Frequently Asked Questions
Q: What microscopes are compatible with these achromatic objective lenses?
A: These objective lenses are designed for compound microscopes with a standard 195mm optical tube length and a 20.2mm RMS (Royal Microscopy Society) threaded interface. Most biological and educational compound microscopes use this standard thread size, making these objectives a versatile replacement or upgrade option for a wide range of models.
Q: What is the difference between an achromatic objective and a standard objective lens?
A: An achromatic objective lens is specially corrected to reduce chromatic aberration — the colour fringing that can occur at the edges of an image when light of different wavelengths focuses at slightly different points. This correction results in sharper, more colour-accurate images, particularly important when examining fine biological specimens or detailed structures under high magnification.
Q: Does the 100X objective require immersion oil?
A: Yes, the 100X objective is typically an oil-immersion lens. Immersion oil is applied between the lens and the cover slip to increase the numerical aperture and achieve maximum resolution at this magnification level. Please ensure you have appropriate immersion oil before using the 100X objective.
Q: Can I purchase individual objectives from this set, or is it a complete set?
A: This listing offers the full range of achromatic objectives (4X, 10X, 20X, 40X, 60X, and 100X). Please check the available product variants or contact us to confirm which individual magnifications may be available for separate purchase.
