Enhance Your Microscope's Vision

About this item

AmScope A40X 40X Achromatic Microscope Objective Lens is a high-quality, brand-new component designed to enhance your compound microscope's viewing capabilities. With 40X magnification power and an achromatic, spring-loaded design, it offers superior clarity and detail. This lens adheres to the standard DIN/JIS mounting specifications, featuring a 20mm thread diameter, ensuring compatibility with most common size compound and biological microscopes. Upgrade your existing microscope with greater power and clarity at a fraction of the cost of a new unit.

This objective lens is engineered for precision, providing clear and sharp images. The achromatic design corrects for chromatic and spherical aberrations, delivering a flatter field of view compared to simpler lenses. The integrated spring mechanism protects both the lens and the specimen slide from accidental damage during focusing. Its standard DIN 20mm mounting thread ensures a secure fit on microscopes designed for this international standard.

Imported directly from authorized US retailers and brand partners, this AmScope objective lens comes with all customs duties and GST pre-paid. Enjoy the benefit of authentic USA-sourced optical components without the hassle of import taxes. Delivery is handled via ExpressBox, offering tracked shipping to your doorstep across India.

Key Features

  • This brand new 40X (spring) Achromatic microscope objective lens fits common size (DIN/JIS standard) compound microscopes
  • 40X Magnification Power
  • Achromatic Objective Lens (Spring)
  • DIN Standard
  • 20mm Mounting Thread (in diameter)

Why choose this product

Precision Optics for Enhanced Microscopy

AmScope's A40X objective lens delivers professional-grade optical performance. Its achromatic correction minimizes distortions, providing crisp, true-to-life images essential for detailed scientific observation. Unlike basic lenses, this component is designed for a flatter field of view, ensuring consistent clarity across the entire specimen. Imported directly, it offers the quality assurance of USA-sourced components, ensuring your research or educational pursuits are supported by reliable, high-performance optics.

Ideal for Educational & Hobbyist Use

This 40X objective is perfect for students, educators, and microscopy enthusiasts in India seeking to upgrade their compound microscopes. It's particularly suited for observing cellular structures, bacteria, or fine details in biological samples. Those with existing DIN-standard microscopes looking for a cost-effective magnification boost will find this lens invaluable. Users sensitive to image flatness or color fringing will appreciate the achromatic design. If your microscope uses a non-standard thread or barrel size, or if you require oil immersion capabilities, this specific lens may not be the ideal fit.

How to use

  • Remove Old Objective — Carefully unscrew the existing objective lens from your microscope's revolving nosepiece. Store it safely. Ensure the nosepiece threads are clean.
  • Attach New Objective — Gently screw the AmScope A40X objective lens into the appropriate turret position on the nosepiece. Tighten until snug, but do not overtighten.
  • Focus and Observe — Select the 40X objective by rotating the nosepiece. Use the microscope's fine focus knob to bring your specimen into sharp view. Ensure proper illumination for best results.

FAQ, See What Others Asked

How to buy an original AmScope A40X objective lens in India?
All customs duties and Indian import taxes are pre-paid by crowcrowcrow and included in the listed INR price. This AmScope A40X objective lens is sourced directly from authorized US retailers and authorized brand partners, ensuring authenticity. It arrives factory-sealed and is shipped via ExpressBox with tracking for your peace of mind.
Will this AmScope 40X objective lens fit my microscope?
This AmScope 40X objective lens features a standard DIN 20mm mounting thread, compatible with most common size compound and biological microscopes that accept this international standard. Check your microscope's turret specification for the 20mm thread size to ensure a proper fit.
What is the benefit of an achromatic objective lens?
An achromatic objective lens corrects for both chromatic and spherical aberrations, providing sharper images with more accurate color reproduction and a flatter field of view compared to simpler lenses. This results in a clearer, more detailed observation of your specimens.
How does the spring mechanism protect the lens and slide?
The integrated spring mechanism in this objective lens allows it to retract slightly if it accidentally comes into contact with the specimen slide during focusing. This prevents damage to both the delicate lens and the slide, extending the life of your components.
Can I use this objective lens for oil immersion?
No, this AmScope A40X objective lens is not designed for oil immersion. It is a dry objective lens. Oil immersion objectives typically have a higher magnification (like 100X) and require immersion oil between the lens and the slide for optimal image quality.
What is the difference between blank and prepared microscope slides?
Blank slides are clean glass on which you mount your own specimens with coverslips and mounting medium, while prepared slides come with fixed, stained specimens ready to view. Beginners and classrooms often start with prepared sets, while enthusiasts preparing their own samples buy blank slides plus coverslips.
