MSE PRO™ Positive Achromatic Doublets with 1/4 Wave MgF2 Coating@550nm, Ø2"
MSE supplies offers Ø2" Positive Achromatic Doublets with 1/4 Wave MgF2 Coating@550nm. An achromatic-doublet consists of a positive low-index (crown glass) cemented with a negative high-index (flint glass) lens. These lenses are computer-optimized for infinite conjugate ratio. They also exhibit excellent partial performance, with minimal spherical aberration, coma and chromatic aberration. When used for imaging, the convex lens should face the object or the image that is furthest away.
MSE Supplies can offer a variety of optical elements, with different focal length and coating options. Please contact us for customization or bulk orders.
