This is description of this part:
Achromatic microscope objective by Hund Wetzlar.
Manufacturer: Hund Wetzlar
Magnification: 4x
Model: A 4/0.10 160/-
Numerical aperture N.A.: 0.10
Cover glass: not required
Thread: RMS
Tube length: 160 mm
Focal length: 45 mm
Immersion: no (dry objective)
Thread: RMS
This objective can be used both:
- with biological microscopes using transmitted-light illumination
- with inverted microscopes
- with microscopes with reflected-light illumination
- for macro photography by directly connecting it to a camera
This objective fits practically any microscope from any manufacturer, provided that it has an RMS thread and supports objectives for TL=160 mm. Several examples of such microscopes are listed in the "compatibility" section, but this is not a complete list.
Several facts are worth emphasizing:
- many Hund Wetzlar microscope models are identical to models sold by Will Wetzlar due to their joint production. For example, the BX300 and Wilovert models even have the same name. Therefore, Hund Wetzlar microscope objectives can also be used with Will Wetzlar microscopes.
- the companies Eschenbach, Kremp Wetzlar, CBS Beck Kassel and Kosmos Stuttgart also used Will Wetzlar objectives, so Hund Wetzlar microscope objectives can also be used with microscopes from these manufacturers – but it is worth checking the focal length first (37 mm or 45 mm)
- objectives with magnifications below 16x (e.g. 4x / 5x or 10x) fit both classic biological microscopes, microscopes with reflected-light illuminators and inverted microscopes.
What is this part needed for?
- if you have a Hund Wetzlar microscope without a 4x / 5x objective and want to complete it with original parts
- if you are looking for a good-quality 4x objective for a microscope from another manufacturer
- if you already have such an objective, but it is of very poor quality and you want to replace it with a working one
- if you want to keep such a rare objective in reserve
