Cylindrical Lens, +40mm f.l., Mounted

Description

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 40mm
� Length – 20mm
� Width – 15mm
� Manufacturer – Unknown
� Part number – Unknown
� 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 has been mounted in a circular cell, 52mm in diameter. This cell is in turn mounted in an outer ring of 65mm diameter. The clear central aperture of the inner lens support is 18mm.
