What are prism loupes?

What is the 10x objective lens called?

Low Power Lens (10x)

This objective can be very useful for viewing prepared specimens on slides. It will achieve somewhere around 100x to 200x magnification for a 10x or 20x eyepiece respectively. This sort of magnification is great for viewing small specimens like: Fly legs.

What is the total magnification of the ocular is 10x and the objective is 40X?

What is 20x magnification? In general, a 20x objective maps 0.5 microns (of the specimen on the slide) to a single pixel on the camera. The final magnification is obtained by dividing the display pixel size (in microns) by the pixel mapping. For a 70″ HD TV (1920×1080), the pixel size is about 0.8mm (800 microns).

Why are my loupes blurry? Please note though, that it is normal to see a blurry image as you move the optical barrels closer or farther apart or up and down. This is because you are still trying to adjust the loupes to match your PD and the ideal declination angle.

What magnification do snipers use? While their standard 10x scope is the ideal magnification for target at medium to long range, it’s best suited for 250 to 1000 yards.
