Product Code : SCL-MI-10785

The achromatic lens 20x/0.40 is a microscope objective used for medium-power observation of prepared slides with compatible compound microscopes. It is designed for schools, colleges, biology laboratories and microscopy training centres that need a 20x achromatic objective for clear specimen viewing.

Product Description

The Achromatic Lens 20x/0.40 is a microscope objective lens for routine educational and laboratory microscopy. The 20x marking indicates objective magnification, while 0.40 refers to the numerical aperture value used for light collection and image resolution.

This objective is useful between low-power scanning and higher-power detailed observation. It helps users examine cells, tissues, prepared slides and transparent specimens with a wider working view than very high-power objectives.

How to Use the Achromatic Lens 20x/0.40

1. Confirm that the objective matches the microscope nosepiece, tube length and optical system.
2. Switch off the microscope illumination before changing the objective.
3. Remove the old objective carefully without touching the optical glass.
4. Fit the Achromatic Lens 20x/0.40 into the correct nosepiece position.
5. Start focusing with a lower-power objective before rotating to the 20x objective.
6. Use fine focus slowly until the specimen image is sharp and evenly illuminated.
7. Clean the lens only when required using approved optical cleaning material.

Do not force the objective, touch the front lens with fingers or install it on an incompatible microscope.

Care & Maintenance

• Keep the objective capped or stored in its protective case when not installed.
• Clean optical surfaces only with lens tissue or approved optical cleaning cloth.
• Avoid dust, moisture, fingerprints and chemical vapours on the lens surface.
• Do not dismantle the objective lens assembly unless serviced by qualified personnel.

Frequently Asked Questions

What is an achromatic lens 20x/0.40 used for?

An achromatic lens 20x/0.40 is used as a medium-power microscope objective for observing prepared slides, cells, tissues and transparent biological specimens.

What does 20x mean on this objective?

20x means the objective provides 20 times magnification before eyepiece magnification is applied. Total magnification depends on both the objective and eyepiece.

What does 0.40 mean on the lens?

0.40 is the numerical aperture value. Numerical aperture relates to light-gathering ability and resolving performance.

Can this lens fit any microscope?

No. Fit depends on the microscope nosepiece thread, tube length, optical system and objective standard. Confirm compatibility before ordering.

Is this objective suitable for school and college labs?

Yes. It is suitable for school and college microscopy when used with a compatible compound microscope and proper laboratory handling.

Are certifications included with this objective?

Certifications should be confirmed before publishing, quotation or tender submission. Do not claim calibration, ISO, CE or optical compliance unless the relevant document is available.
