Aspherical Magnifiers –

 

---

All three magnifiers can be adapted to frontal illuminated or backlit subjects: The magnifier 3× has a half black and half transparent base that can be turned, and both magnifiers 4× and 6× have a sliding skirt that shades frontal light in its lower position for viewing transparancies and allows diffused light to fall through a translucent tube in its upper position for viewing opaque subjects in almost shadow-free illumination. All magnifiers can be adjusted for diopter compensation. Eyeglass wearers can fold down the rubber eyecups; eyeglasses cannot be scratched. The very long eye relief, a large lens and exit pupil diameter provide a very comfortable viewing, allow the eye to move without cropping the large field of view.
