Specifications

How Does It Compare with JLab’s Achromatic Objectives?

Choose this listing for routine replacement objectives, including the 15x power and the Olympus-type 100x, which the achromatic set does not list. Choose the Achromatic Objectives when you need a stated optical correction, an anti-fungus coating, an oil-immersion 100x, or the 2x, 4x, 20x and 60x powers.

What Is a Microscope Objective Lens Used For?

The objective is the lens closest to the specimen. It forms the first magnified image, which the eyepiece then enlarges again. Low powers such as 5x and 10x are used to locate the specimen and scan a slide; 40x and 45x reveal cell detail in onion-peel, cheek-cell, stomata and tissue preparations in school biology practicals; and 100x objectives are normally used with a drop of immersion oil for bacteria and blood smears in college microbiology and pathology teaching labs. Schools and colleges order spare objectives when lenses get scratched, clouded or lost, or to complete a nosepiece with every power their practical syllabus needs.

Fit an objective by screwing it into the nosepiece finger-tight. Lower the stage before swinging a high-power objective into place and focus upwards, so the front lens never touches the slide. Clean immersion oil off the 100x with lens tissue as soon as you finish, and keep spare objectives capped and dry, because optics stored in humid rooms can grow fungus.

What to Specify When Ordering

• Powers and quantities — list how many 5x, 10x, 15x, 40x, 45x and 100x objectives you need, and say if you want the Olympus-type 100x.
• Microscope make and model — the listing does not give the thread size, so JLab needs it to confirm the fit.
• Immersion — state whether your 100x must be an oil-immersion objective.
• Quantity and other spares — the minimum order is 10 units in total; eyepieces, a condenser or lens tissue can go on the same enquiry.

Frequently Asked Questions

Which magnifications are available?
5x, 10x, 15x, 40x, 45x and 100x, plus a 100x made to the Olympus-type pattern. Give the number of each power you need in your enquiry.

What does “Olympus type” mean for the 100x?
It names the design pattern this 100x objective follows. The objective itself is made by JLab at its Ambala works and is not an Olympus-brand product. The listing gives no further detail, so ask JLab to confirm its thread and the microscopes it suits.

Will these objectives fit my microscope?
They are standard screw-thread objectives for student and medical microscopes, but the listing does not state the thread size. Send your microscope’s make and model and JLab will confirm the fit with the quotation.

Is the 100x an oil-immersion objective?
The listing does not say. A 100x objective is normally used with immersion oil, so confirm the type with JLab if your practicals need one.

How is total magnification worked out?
Multiply the objective power by the eyepiece power: a 40x objective used with a 10x eyepiece gives 400x.

How does it differ from JLab’s Achromatic Objectives?
That listing states achromatic correction, an anti-fungus coating and an oil-immersion 100x, and covers 2x, 4x, 20x and 60x powers. This listing adds a 15x and the Olympus-type 100x and does not state the optical correction.

What information is needed for an export quotation?
The quantity of each power, your microscope models, the destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling needs, and the tender reference if there is one.

Who manufactures these objectives?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes them at its works in Ambala, Haryana, India, and quotes for them directly as the manufacturer.

OEM Manufacturer

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of school and college laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These objectives, the Olympus-type 100x included, are made at JLab’s own works rather than bought in from a trader, so schools, colleges, dealers and importers looking for a microscope objective lens from India deal factory-direct; each objective is visually inspected before dispatch, and repeat orders and spares are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Yemen in the Middle East, Paraguay in South America, Lesotho in Southern Africa, Ghana in West Africa and Norway in Northern Europe. Tender details are on the JLab lab tenders page.
