LM digital SLR universal wide-field adapter: now with larger image field and focus settings

The new and improved version of our popular C-mount microscope adapter

Our tried and tested C-mount microscope adapter has been updated and improved. The new LM wide-field adapter has a phototube with C-mount connection (1x) and an image field enlarged by 25% (in comparison to our standard LM adapter)!

Like all our products, the LM digital SLR universal wide-field adapter is characterised by its precision workmanship and top-quality design. It is focusable and has a sophisticated plan achromatic lens design. The wide-field adapter uses the whole image field of the microscope – even the edges of the image are shown on the photo. Therefore we recommend using the LM wide-field adapter only with high-quality microscopes with fully corrected lenses (e.g. infinity corrected plan achromats, plan flourites, plan apochromats, etc.). With lower-quality microscope lenses (without the “plan” denotation) it is not possible to get the centre and the edges of the image in focus simultaneously since these lenses mostly show a pronounced focus field curvature. Looking through the eyepiece, however, the image appears in focus because the human eye is able to focus on objects at different distances. This process is called accommodation.

To increase flexibility, two C-mount 5 mm extenders are also included with the adapter.
