Hi all, on a few occassions, a sellor on eBay offers images of an objective for sale…but with crucial engravings: 160 , or ‘the infinity sign’ , or ‘0.17’ not shown in the images of the item.

Hi Lou, The infinity objectives can only be used on infinity microscopes. They are a different than the “finite” objectives. As a matter of fact, infinity objectives of different manufacturers are not even interchangeable with each other. It’s not only a question of optical design, also the threading is different. The infinity objectives require additional optics in the body of the microscope. The advantage of the infinity objectives is that it is possible to introduce additional filters into the light beam without changing the focus of the microscope. Oliver.

The magnifying desk lamp is fitted with 60 small switched LED lights surrounding the 5X power magnifying lens (5-1/2 x 7") set in the 9-1/2" x 10-1/2" head. The magnifying lens’ hinged cover can be closed to increase brightness on the surface below. The large base (7 X 11") can be placed anywhere on a desk or table surface and is sufficiently heavy to allow the articulating head to extend up to 22" away when the stability support (shown) is pulled out from the front of the base. If this does not provide enough position flexibility, the Desk Lamp can be lifted off its base and attached to the robust surface clamp (shown) which can be clamped to any surface up to 2-1/2" thick. This will allow the lamp head to rotate to any position up to 34" away from the clamp a total area of 25 sq ft.

“About the numbers on objectives” I thought that this was very useful, but I have seen some lenses with the “infinity” sign. Am I to assume that this type of lens could be used on any tube length ?

It gets frustrating when you contact the sellor, and they do not /can not tell you if the item for sale is a: ‘160’ , or an ‘infinity’ objective. This happened with a black colored objective said to be: “Meles Gerote”/80x…but nothing about wether: ‘160’ , or ‘infinity’ objective.
