Walter Auxiliary Lens
Walter Auxiliary Lens (Product Code: SLE/M/85) is a 2x add-on lens used to increase the magnification of a stereo zoom microscope for extreme close-up views of specimens in biology, materials and inspection labs. With the lens in place, the listed magnification range moves from 7.5x–45x to 14x–90x, at a working distance of 30 mm. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for college and research microscope users.

What Is the Walter Auxiliary Lens Used For?
An auxiliary lens is the quickest way to push a stereo microscope beyond its built-in zoom. Doubling the magnification brings out features that are only hinted at in the standard range: the segments of an insect antenna, hairs and glands on a leaf surface, individual fibres in a textile sample, grains in a mineral or the finish of a small soldered joint.
Higher power comes with trade-offs worth planning for. The field of view narrows (listed from 14.2 mm down to 2.2 mm), so centre the feature before zooming in, and the 30 mm working distance leaves less room for forceps or probes, so do any handling at lower power first. More magnification also spreads the light over a larger image, which is why many users pair the lens with a gooseneck illuminator. Keep the glass clean with a microfiber cloth or lens tissue — at 90x every smudge shows. It is a sensible upgrade for biology lab instruments in college and research settings.
What to Specify When Ordering
- The make and model of the stereo microscope the lens will be fitted to, so we can confirm compatibility.

Frequently Asked Questions
What magnification does the Walter Auxiliary Lens add?
The Walter Auxiliary Lens is a 2x lens. With it fitted, the listed magnification range changes from 7.5x–45x to 14x–90x, giving extreme close-up views of small structures that are hard to resolve at the microscope’s normal settings.
What field of view does the Walter Auxiliary Lens give?
The field of view with the Walter Auxiliary Lens is listed as 14.2 to 2.2 mm across the zoom range. The field shrinks as magnification rises, so centre the feature of interest before zooming in.
What is the working distance with the auxiliary lens fitted?
The Walter Auxiliary Lens gives a working distance of 30 mm between the lens and the specimen. That is enough for viewing, but it leaves limited room for dissecting tools, so plan manipulations at lower magnification.
Will the Walter Auxiliary Lens fit my microscope?
Fit depends on your stereo microscope’s make and mounting. Before ordering the Walter Auxiliary Lens, send us the model of the microscope it will be used on through the contact page so that we can confirm compatibility.
Is ScienceLab the maker of the Walter Auxiliary Lens?
No. The Walter Auxiliary Lens carries the Walter brand name. Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, supplies it to schools, colleges, research labs and dealers along with related microscope accessories.
How should the Walter Auxiliary Lens be cleaned and stored?
Clean the Walter Auxiliary Lens with a soft microfiber cloth or lens tissue after removing loose dust, so grit does not scratch the glass. When it is not fitted, store it covered in a dry, dust-free place away from chemical fumes.
