  2. Condenser (optics) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(optics)

    As with objective lenses, a condenser lens with a maximum numerical aperture of greater than 0.95 is designed to be used under oil immersion (or, more rarely, under water immersion), with a layer of immersion oil placed in contact with both the slide/coverslip and the lens of the condenser. An oil immersion condenser may typically have NA of up ...

    en.wikipedia.org/wiki/List_of_standard_zoom_lenses

    There is no precise definition of the term, but lenses marketed as "standard zoom" usually cover a range of at least 30mm to 70mm in terms of 35mm equivalent focal length with an optical zoom ratio of 2.5× (e.g. 28-70mm) to 5× (e.g. 24-120mm) — the most common being 3× (e.g. 24-70mm). [1]

    The pricing of a DOF adapter unit also depends on the material and technologies used. For instance, a relay lens system must be added if the adapter is to be directly mounted to a camera's body (bypassing the standard lens, as if on a Canon XL1 or XL2 and the Sony EX3). Also, a prism system that is used on some adapters that correctly reorients ...

    The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a male 42×0.75 (42 mm diameter, 0.75 mm thread pitch) metric thread on the lens with a flange focal distance of 55 mm and a mating female 42mm thread on a camera adapter or other optical component.

  9. Numerical aperture - Wikipedia

    en.wikipedia.org/wiki/Numerical_aperture

    Numerical aperture of a thin lens. Numerical aperture is not typically used in photography. Instead, the angular aperture of a lens (or an imaging mirror) is expressed by the f-number, written f /N, where N is the f-number given by the ratio of the focal length f to the diameter of the entrance pupil D: =.
