Head (Cameras)

Ball and socket - literally a ball, which rotates in a socket allows camera head to

be maneuvered over a 90° range of motion. Found in all Video Flex and

Vision Viewer Cameras except the 2100 (Explorer), 5500 (ClipCam),

7811 (BookCam), 7821 (ShopCam), 7870 (PhysicsCam), and 910-171-

066 (Ceiling DocCam II). With the exception of the DocCamPro™ AV

(910-171-010) none of the FlexCams by Ken-A-Vision are ball and

socket.

90° Fixed – Camera head is fixed to the end of the flexible neck. All the

exceptions listed above under Ball and Socket, including the FlexCams by

Ken-A-Vision (except the Ceiling DocCam II) are 90° Fixed head

cameras.

Head (Microscopes)

Monocular - single eye tube, set at 45

to the head for viewing by

one observer at a time.

Dual Opposing) Head - Two eyepieces, each of which are at 45

to the

head of the microscope, and set at 180

from each other. This allows two

observers to use the microscope simultaneously, for example a teacher and

the student.

Binocular – Two eyepieces, usually on a slide mechanism. The interpupillary

distance is adjusted side-to-side, by sliding the eyepieces towards and

away from each other.

Seidentopf binocular – Two eyepieces, with the head designed so that by

increasing or decreasing the distance between the two eyepieces

(interpupillary distance) is done by twisting the eyepieces in an

up and down arc motion similar to most binoculars.

Triocular - This microscope has a binocular head for viewing and an additional

eyepiece for a camera mount. Ken-A-Vision trinocular heads have an

80:20 split feature so that when a slide adjustment feature is in position

one, 80% of the light comes to the camera and 20% comes to the binocular

head, allowing a view of what the camera will see. In the opposite

position the slide allows 100% of the light to get to the binocular

eyepieces.
