78mm Standard UV Fixed Focal Length Lens, #57-543
UV Fixed Focal Length Lenses are ideal for use in a variety of applications, including the surface inspection of circuits or fiber optics, quality control of semiconductor materials, or for locating oil contamination or leakage. Additional applications include forensic, pharmaceutical, or biomedical imaging, fluorescence, security, or counterfeit detection. UV Fixed Focal Length Lenses are manufactured from fused silica elements to provide excellent transmission from the ultraviolet to the near-infrared.
Note: These lenses are not corrected for chromatic aberration, and require refocusing when using an illumination source with a spectral bandwidth greater than 10nm. A monochromatic light source and narrow bandpass filter are recommended to improve the overall performance of the lens. The 78mm lens (#57-543) has a removable C-mount adapter, enabling it to be used with M42 x 0.75 (T2) mounts.
