Pentax XW40-R Eyepiece

The Pentax XW40-R Eyepiece features high-performance XW-series optics with high-refraction and extra-low dispersion lanthanum glass elements. Combined, they deliver a well-balanced image with reduced optical aberrations. Its main purpose is to minimise the disturbing blackout effect via effective compensation for spherical aberration of the pupil.
