Focal length: 16.8mm
Apparent field of view: 48 degrees
Eye relief: 15.5mm
Fully multi coated optics

Test results:
We have tested one of the 4.8mm orthoscopic eyepieces and compared with a simple 4mm Plossle of well known brand. Whilst the Plossl showed sharp image only in the center of the image, the ortho was beautifully crisp to the edge of the field of view all around.
This is one of the best purchases on the market and is well worth of the money.
