Cylindrical Lens, Negative 250mm f.l., Mounted

$75.00

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 – Negative 250mm
� Length – 60mm
� Width – 51mm
� Manufacturer – Melles Griot
� Part number – 01-LCN-011
� Glass type – BK7
� Low precision figure
� 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 plain aluminum double-ring mount. The outer ring is 3.875 inches in diameter. The lens is mounted on an inner sleeve which can be oriented within the outer sleeve and clamped. The sleeves are both 1/2 inch in thickness. The clear aperture of the inner sleeve is 65mm.
