Edmund Optics has enhanced its high-quality Tech Spec family of optical components by adding a visible 0° antireflection coating option to its plano-convex, plano-concave, double-convex, double-concave, and achromatic lines of lenses. The coating features an average reflectance of less than 0.4 per cent over the spectral band from 425 to 675nm.
The plano convex line offers effective focal lengths ranging from 4 to 750mm (1 per cent efl tolerance) for diameters ranging from 4 mm to 25 mm. The plano-concave line offers effective focal lengths ranging from -12 to -100mm (1 per cent efl tolerance) for diameters ranging from 12 to 25mm.
The double-convex line offers effective focal lengths ranging from 4.5 to 400mm (1 per cent efl tolerance) for diameters ranging from 4.5 to 25mm. The double-concave line offers effective focal lengths ranging from -6 to -100mm (1 per cent efl tolerance) for diameters ranging from 6 to 25mm.
The line of acromats offers effective focal lengths ranging from 10 to -150mm (2 per cent efl tolerance) for diameters ranging from 6.25 to 30mm.
