Product Summary: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Features
Like the N-BK7 plano-convex cylindrical lens, this Ø1" positive round cylindrical lens can be used to focus light but only in one dimension. However, it has the added advantage that it is epoxied into a round cell, allowing it to be mounted in our SM1 Lens Tubes or any Ø1" Lens Mounts. The cell is black anodized and engraved with the part number, focal length, and coating information (if applicable). The wall thickness is designed to allow full contact with the cylindrical lens when using an SM1RR retaining ring to hold the lens. One possible application is to use this lens to focus fluorescence from a gas cell into a thin line imaged onto a photomultiplier tube. Alternatively, pairs of cylindrical lenses can be used to collimate and circularize the output of a laser diode. To minimize the introduction of spherical aberrations, collimated light should be incident on the curved surface when focusing it to a line, and a line source should be incident on the plano surface when collimating.
