ZP1 – a plate with an LED module for checking parallelism of film/CCD standard-to-copy without disassembling the camera. The plate contains a 4" square mirror, an LED module, and a UR1 for holding the module. In a non-rigid copy system, such as one that uses a view camera, the plate closely reproduces the weight effect of a Better Light digital insert. The components of either ZV1 or ZV1.1 can be used to make a complete system for checking parallelism of all three optical planes (film/CCD, lens, and copy). ZP3 is for those who do not have ZV1 or ZV1.1.
ZP2 – a plate with a ring module for checking parallelism of film/CCD standard-to-copy without disassembling the camera. The plate contains a 4" square mirror and a ring module and duplicates the weight effect of a Better Light digital insert in a non-rigid copy system. The components of either ZV1 or ZV1.1 can be used to make a complete system for checking parallelism of all three optical planes (film/CCD, lens, and copy). ZP4 is for those who do not have ZV1 or ZV1.1.
ZO1 – a micro-optic for magnifying an LED alignment pattern. It is a small spyglass [not for pirates] and shows additional repeats, making it easier to fine-tune parallelism. It is especially useful when planes are more than ten feet apart and uses the same clamping system as ZTV. Includes LED module.
ZTV – a video tap and 9" monitor for viewing the LED alignment pattern when the module is out of reach. Because the monitor displays the pattern at 36X, ZTV makes the pattern very sensitive. It also can serve as a teaching tool, because many people can see the pattern simultaneously, expanding possible uses of the alignment pattern beyond the sole realm of the technician. (Read about Color3's use of ZTV.) .
The video tap is a miniature digital camera (camera tube) and its lens (objective tube), both of which are positioned on an LED module with a precision 3-point clamping system. Includes LED module.
NOTE: Just as straightness and parallelism of a marching band's rows can be judged from either the sky or the curb, the same can be done with the four half-lines of the LED module's "X" pattern. Judging shape of the pattern from the "curb" is more sensitive than judging from the "sky" [of course, this requires a magic carpet].
Using either your unassisted eye or ZO1 is like looking down from the sky, though pattern magnification of ZO1 is an improvement over using just your eye. ZTV allows you to be either in the sky or at the curb, so you can be as accurate you want. ZTV is like having a manual pattern-recognizing machine and, because of its large magnification, is best used with a custom LED module in order to meet all viewing conditions.
ZO1 and ZTV show more repeats than you can see with your unassisted eye, giving the alignment pattern increased sensitivity. ZTV allows you to see when parallelism (the included angle) changes by as little as 10 seconds of arc.
ZD1-S or ZD1-C – the LED module by itself, available as either standard (-S) or custom (-C). A custom module has dimmable LEDs that improve ease of pattern recognition, especially with ZO1 and ZTV.
Its series #7 top fits series #7 adapter rings, UR1, all ZRs, all ZLs, ZM1, and ZH1. ZD1-S is a standard component of the ZD series and ZP1&3. Two LED modules can be used together for checking concentricity of two planes.
