Cylindrical lens element 62 series

magnesium fluoride (MgF2)negative achromaticNIR

TECHSPEC® Broadband AR Coated Negative Achromatic Lenses are corrected for color and on-axis aberrations. These lenses, consisting of two optical elements cemented together, are commonly used as Barlow lenses to extend focal lengths. The achromatic lenses are available in various diameter sizes and VIS 0° or VIS-NIR coating options. TECHSPEC® Broadband AR Coated Negative Achromatic Lenses are offered in 6.25 - 25mm diameter options. MgF2 Coated Negative Achromatic Lenses are also available. VIS 0° and VIS-NIR Coatings Common Specifications Bevel: Protective as needed Focal Length Tolerance (%): ±1 Focal Length Specification Wavelength (nm): 587.6 Surface Quality: 40-20 Power (P-V) @ 632.8nm: 1.5λ Irregularity (P-V) @ 632.8nm: λ/4 Need different specs or modifications?
