Achromatic Cylindrical Lens


Achromatic Cylindrical Lens
In stock
A cylindrical achromat is single component made by bonding two cylindrical surface lenses having different refractive indexes. The resulting achromat creates fine lines close to the theoretical limit. The cylindrical achromat is recommended if blurred lines and color bleeding is a concern when using cylindrical plano-convex lens (CLB-P).

◦It is designed so that difference of focusing point is reduced as much as possible in the visible light range.
◦Optical adjustment is easy to do as direction of the condenser line will be parallel to the side of the diameter (B).
◦It can be used as a substitute for a slit spectrograph.
