Cylindrical Lens, +70mm f.l., Mounted
$50.00
This is a plano-cylindrical lens. These lenses have a defined magnification in one direction, and perpendicular to that direction they are effectively ‘unpowered’. Cylindrical lenses find numerous applications in holography, as well as imaging elongated slits in spectrometers and monochromators.
Characteristics of this lens include:
� Focal length – Positive 70mm
� Length – 20mm
� Width – 50mm
� Manufacturer – Unknown
� Part number – 871-20
� Glass type – BK7 ?
� Uncoated
� Condition – no visible defects
Please note – unless we are able to determine that a lens is a higher precision type (either by part number or by nomenclature on the lens itself) then it should be assumed that the lens has a low precision figure. When we have determined that a lens is definitely a low precision grade, then that will be stated in the lens characteristics.
This lens includes a lens mount that is 2 inches wide and 15/16 inches tall. The support shelf sits 1/2 inch above the base. The width of the aperture formed by the support arms is 1 3/8 inches. The bottom portion of the lens has been masked by black tape, easily removed if desired.
