Hi, The text is about a microscope and I don't understand the meaning of sheer in this context.
Three different sheer types are available on our DIC prisms, allowing for standard, high-contrast or high-resolution observations.
Could anyone please explain what is meant here?
Thanks.
Best regards,
Antje

angular splitting of coaxial orthogonal wavefronts
This glossary might help you, Antje!
Example sentence:
Shear - Angular splitting of coaxial orthogonal wavefronts resulting in a spatial separation defined by a specific angle (the shear angle).
Shear Angle - The specific angle defined by angular separation of paraxial orthogonal wavefronts as they become displaced and spatially separated in a Wollaston or Nomarski prism.

diaphanous
"Sheer, has several meanings, but this is one definition I found:
diaphanous: so thin as to transmit light.
This seems possible for something in a microscope slide.

: Hi Jack. I don't have the correct answer but am almost 100% sure this one is not. I don't see how "diaphanous" can be applicable here.//Exactly the problem as I see it: lenses/prisms are translucent regardless of how thin or thick they are.

I'm not suggesting that diaphanous should actually be used in this context, I'm just trying to convey the idea of something thin enough to be translucent.

: Wow! Thanks - this just linked up with a Danish expression that has puzzled me for years: the word dias for photo transparencies that needed a projector before we all went digital. From diascope according to the dictionary, but it's all Greek ... :-)

Thank you. The more technical term for them was diapositives, but transparencies became more commonly used in English. In Russian they were always diapozitivy.

image parameter
We use our model to demonstrate how parameters such as sheer and bias affect imaging properties of both confocal and conventional scanning type DIC microscopes.
http://www.opticsinfobase.org/DirectPDFAccess/8B531388-BDB9-...
The module uses this information to crop and re-scale the image to fit the expected horizontal size calculated from the theta resolution in the image parameters. If the Sheer parameter has been set, the module will sheer the image so that the two points have the same height. In general, this has no effect in reducing possible matching errors throughout the image, however, it has a desirable the visual effect.
