of
eyecup sensitivity, sufficient time (1-4 min) was given between two stimulations.
The loose
eyecup must have been an afterthought, and the APO-Televid 82 name sucks, but that's where the complaints stop.
Doesn't the absence of an
eyecup give the face a green glow that makes the head an inviting target?
The remaining
eyecup was then carefully everted atop a conical mound of wax and fastened to the wax with minuten pins.
Application of the zinc chelator histidine (100 [micro]M) in the presence of the GABA-blocker picrotoxin (200 [micro]M) doubled the amplitude of the skate electroretinogram (ERG) b-wave recorded in the skate
eyecup preparation (4).
I've already started collecting the peripherals such as ammo, magazines and a nifty reproduction of the ZF4 4X scope complete with rubber
eyecup, sunshade and wooden carry case.
Each of these 1 1/4-inch oculars is designed with 20 millimeters of eye relief and a twist-up
eyecup, allowing eyeglass wearers to comfortably enjoy the entire 50[degrees] field.
This procedure involved enucleation of the
eyecup and fixation in primary fixative (2.5% glutaraldehyde, 1% paraformaldehyde in 0.06 M phosphate buffer, pH 7.3); post-incubation of extracted retinas in secondary fixative (1% osmium tetroxide) for I h at 4[degrees]C; dehydration of the tissue through a series of ethanol solutions of increasing concentration; and embedding in Epon plastic.
Skate horizontal cells are isolated as follows: the eyes are removed, and the retina separated from
eyecup pieces.
Featuring a magnification range from 20x to 60x, the SX-1 Ventana offers a wide field of view, fully multicoated lenses and twist-up
eyecup. Tripod features adjustable legs with a 1/4-20 mounting screw head and twist-lock panning control arm.
Like the Bushnell Quest, the LRB 7x50SPD has a one-piece body and left-eye interpupiliary adjustment, but it does not have center focus, instead requiring individual
eyecup diopter adjustment.
Each has an adjustable
eyecup and long eye relief for users with eyeglasses.
