OPTICAL COMPOHENTS BK-7 Cylindrical Piano Concave Lenses Wide vahety of focal lengths in both prթcision BK7 (pages 75-77) and fused silica (pages 82-84) Idթal for producing line images for scanning and projection Available wilh our complըte range of Anti-Reflection coatings Spթcial aspect ratios available for small and large quantities We offer a slection of very prcise cylindrical lenses, both positive and n驩gative, in glassand fused silica. Thse lenses are well suited for applications which require magnification in one dimension only. Examples indude energy collection for linear detectors or for coupling to a slit input, source gn詩ration for barcode scanners, circularization of diode laser outputs, one-dimensional image compression, and othersimilar applications. j/.n Bmmu Mit ro Opbci r^n'iii ' P'rlfTLh Cylindrical lenses are more drfficult to manufacture than spherical lenses but we take great care to ensure lhat the lens power is confined to a single axis and that the lenses are tightly specified so that you can use them wilh confidence in a complex imaging System. The lenses we offer here represent some of the more gnerai requirements of our customers. But please call if you need a diffrent shape or size. The lenses are uncoated but our standard coatings may be applied by choice of the appropriate coating suffix (see pages 18 and 19).
