Toroidal Mirrors TRseries
Highly-Smoothed Surface, High Reflectance, High Quality
Shimadzu toroidal mirrors are manufactured by polishing optical glass with highly-smoothed surface.Standard coating of Aluminum brings high reflectance in ultraviolet region.The newly developed production method secures continuous delivery of stable quality products.Non-Use of Specific Chemical Substances*1
*1. RoHS Directive: Directive on the restriction of the use of certain hazardous substances (mercury, cadmium, lead, hexavalent chromium, PBB and PBDE) in the EU. (EU Directive 2002/95/EC)
Toroidal mirrors are:
Toroidal mirrors are aspherical mirrors where each curvature of orthogonal two axes (horizontal and vertical one) are different. Barrel or Tire shaped with a rotation axis are available.
Difference to spherical mirrors
When a spherical mirror focuses a light from a point source, there appears astigmatism. Toroidal mirrors, however, minimize such astigmatism and make it possible to focus on a small spot. The toroidals are ideal for focusing and/or aberration correction devices for spectroscopes.
