calibrated or certified instrument.
